Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, circuits, etc. well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0039] The target object slotting method of the embodiment of the present disclosure can be executed by an electronic device. The electronic device can be a terminal or a server. Exemplarily, the electronic device can be a terminal device with computing capabilities. Exemplarily, the electronic device can be a server in the cloud; the server can be a single server, or can be at least one server in a server cluster, or can be a server in a distributed system (or can be called a computing node).

[0040] The three-dimensional design scene can be: a design scene involving a three-dimensional model with three-dimensional space features created by an application. For example, in the field of interior decoration and renovation, the design scene used to construct a three-dimensional model of a building and its apartment structure, as well as a three-dimensional model of office furniture and / or a three-dimensional model of living furniture in an interior space, is only illustrative here. The three-dimensional design scene can also be: in the field of industrial design, a design scene used for the appearance and structure design of a product, such as a car, home appliance, etc. Or in the field of film and television and game production, it is used to create design scenes such as characters, maps, props, etc. It can be understood that as long as it involves a three-dimensional model design scene, it is within the scope of this application, and no further enumeration is given here.

[0041] The target object and target 3D model are explained with examples. For example, in the field of interior decoration, the target object can be the 3D model of any wall in the apartment structure, and the target 3D model can be the 3D model of a wall lamp, storage cabinet, downlight, etc. embedded in any wall. For another example, the target object can be the 3D model of a kitchen cabinet, and the target 3D model can be the 3D model of a sink or stove embedded in the cabinet, etc.

[0042] The target object and the target three-dimensional model can each be composed of multiple faces. Taking any face in the target object or the target three-dimensional model as an example, the any face can be composed of multiple mesh faces, wherein each mesh face in the multiple mesh faces can be a polygonal face, the edges of the polygon can be referred to as the edges of the mesh face, and the vertices of the polygon can be referred to as the vertices of the mesh face. The shape and size of the polygonal face can be set according to actual conditions and are not limited in this application.

[0043] The method of determining, on a target surface of the target object, the digging areas corresponding to the one or more target three-dimensional models when one or more target three-dimensional models are embedded in the target object in the three-dimensional design scene, includes: judging whether there are one or more target three-dimensional models embedded in the target object in the three-dimensional design scene, and determining, on the target surface of the target object, the digging areas corresponding to the one or more target three-dimensional models when one or more target three-dimensional models are embedded in the target object in the three-dimensional design scene.

[0044] In one example, when one or more target 3D models are not embedded in a target object in a 3D design scene, rendering processing is performed on the target object and other 3D models in the 3D design scene. The method for rendering the target object and other 3D models in the 3D design scene is not limited in this application; for example, the rendering processing may include texture rendering, material rendering, lighting rendering, and the like.

[0045] Taking the g-th target 3D model among the one or more target 3D models as an example, determining a manner of embedding the one or more target 3D models into the target object may include one of the following:

[0046] In a case where a portion of the g-th target three-dimensional model is located inside the target object and one or more intersecting surfaces of the multiple surfaces of the target object intersect with the g-th target three-dimensional model, determining that the g-th target three-dimensional model is embedded in the target object;

[0047] If the g-th target three-dimensional model is located inside the target object and none of the multiple faces of the target object intersects with the g-th target three-dimensional model, the g-th target three-dimensional model is determined to be embedded in the target object, where g is a positive integer greater than or equal to 1.

[0048] The target surface may be one or more of the multiple surfaces of the target object. Hereinafter, the target surface of the target object may also be referred to as the one or more target surfaces of the target object. In other words, the target surface of the target object and the one or more target surfaces of the target object have the same meaning.

[0049] The method of determining the one or more target surfaces of the target object may include: determining the one or more target surfaces among the multiple surfaces of the target object based on positions where the one or more target three-dimensional models are embedded in the target object.

[0050] Taking the gth target three-dimensional model among the one or more target three-dimensional models as an example, determining the one or more target surfaces among the multiple surfaces of the target object based on the positions where the one or more target three-dimensional models are embedded in the target object may include one of the following:

[0051] If a portion of the g-th target three-dimensional model is located inside the target object, and one or more intersecting surfaces intersecting with the g-th target three-dimensional model exist among the multiple surfaces of the target object, use the one or more intersecting surfaces among the multiple surfaces of the target object that intersect with the g-th target three-dimensional model as one or more first target surfaces corresponding to the g-th three-dimensional model among the one or more target surfaces;

[0052] If the g-th target three-dimensional model is located within the target object and none of the target object's multiple faces intersects with the g-th target three-dimensional model, one or more designated faces corresponding to the g-th target three-dimensional model are used as the one or more first target faces corresponding to the g-th three-dimensional model among the one or more target faces. The one or more designated faces can be set based on actual circumstances and are not limited in this application.

[0053] Through the solution provided by this embodiment, when one or more target three-dimensional models are embedded in a target object in a three-dimensional design scene, the digging areas corresponding to the one or more target three-dimensional models are determined on the target surface of the target object; then, based on the digging areas corresponding to the one or more target three-dimensional models, the geometric structure of the target surface of the target object after digging is determined; and then, based on the geometric structure of the target surface of the target object after digging, the geometric structure of the target object after slotting is determined. In this way, the geometric structure of the target surface of the target object after digging can be obtained through the digging areas corresponding to the one or more target three-dimensional models, and then the geometric structure of the target object after slotting can be obtained through the geometric structure of the target surface after digging, without the need for manual slotting of the target object, thereby improving the efficiency of slotting the target object.

[0054] In one embodiment, determining the digging area corresponding to the one or more target three-dimensional models on the target surface of the target object includes: when there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, selecting the current target three-dimensional model from the one or more remaining target three-dimensional models; and determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target part of the current target three-dimensional model located inside the target object.

[0055] In one example, taking the current target three-dimensional model as the g-th target three-dimensional model as an example, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target part of the current target three-dimensional model located inside the target object can include: using the target part of the g-th target three-dimensional model located inside the target object, and the area of ​​the vertical projection on one or more first target surfaces corresponding to the g-th target three-dimensional model, as the one or more digging areas corresponding to the g-th target three-dimensional model.

[0056] Taking the kth first target surface among the one or more first target surfaces corresponding to the gth target three-dimensional model as an example, using the target portion of the gth target three-dimensional model located inside the target object, and the area of ​​the vertical projection on the one or more first target surfaces corresponding to the gth target three-dimensional model, as the one or more hole-digging areas corresponding to the gth target three-dimensional model, may include: using the target portion of the gth target three-dimensional model located inside the target object, and the area of ​​the vertical projection on the kth first target surface corresponding to the gth target three-dimensional model, as the kth hole-digging area corresponding to the gth target three-dimensional model, where k is a positive integer.

[0057] In one example, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target part of the current target three-dimensional model located inside the target object includes: determining one or more sections corresponding to the target part based on the target part of the current target three-dimensional model located inside the target object, wherein the one or more sections include at least one of the following: the target surface, one or more other sections parallel to the target surface and located inside the target object, different other sections among the one or more other sections have different distances from the target surface, and the distance between each other section and the target surface is less than or equal to the maximum vertical distance between the target part and the target surface; determining one or more outer contours of the target part based on the one or more sections corresponding to the target part; determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the union of the one or more outer contours of the target part in the vertical direction of the target surface.

[0058] Taking the current target three-dimensional model as the g-th target three-dimensional model as an example, determining multiple sections corresponding to the target part based on the target part of the current target three-dimensional model located inside the target object may include: based on one or more first target surfaces corresponding to the g-th target three-dimensional model and the target part of the g-th target three-dimensional model located inside the target object, determining one or more groups of sections corresponding to the target part, wherein each group of sections in the one or more groups of sections includes one or more sections.

[0059] In one example, taking the kth first target surface among the one or more first target surfaces corresponding to the gth target three-dimensional model as an example, determining one or more groups of cross sections corresponding to the target portion based on the one or more first target surfaces corresponding to the gth target three-dimensional model and the target portion of the gth target three-dimensional model located within the target object may include: when the kth first target surface intersects the gth target three-dimensional model, determining one or more other cross sections based on the target portion of the gth target three-dimensional model located within the target object and the kth first target surface; and using the kth first target surface and the one or more other cross sections as the kth group of cross sections among the one or more groups of cross sections corresponding to the target portion. The one or more other cross sections in the kth group of cross sections are parallel to the kth first target surface and located within the target object, different other cross sections in the one or more other cross sections in the kth group of cross sections have different distances from the kth first target surface, and the distance between each other cross section in the kth group of cross sections and the kth first target surface is less than or equal to the maximum perpendicular distance between the target portion and the kth first target surface.

[0060] The determining of one or more other sections based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface may include: determining the last other section, and / or one or more intermediate other sections based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface, and using the last other section, and / or one or more intermediate other sections as one or more other sections.

[0061] Determining the last other section based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface can include: taking the surface located at the maximum vertical distance between the target part and the k-th first target surface and parallel to the k-th first target surface as the last other section in the k-th group of sections.

[0062] The method of determining one or more other intermediate sections based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface may include: taking one or more surfaces whose distance from the k-th first target surface is less than the maximum vertical distance between the target part and the k-th first target surface, which are parallel to the k-th first target surface and located inside the target object, as one or more other intermediate sections.

[0063] In one example, still taking the kth first target surface among the one or more first target surfaces corresponding to the gth target three-dimensional model as an example, the one or more groups of cross-sections corresponding to the target part are determined based on the one or more first target surfaces corresponding to the gth target three-dimensional model and the target part of the gth target three-dimensional model located inside the target object, including: when the kth first target surface does not intersect with the gth target three-dimensional model, one or more other cross-sections are determined based on the target part of the gth target three-dimensional model located inside the target object and the kth first target surface; and the one or more other cross-sections are used as the kth group of cross-sections among the one or more groups of cross-sections corresponding to the target part. Among them, one or more other sections in the kth group of sections are parallel to the kth first target surface and are located inside the target object, different other sections in the one or more other sections in the kth group of sections have different distances from the kth first target surface, the distance between each other section in the kth group of sections and the kth first target surface is less than or equal to the maximum vertical distance between the target part and the kth first target surface, and the distance between each other section in the kth group of sections and the kth first target surface is greater than or equal to the minimum vertical distance between the target part and the kth first target surface.

[0064] The determining of one or more other sections based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface may include: determining at least one of the following based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface: the first other section, the last other section, and one or more intermediate other sections; and using at least one of the first other section, the last other section, and one or more intermediate other sections as the one or more other sections.

[0065] The method of determining the first other section based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface may include: taking the surface located at the minimum vertical distance between the target part and the k-th first target surface and parallel to the k-th first target surface as the first other section.

[0066] The method of determining the last other section based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface may include: taking the surface located at the maximum vertical distance between the target part and the k-th first target surface and parallel to the k-th first target surface as the last other section.

[0067] A method for determining one or more intermediate sections based on the target part of the g-th target three-dimensional model located inside the target object and the k-th first target surface includes: taking one or more surfaces located between the minimum vertical distance between the target part and the k-th first target surface and the maximum vertical distance between the target part and the k-th first target surface and parallel to the k-th first target surface as the one or more intermediate other sections.

[0068] In a preferred example, distances between adjacent sections in one or more sections in the kth group of sections corresponding to the target portion are the same.

[0069] It can be understood that the method for determining each group of cross sections in the one or more groups of cross sections corresponding to the target portion is the same as the method for determining the kth group of cross sections in the above example, and will not be repeated here.

[0070] In one example, determining one or more outer contours of the target part based on multiple sections corresponding to the target part may include: determining multiple intersection points of the current target three-dimensional model and the i-th section based on each mesh edge of each mesh surface among multiple mesh surfaces of the current target three-dimensional model, where i is a positive integer and the i-th section is one of the one or more sections corresponding to the target part; and determining the i-th outer contour among the one or more outer contours of the target part based on multiple intersection points of the current target three-dimensional model and the i-th section.

[0071] Taking the current target three-dimensional model as the g-th target three-dimensional model and the i-th section as an example, determining the multiple intersection points between the current target three-dimensional model and the i-th section based on each mesh edge of each mesh surface in the multiple mesh surfaces of the current target three-dimensional model may include:

[0072] determining whether there is an unprocessed mesh edge in each mesh edge of each mesh surface of the g-th target three-dimensional model; and if there are one or more unprocessed mesh edges in each mesh edge, selecting a current mesh edge from the one or more unprocessed mesh edges;

[0073] Determine whether there is an intersection between the current mesh edge and the i-th section; if the current mesh edge and the i-th section do have an intersection, use the intersection between the current mesh edge and the i-th section as one of the multiple intersections between the g-th target three-dimensional model and the i-th section, return to execute the above-mentioned determination of whether there is an unprocessed mesh edge in each mesh edge of each mesh surface of the multiple mesh surfaces of the g-th target three-dimensional model, and continue to execute subsequent processing; if the current mesh edge and the i-th section do not have an intersection, return to execute the above-mentioned determination of whether there is an unprocessed mesh edge in each mesh edge of each mesh surface of the multiple mesh surfaces of the g-th target three-dimensional model, and continue to execute subsequent processing;

[0074] If there are no one or more unprocessed mesh edges in each of the mesh edges, the process of determining the multiple intersection points of the g-th target three-dimensional model and the i-th section is terminated. The multiple mesh faces of the g-th target three-dimensional model may be one or more mesh faces of each of the multiple faces of the g-th target three-dimensional model.

[0075] Still taking the current target three-dimensional model as the g-th target three-dimensional model and the i-th section as the i-th section in the k-th group of sections in the one or more groups of sections as an example, determining the i-th outer contour in one or more outer contours of the target part based on multiple intersection points of the current target three-dimensional model and the i-th section may include: connecting the multiple intersection points of the g-th target three-dimensional model and the i-th section in a specified order to obtain the i-th outer contour in the k-th group of outer contours in the one or more groups of outer contours of the target part of the g-th target three-dimensional model located inside the target object.

[0076] The method for determining the specified order may include: determining the order of the multiple vertices of the multiple mesh surfaces based on the topological structure of the multiple mesh surfaces of the g-th target three-dimensional model; determining the order of the multiple mesh edges of the multiple mesh surfaces based on the order of the multiple vertices of the multiple mesh surfaces; and using the order of one or more mesh edges of the multiple mesh surfaces that intersect the i-th section as the specified order. The multiple vertices of the multiple mesh surfaces may be obtained by treating the vertices at the same position in each vertex of each mesh surface in the multiple mesh surfaces as a vertex to obtain the multiple vertices of the multiple mesh surfaces. The multiple mesh edges of the multiple mesh surfaces may be obtained by treating the mesh edges at the same position in each mesh edge of each mesh surface in the multiple mesh surfaces as a mesh edge to obtain the multiple mesh edges of the multiple mesh surfaces.

[0077] Among them, the topological structure of the multiple grid surfaces can be set according to actual conditions and is not limited in this application.

[0078] Combine Figure 2 In a possible example, a method of determining the topological structure of the plurality of mesh surfaces is exemplarily described, which may include:

[0079] S201. Determine whether the current sort is the first sort. If the current sort is the first sort, execute S202; if the current sort is not the first sort, execute S203.

[0080] S202: Use any grid surface among the plurality of grid surfaces as the grid surface corresponding to the current sorting, and return to execute S201. The arbitrary grid surface can be set according to actual conditions, and this application does not limit it.

[0081] S203. Determine whether there are one or more unsorted mesh surfaces among the multiple mesh surfaces. If there are one or more unsorted mesh surfaces among the multiple mesh surfaces, execute S204; if there are not one or more unsorted mesh surfaces among the multiple mesh surfaces, execute step S205.

[0082] S204 . Determine one or more mesh surfaces adjacent to the last sorted mesh surface among the one or more unsorted mesh surfaces, use any of the one or more mesh surfaces adjacent to the last sorted mesh surface as the mesh surface corresponding to the current sort, and return to step 201 .

[0083] S205 : Determine a topological structure of the plurality of mesh surfaces based on the order of each mesh surface in the plurality of mesh surfaces.

[0084] Combine Figure 3 In a possible example, determining the order of the vertices of the plurality of mesh surfaces based on the topological structures of the plurality of mesh surfaces may include:

[0085] S301. Determine whether the current sort is the first sort; if the current sort is the first sort, execute step S302; if the current sort is not the first sort, execute step S303.

[0086] S302: Use the first mesh surface in the topological structure as the current mesh surface, use any vertex in the current mesh surface as the vertex corresponding to the current sorting, and return to execute S301.

[0087] S303. Determine whether there are one or more unsorted vertices among the one or more vertices of the current mesh surface; if one or more unsorted vertices exist among the one or more vertices of the current mesh surface, execute S304; if one or more unsorted vertices do not exist, execute S305.

[0088] S304: Take the unsorted vertices in the current mesh surface that are adjacent to the last sorted vertices as the vertices corresponding to the current sort, and return to execute S301.

[0089] S305: Determine whether the current mesh surface is the last mesh surface in the topological structure. If the current mesh surface is not the last mesh surface in the topological structure, execute S306; if the current mesh surface is the last mesh surface in the topological structure, terminate the sorting of the multiple vertices of the multiple mesh surfaces.

[0090] S306 : Determine the next mesh surface based on the order of each mesh surface in the multiple mesh surfaces in the topological structure; use the next mesh surface as the current mesh surface, and return to execute S301 .

[0091] Determining the order of the multiple mesh edges of the multiple mesh surfaces based on the order of the multiple vertices of the multiple mesh surfaces may include: using the order number (or vertex subscript label) of the vertices corresponding to each of the multiple mesh edges of the multiple mesh surfaces as the order number (or mesh edge subscript label) of the multiple mesh edges of the multiple mesh surfaces. For example, if the order numbers of the two vertices corresponding to any one mesh edge are 2 and 3, respectively, then the order number of the order of the any one mesh edge is 23 or 32. It should be understood that this is only an exemplary description, and the specific method for determining the order number of any one mesh edge can be set according to actual conditions and is not limited by this application.

[0092] It can be understood that the method of determining each outer contour in each group of outer contours in one or more groups of outer contours corresponding to the target part is the same as the method of determining the i-th outer contour in the k-th group of outer contours in one or more groups of outer contours of the target part, and will not be repeated here.

[0093] In this way, based on the multiple mesh edges of the multiple mesh surfaces, multiple intersection points between the current target 3D model and the i-th section are determined; then, based on the multiple intersection points between the current target 3D model and the i-th section, the i-th outer contour among the one or more outer contours of the target part is determined. In this way, each outer contour can be obtained more accurately.

[0094] Still taking the current target three-dimensional model as the g-th target three-dimensional model and the i-th section as the i-th section in the k-th group of sections in the one or more groups of sections as an example, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the union of multiple outer contours of the target part in the vertical direction of the target surface may include: determining the k-th digging area corresponding to the g-th target three-dimensional model on the k-th first target surface corresponding to the current target three-dimensional model based on the union of the k-th group of sections of the target part of the g-th target three-dimensional model located inside the target object in the vertical direction of the k-th first target surface.

[0095] In this way, the digging area corresponding to the current target 3D model can be obtained more accurately through the union of one or more outer contours of the target part of the current target 3D model located inside the target object in the vertical direction of the target surface.

[0096] Combine Figure 4 and Figure 5 , this embodiment is exemplarily described, including:

[0097] S401. Determine whether there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models; if there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, execute S402; if there are not one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, execute S404.

[0098] S402: Select a current target three-dimensional model from the one or more remaining target three-dimensional models.

[0099] S403 : Based on the target portion of the current target three-dimensional model located inside the target object, determine a digging area corresponding to the current target three-dimensional model on the target surface of the target object, and return to execute S401 .

[0100] S404: Determine the geometric structure of the one or more target surfaces of the target object after the holes are dug based on the dug areas corresponding to the one or more target three-dimensional models on the one or more target surfaces of the target object.

[0101] Taking any target surface among the one or more target surfaces of the target object as an example, determining the geometric structure of the target surface of the target object after the hole is dug based on the digging area corresponding to the one or more target three-dimensional models on the target surface of the target object may include: adjusting one or more mesh surfaces of the arbitrary target surface based on the digging area corresponding to one or more first target three-dimensional models in the one or more target three-dimensional models on the arbitrary target surface of the target object to obtain the adjusted one or more mesh surfaces of the arbitrary target surface; and using the adjusted one or more mesh surfaces of the arbitrary target surface as the geometric structure of the arbitrary target surface after the hole is dug. Wherein, the position of the one or more mesh surfaces of the arbitrary target surface after the adjustment is different from the position of the digging area corresponding to the one or more first target three-dimensional models in the one or more target three-dimensional models on the arbitrary target surface.

[0102] Take the example of only one first target 3D model, combined with Figure 5 , based on the digging area corresponding to one or more first target three-dimensional models in the one or more target three-dimensional models on any target surface of the target object, adjusting one or more mesh surfaces of the arbitrary target surface is exemplified. Figure 5 As shown in FIG: Based on the digging area 5031 (i.e., the area corresponding to the rectangle formed by the dotted line) corresponding to a first target three-dimensional model in the one or more target three-dimensional models on the arbitrary target surface 501, one or more grid surfaces 5011 (i.e., Figure 5), obtaining one or more mesh surfaces 5021 (i.e., Figure 5 The face of each triangle in any target face 502 in FIG. 1 ). It can be seen that Figure 5 The position of the mesh surface 5021 in the arbitrary target surface 502 after adjustment is consistent with the digging area 5032 (i.e. Figure 5 The position of the area corresponding to the solid rectangle in the arbitrary target surface 502 is different. It will be understood that this is merely an example. When there are multiple first target 3D models (i.e., an arbitrary target surface includes multiple digging areas corresponding to the first target 3D models), the method for adjusting one or more mesh surfaces of the arbitrary target surface is similar to that when there is only one first target 3D model, and will not be further described here.

[0103] S405 : Determine a geometric structure of the target object after grooving based on the geometric structures of one or more target surfaces of the target object after the holes are dug.

[0104] Specifically, determining the geometric structure of the target surface after digging based on the digging areas corresponding to the one or more target three-dimensional models on one or more target surfaces of the target object may include: using the geometric structure of one or more target surfaces of the target object after digging and one or more other surfaces of the target object as the geometric structure of the target object after grooving.

[0105] S406: Render the target object based on the grooved geometric structure of the target object.

[0106] The method of rendering the target object based on the grooved geometric structure of the target object is not limited in this application. For example, the rendering process may include texture rendering, material rendering, lighting rendering, etc.

[0107] In this way, the existence of a current target 3D model is determined by determining whether one or more remaining target 3D models have undetermined digging areas in the one or more target 3D models. If a current target 3D model exists, the digging area corresponding to the current target 3D model is determined on the target surface of the target object based on the target portion of the current target 3D model located within the target object. This ensures that a corresponding digging area can be determined for each of the one or more target 3D models, thereby improving the accuracy of determining the digging areas corresponding to the one or more target 3D models.

[0108] In one example, determining the digging areas corresponding to the one or more target three-dimensional models on the target surface of the target object includes: when there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, selecting a current target three-dimensional model from the one or more remaining target three-dimensional models; determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target part of the current target three-dimensional model located inside the target object; when there are one or more other target three-dimensional models with the same relevant parameters as the current target three-dimensional model in the one or more remaining target three-dimensional models, obtaining the digging areas corresponding to the one or more other target three-dimensional models on the target surface of the target object based on the digging area corresponding to the current target three-dimensional model.

[0109] When there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, selecting the current target three-dimensional model from the one or more remaining target three-dimensional models is the same as the above embodiment and will not be repeated here.

[0110] The determining of the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target part of the current target three-dimensional model located inside the target object is the same as the above implementation manner and will not be repeated here.

[0111] Taking the current target three-dimensional model as the g-th target three-dimensional model as an example, the relevant parameters of the current target three-dimensional model include at least one of the following: one or more first target surfaces corresponding to the g-th target three-dimensional model, the relative distance between the g-th target three-dimensional model and each of the one or more first target surfaces corresponding to the g-th target three-dimensional model, the type of the g-th target three-dimensional model, and the rotation angle of the g-th target three-dimensional model.

[0112] The relative distance between the g-th target three-dimensional model and each of the one or more first target surfaces may be: the relative distance between the designated position of the g-th target three-dimensional model and each of the one or more first target surfaces. The designated position of the g-th target three-dimensional model may be any position in the g-th target three-dimensional model. For example, the designated position of the g-th target three-dimensional model may be the position of the center point of the g-th target three-dimensional model. This is only an exemplary description. The designated position of the g-th target three-dimensional model may also be other positions in the g-th target three-dimensional model, which is not limited in this application.

[0113] It can be understood that as long as the designated position of the g-th target three-dimensional model is the same as the designated position of one or more other target three-dimensional models, it is within the protection scope of the present application.

[0114] The type of the g-th target three-dimensional model is used to represent the geometric structure of the current target three-dimensional model.

[0115] The rotation angle of the g-th target three-dimensional model may include at least one of the following: a rotation angle of the g-th target three-dimensional model around a horizontal axis (i.e., an X-axis), a rotation angle of the g-th target three-dimensional model around a vertical axis (i.e., a Y-axis), and a rotation angle of the g-th target three-dimensional model around a vertical axis (i.e., a Z-axis). The horizontal axis, vertical axis, and vertical axis may be coordinate axes of a coordinate system of a three-dimensional design scene.

[0116] In one possible example, a method for determining the rotation angle of the g-th target three-dimensional model includes: rotating the one or more target three-dimensional models and the target object to obtain the rotated one or more target three-dimensional models and the target object; and using at least one of the rotation angles of the g-th target three-dimensional model around the horizontal axis (i.e., X-axis), the rotation angle around the vertical axis (i.e., Y-axis), and the rotation angle around the vertical axis (i.e., Z-axis) of the one or more rotated target three-dimensional models as the rotation angle of the g-th target three-dimensional model. The relative positions of the one or more rotated target three-dimensional models and the target object remain unchanged, and any first target surface of the one or more first target surfaces corresponding to the rotated g-th target three-dimensional model is on the same plane (i.e., XY plane) as the horizontal axis (i.e., X-axis) and the vertical axis (i.e., Y-axis) in the three-dimensional design scene coordinate system, and the any first target surface is perpendicular to the vertical axis (i.e., Z-axis) in the three-dimensional design scene coordinate system.

[0117] Taking the current target three-dimensional model as the g-th target three-dimensional model as an example, the relevant parameters of the current target three-dimensional model are the same as the relevant parameters of any other target three-dimensional model in one or more other target three-dimensional models, which may include: the one or more first target surfaces corresponding to the g-th target three-dimensional model are the same as the one or more second target surfaces corresponding to any other target three-dimensional model; the relative distance between the g-th target three-dimensional model and the one or more first target surfaces is the same as the relative distance between any other target three-dimensional model and the one or more first target surfaces; the type of the g-th target three-dimensional model is the same as the type of any other target three-dimensional model; the rotation angle of the g-th target three-dimensional model is the same as the rotation angle of any other target three-dimensional model. Among them, the method of determining the one or more second target surfaces corresponding to any other target three-dimensional model is the same as the method of determining the one or more first target surfaces corresponding to the g-th target three-dimensional model, and will not be repeated here.

[0118] Among them, the method for determining the rotation angle of any other target three-dimensional model may include: taking at least one of the rotation angle of any other target three-dimensional model around the horizontal axis (i.e., the X-axis) in the one or more rotated target three-dimensional models, the rotation angle of any other three-dimensional model around the longitudinal axis (i.e., the Y-axis), and the rotation angle of any other three-dimensional model around the vertical axis (i.e., the Z-axis) as the rotation angle of any other target three-dimensional model.

[0119] Optionally, taking the current target three-dimensional model as the g-th target three-dimensional model as an example, when the g-th target three-dimensional model corresponds to multiple first target surfaces and the multiple first target surfaces are parallel to each other, or the g-th target three-dimensional model corresponds to only one first target surface, the relevant parameters of the current target three-dimensional model are the same as the relevant parameters of any other target three-dimensional model in one or more other target three-dimensional models, and may include: the one or more first target surfaces corresponding to the g-th target three-dimensional model are the same as the one or more second target surfaces corresponding to any other target three-dimensional model; the relative distance between the g-th target three-dimensional model and the one or more first target surfaces is the same as the relative distance between any other target three-dimensional model and the one or more first target surfaces; the type of the g-th target three-dimensional model is the same as the type of any other target three-dimensional model; the rotation angle of the g-th target three-dimensional model around the horizontal axis (i.e., the X-axis) is the same as the rotation angle of any other target three-dimensional model around the horizontal axis (i.e., the X-axis); the rotation angle of the g-th target three-dimensional model around the vertical axis (i.e., the Y-axis) is the same as the rotation angle of any other target three-dimensional model around the vertical axis (i.e., the Y-axis).

[0120] Optionally, taking the current target three-dimensional model as the g-th target three-dimensional model as an example, when the g-th target three-dimensional model corresponds to multiple first target surfaces and the multiple first target surfaces are not parallel to each other, the relevant parameters of the current target three-dimensional model are the same as the relevant parameters of any other target three-dimensional model in one or more other target three-dimensional models, which may include: one or more first target surfaces corresponding to the g-th target three-dimensional model are the same as one or more second target surfaces corresponding to any other target three-dimensional model; the relative distance between the g-th target three-dimensional model and the one or more first target surfaces, and the relative distance between the g-th target three-dimensional model and any other target three-dimensional model The relative distance between the model and the one or more first target surfaces is the same; the type of the g-th target three-dimensional model is the same as the type of any other target three-dimensional model; the rotation angle of the g-th target three-dimensional model around the horizontal axis (i.e., X-axis) is the same as the rotation angle of any other target three-dimensional model around the horizontal axis (i.e., X-axis); the rotation angle of the g-th target three-dimensional model around the vertical axis (i.e., Y-axis) is the same as the rotation angle of any other target three-dimensional model around the vertical axis (i.e., Y-axis); the rotation angle of the g-th target three-dimensional model around the vertical axis (i.e., Z-axis) is the same as the rotation angle of any other target three-dimensional model around the vertical axis (i.e., Z-axis).

[0121] In this way, based on the target portion of the current target three-dimensional model located inside the target object, the digging area corresponding to the current target three-dimensional model is determined on the target surface of the target object; when there are one or more other target three-dimensional models with the same relevant parameters as the current target three-dimensional model in the one or more remaining target three-dimensional models, based on the digging area corresponding to the current target three-dimensional model, the digging areas corresponding to the one or more other target three-dimensional models on the target surface of the target object are obtained. In this way, after calculating the digging area corresponding to the current target three-dimensional model, the other target three-dimensional models with the same relevant parameters as the current target three-dimensional model can be determined through the relevant parameters of the current target three-dimensional model, and then the digging areas corresponding to the other target three-dimensional models can be obtained through the calculated digging areas corresponding to the current target three-dimensional model. There is no need to calculate the digging areas corresponding to the other target three-dimensional models, which improves the efficiency of obtaining the digging areas corresponding to the other target three-dimensional models.

[0122] Combine Figure 6 , this embodiment is described by way of example, including:

[0123] S601. Determine whether there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models. If there are one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, execute S602; if there are not one or more remaining target three-dimensional models with undetermined digging areas in the one or more target three-dimensional models, execute S606.

[0124] S602: Select a current target three-dimensional model from the one or more remaining target three-dimensional models.

[0125] S603 : Based on the target portion of the current target three-dimensional model located inside the target object, determine a digging area corresponding to the current target three-dimensional model on the target surface of the target object.

[0126] S604. Determine whether there are one or more other target three-dimensional models in the one or more remaining target three-dimensional models with the same relevant parameters as the current target three-dimensional model; if there are one or more other target three-dimensional models in the one or more remaining target three-dimensional models with the same relevant parameters as the current target three-dimensional model, execute S605; if there are not one or more other target three-dimensional models in the one or more remaining target three-dimensional models with the same relevant parameters as the current target three-dimensional model, return to execute S601.

[0127] S605 : Based on the digging area corresponding to the current target three-dimensional model, obtain the digging areas corresponding to the one or more other target three-dimensional models on the target surface of the target object, and return to execute S601 .

[0128] S606: Determine a geometric structure of the target surface after the holes are dug based on the dug areas corresponding to the one or more target three-dimensional models on the target surface of the target object.

[0129] S607 : Determine the geometric structure of the target object after the groove is formed based on the geometric structure of the target surface after the hole is dug.

[0130] S608: Render the target object based on the grooved geometric structure of the target object.

[0131] The obtaining, based on the digging area corresponding to the one or more other target three-dimensional models on the target surface of the target object, of the digging area corresponding to the current target three-dimensional model includes: determining, based on the relative position of the current target three-dimensional model and each other target three-dimensional model in the one or more other target three-dimensional models, an adjustment parameter corresponding to each other target three-dimensional model; and generating, on the target surface of the target object, a digging area corresponding to each other target three-dimensional model based on the adjustment parameter corresponding to each other target three-dimensional model and the digging area corresponding to the current target three-dimensional model.

[0132] Taking any other target 3D model among the one or more other target 3D models as an example, determining the adjustment parameter corresponding to each other target 3D model based on the relative position of the current target 3D model and each other target 3D model among the one or more other target 3D models may include: determining the relative distance and relative direction between the current target 3D model and the any other target 3D model based on the relative position of the current target 3D model and the any other target 3D model; and using the relative distance and relative direction between the current target 3D model and the any other target 3D model as the adjustment parameter corresponding to the any other target 3D model. The relative direction is the direction from the current target 3D model to the any other target 3D model.

[0133] Optionally, taking any other target three-dimensional model among the one or more other target three-dimensional models and the current target three-dimensional model as the g-th target three-dimensional model as an example, generating the digging area corresponding to each other target three-dimensional model on the target surface of the target object based on the adjustment parameters corresponding to each other target three-dimensional model and the digging area corresponding to the current target three-dimensional model may include: when there are multiple first target surfaces corresponding to the g-th target three-dimensional model and the multiple first target surfaces are parallel to each other, or when the g-th target three-dimensional model corresponds to only one first target surface, determining the first target position on each first target in the one or more first target surfaces based on the relative distance and relative direction between the g-th target three-dimensional model and the any other target three-dimensional model; generating a candidate digging area at the first target position of each first target surface that is the same as the digging area corresponding to the g-th three-dimensional model on each first target surface; rotating the candidate digging area around the vertical axis (i.e., the Z axis) based on the adjustment rotation angle corresponding to the any other target three-dimensional model to obtain the rotated candidate digging area; and using the rotated candidate digging area as the digging area corresponding to the any other target three-dimensional model on the target surface of the target object. The rotation angle of the rotated candidate digging area around the vertical axis (ie, the Z axis) is the same as the rotation angle of any other target three-dimensional model around the vertical axis (ie, the Z axis).

[0134] Among them, the adjusted rotation angle corresponding to any other target three-dimensional model can be: the difference between the angle of rotation of the g-th target three-dimensional model around the vertical axis (i.e., the Z axis) and the angle of rotation of any other target three-dimensional model around the vertical axis (i.e., the Z axis).

[0135] Optionally, taking any other target three-dimensional model among the one or more other target three-dimensional models and the current target three-dimensional model as the g-th target three-dimensional model as an example, based on the adjustment parameters corresponding to each other target three-dimensional model and the digging area corresponding to the current target three-dimensional model, generating a digging area corresponding to each other target three-dimensional model on the target surface of the target object may include: when there are multiple first target surfaces corresponding to the g-th target three-dimensional model and the multiple first target surfaces are not parallel to each other, determining a first target position on each first target surface among the multiple first target surfaces based on the relative distance and relative direction between the g-th target three-dimensional model and the any other target three-dimensional model; generating a candidate digging area that is the same as the digging area corresponding to the g-th three-dimensional model on each first target surface at the first target position of each first target surface; and using the candidate digging area as the digging area corresponding to any other target three-dimensional model on the target surface of the target object.

[0136] In this way, based on the relative position of the current target three-dimensional model and one or more other target three-dimensional models, the adjustment parameters corresponding to each other target three-dimensional model can be accurately obtained, and then the digging areas corresponding to the other target three-dimensional models can be generated through the adjustment parameters corresponding to each other target three-dimensional model and the digging areas corresponding to the current target three-dimensional model. There is no need to calculate the digging areas corresponding to each other target three-dimensional model. In this way, the efficiency of obtaining the digging areas corresponding to other target three-dimensional models can be improved.

[0137] In one possible embodiment, determining a digging area corresponding to the current target three-dimensional model on the target surface of the target object further includes: acquiring, from a storage area, the digging area corresponding to the current target three-dimensional model on the target surface of the target object. The digging area corresponding to the current target three-dimensional model on the target surface of the target object in the storage area may be a digging area corresponding to the current target three-dimensional model that was previously determined on the target surface of the target object.

[0138] The method of historically determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object is the same as the above-mentioned method of determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object, and will not be repeated here.

[0139] In one possible embodiment, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object may include: obtaining the digging area corresponding to the current target three-dimensional model on the target surface of the target object in a storage area; if the digging area cannot be obtained, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target portion of the current target three-dimensional model located inside the target object; if the digging area is obtained, using the obtained digging area corresponding to the current target three-dimensional model on the target surface of the target object as the digging area corresponding to the current target three-dimensional model on the target surface of the target object. Wherein, determining the digging area corresponding to the current target three-dimensional model on the target surface of the target object based on the target portion of the current target three-dimensional model located inside the target object is the same as the above embodiment and will not be repeated here.

[0140] In one possible embodiment, after determining the digging areas corresponding to the one or more target three-dimensional models on the target surface of the target object, the method further includes: adjusting the digging areas corresponding to the one or more target three-dimensional models to obtain adjusted digging areas corresponding to the one or more target three-dimensional models; and using the adjusted digging areas corresponding to the one or more target three-dimensional models as the final digging areas corresponding to the one or more target three-dimensional models. Taking any digging area corresponding to any target three-dimensional model as an example, the adjustment method can be: offsetting any digging area corresponding to any target three-dimensional model inward by a first distance to obtain an adjusted digging area corresponding to any target three-dimensional model. The first distance can be the area of ​​any digging area divided by the perimeter of the outer contour of any digging area.

[0141] In a possible implementation, the method further includes: generating a patch surface of the hole area corresponding to the current target three-dimensional model inside the target object based on the hole area corresponding to the current target three-dimensional model.

[0142] The current target 3D model may include one or more digging areas. Therefore, the digging area corresponding to the current target 3D model may also be referred to as the one or more digging areas corresponding to the current target 3D model. In other words, the digging area corresponding to the current target 3D model and the one or more digging areas corresponding to the current target 3D model have the same meaning.

[0143] Optionally, taking the current target three-dimensional model as the g-th target three-dimensional model and the k-th digging area corresponding to the g-th target three-dimensional model as an example, the generating of the complementary surfaces of one or more digging areas corresponding to the current target three-dimensional model inside the target object based on the digging area corresponding to the current target three-dimensional model may include: generating the elevation of the k-th digging area and the bottom of the k-th digging area inside the target object based on the k-th digging area corresponding to the g-th target three-dimensional model; and using the elevation of the k-th digging area and the bottom of the k-th digging area as the complementary surfaces of the k-th digging area. The elevation of the k-th digging area is perpendicular to the k-th digging area and does not overlap with multiple faces of the target object, and the bottom of the k-th digging area is parallel to the k-th digging area.

[0144] Optionally, still taking the current target three-dimensional model as the g-th target three-dimensional model and the k-th excavation area corresponding to the g-th target three-dimensional model as an example, generating the complementary surface of one or more excavation areas corresponding to the current target three-dimensional model inside the target object based on the excavation area corresponding to the current target three-dimensional model may include: generating the elevation of the k-th excavation area inside the target object based on the k-th excavation area among the one or more excavation areas corresponding to the g-th target three-dimensional model, when there are multiple excavation areas corresponding to the current target three-dimensional model and the multiple excavation areas are parallel to each other, or when there are multiple excavation areas corresponding to the current target three-dimensional model and the multiple excavation areas are not parallel to each other; and using the elevation of the k-th excavation area as the complementary surface of the k-th excavation area. Wherein, the elevation of the k-th excavation area is perpendicular to the k-th excavation area and does not overlap with multiple surfaces of the target object.

[0145] In this way, based on the cutout area corresponding to the current target 3D model, a patch surface corresponding to the cutout area of ​​the current target 3D model is generated within the target object. This prevents the internal structure of the wall from being exposed, improving the user's visual experience.

[0146] In one example, based on the digging area corresponding to the current target three-dimensional model, a complementary surface of the digging area corresponding to the current target three-dimensional model is generated inside the target object, including: based on the maximum vertical distance between the target part of the current target three-dimensional model located inside the target object and the target surface, and the digging area corresponding to the current target three-dimensional model, generating a vertical surface located inside the target object and perpendicular to the digging area corresponding to the current target three-dimensional model; based on the digging area corresponding to the current target three-dimensional model and the maximum vertical distance, generating a bottom surface located inside the target object; and using the vertical surface and the bottom surface as complementary surfaces of the digging area corresponding to the current target three-dimensional model.

[0147] It has been explained above that the digging area corresponding to the current target three-dimensional model may be one or more digging areas corresponding to the current target three-dimensional model, which will not be repeated here.

[0148] Still taking the current target three-dimensional model as the g-th target three-dimensional model and the k-th digging area corresponding to the g-th target three-dimensional model as an example, the generation of a facade located inside the target object and perpendicular to the one or more digging areas corresponding to the current target three-dimensional model based on the maximum vertical distance between the target portion of the current target three-dimensional model located inside the target object and the target surface and one or more digging areas corresponding to the current target three-dimensional model may include: moving the outer contour of the k-th digging area corresponding to the g-th target three-dimensional model into the target object by the maximum vertical distance between the target portion of the g-th target three-dimensional model located inside the target object and the target surface where the k-th digging area is located, to obtain a facade located inside the target object and perpendicular to the k-th digging area corresponding to the g-th target three-dimensional model (i.e., the facade is the facade of the k-th digging area). Wherein, the facade does not overlap with multiple surfaces of the target object.

[0149] Still taking the current target 3D model as the g-th target 3D model and the k-th digging area corresponding to the g-th target 3D model as an example, generating the bottom surface located inside the target object based on one or more digging areas corresponding to the current target 3D model and the maximum vertical distance may include: moving the k-th digging area corresponding to the g-th target 3D model into the target object by the maximum vertical distance between the target portion of the g-th target 3D model located inside the target object and the target surface where the k-th digging area is located, to generate the bottom surface of the k-th digging area located inside the target object. The bottom surface of the k-th digging area is parallel to the k-th digging area.

[0150] In this way, based on the maximum vertical distance between the target portion of the current target 3D model located inside the target object and the target surface, and the corresponding excavation area of ​​the current target 3D model, a vertical surface located inside the target object and perpendicular to the corresponding excavation area of ​​the current target 3D model is generated. Based on the corresponding excavation area of ​​the current target 3D model and the maximum vertical distance, a bottom surface located inside the target object is generated. This allows for a more accurate determination of the infill surface of the corresponding excavation area of ​​the current target 3D model.

[0151] In one example, when the current target three-dimensional model corresponds to multiple digging areas and the multiple digging areas are parallel to each other, or the current target three-dimensional model corresponds to multiple digging areas and the multiple digging areas are not parallel to each other, based on the digging areas corresponding to the current target three-dimensional model, a complementary surface of the digging area corresponding to the current target three-dimensional model is generated inside the target object, including: based on the maximum vertical distance between the target part of the current target three-dimensional model located inside the target object and the target surface, and the digging area corresponding to the current target three-dimensional model, generating a facade located inside the target object and perpendicular to the digging area corresponding to the current target three-dimensional model; and using the facade as the complementary surface of the digging area corresponding to the current target three-dimensional model.

[0152] The maximum vertical distance between the target part of the current target three-dimensional model located inside the target object and the target surface, and the digging area corresponding to the current target three-dimensional model, is used to generate a facade located inside the target object and perpendicular to the digging area corresponding to the current target three-dimensional model. This is the same as the above implementation method and will not be repeated here for the sake of brevity.

[0153] In one example, the method further includes: generating a patch surface of the hole area corresponding to one or more other target three-dimensional models inside the target object based on the adjustment parameters corresponding to each other target three-dimensional model and the patch surface of the hole area corresponding to the current target three-dimensional model.

[0154] Optionally, taking any other target three-dimensional model among the one or more other target three-dimensional models and the current target three-dimensional model as the g-th target three-dimensional model as an example, the generation of the complementary surface of the digging area corresponding to the one or more other target three-dimensional models inside the target object based on the adjustment parameters corresponding to each other target three-dimensional model and the complementary surface of the digging area corresponding to the current target three-dimensional model may include: when the g-th target three-dimensional model corresponds to multiple first target surfaces and the multiple first target surfaces are not parallel to each other, determining a second target position inside the target object based on the relative distance and relative direction between the g-th target three-dimensional model and any other target three-dimensional model; generating a candidate complementary surface that is identical to the complementary surface of the digging area corresponding to the g-th three-dimensional model at the second target position; and using the candidate complementary surface as the complementary surface of the digging area corresponding to any other target three-dimensional model.

[0155] Optionally, still taking any other target three-dimensional model among the one or more other target three-dimensional models and the current target three-dimensional model as the g-th target three-dimensional model as an example, generating the complementary surfaces of the digging areas corresponding to the one or more other target three-dimensional models inside the target object based on the adjustment parameters corresponding to each other target three-dimensional model and the complementary surfaces of the digging areas corresponding to the current target three-dimensional model may include: when there are multiple first target surfaces corresponding to the g-th target three-dimensional model and the multiple first target surfaces are parallel to each other, or when the g-th target three-dimensional model corresponds to only one first target surface, determining a second target position inside the target object based on the relative distance and relative direction between the g-th target three-dimensional model and the any other target three-dimensional model; generating a candidate complementary surface at the second target position that is identical to the complementary surface of the digging area corresponding to the g-th three-dimensional model; rotating the candidate complementary surface around the vertical axis (i.e., the Z axis) based on the adjustment rotation angle corresponding to the any other target three-dimensional model to obtain a rotated candidate complementary surface; and using the rotated candidate complementary surface as the complementary surface of the digging area corresponding to the any other target three-dimensional model. The rotation angle of the rotated candidate patch around the vertical axis (ie, the Z axis) is the same as the rotation angle of any other target three-dimensional model around the vertical axis (ie, the Z axis).

[0156] In this way, based on the adjustment parameters corresponding to each of the other target 3D models and the patched surface of the hole area corresponding to the current target 3D model, the patched surface of the hole area corresponding to the one or more other target 3D models is generated within the target object. Thus, after calculating the patched surface of the hole area corresponding to the current target 3D model, the patched surface of the hole area corresponding to the current target 3D model is used to obtain the patched surface of the hole area corresponding to the other target 3D models, eliminating the need to calculate the patched surface of the hole area corresponding to the other target 3D models, thereby improving the efficiency of obtaining the patched surface of the hole area corresponding to the other target 3D models.

[0157] In one example, the geometric structure of the target object after grooving is determined based on the geometric structure of the target surface of the target object after the hole is dug, including: determining the geometric structure of the target object after grooving based on the geometric structure of the target surface of the target object after the hole is dug and the complementary surface of the dug area corresponding to the one or more target three-dimensional models.

[0158] The method of determining the geometric structure of the target object after grooving based on the geometric structure of the target surface of the target object after digging and the complementary surface of the digging area corresponding to the one or more target three-dimensional models may include: using the geometric structure of one or more target surfaces of the target object after digging, the complementary surface of the digging area corresponding to the one or more target three-dimensional models, and one or more other surfaces of the target object as the geometric structure of the target object after grooving.

[0159] In this way, the post-grooving geometry of the target object is determined based on the post-digging geometry of the target surface and the patch surfaces of the digging areas corresponding to the one or more target 3D models. This allows the patch surfaces of the digging areas corresponding to the current target 3D model to be generated within the target object, preventing the internal structure of the wall from being exposed and improving the user's visual experience.

Figure 8 Figure 8 is a side anatomical view of the target object 801 and the target 3D model 802 after the groove is cut. It can be seen that the anatomical view of the target object 801 includes the target surface 806 (i.e., the surface excluding the cutout area 805 corresponding to the dotted line), other surfaces 807 to 809, and the vertical surface 804 and bottom surface 803 of the filler surface.
