[0028] This application first proposes a method for adjusting a 3D model, which is applied to a terminal device. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating the first embodiment of the model adjustment method provided in this application. Figure 2 This is a schematic diagram illustrating the adjustment of the shape of an embodiment of the model provided in this application. For example... Figure 1 As shown, the model adjustment method includes the following steps:

[0029] Step S11: Obtain the model file, which includes the model shape.

[0030] Specifically, the model file includes geometric data, topological data, texture data, material information, and attribute data of the 3D model. The model file describes the shape, appearance, material, and position and orientation of the 3D model in space. The model shape describes the appearance, internal structure, and composition of the components indicated by the 3D model. The model shape can be, but is not limited to, composed of parameters related to the positions and connections of vertices, edges, and faces. For example, such as... Figure 2 As shown in A, the original model file contains a model shape with rich surface features, and the complex internal circuits and structures can be obtained by adjusting the model file.

[0031] Step S12: Analyze the model shape to obtain several shells of the model shape.

[0032] Specifically, after obtaining the model shape from the model file, the model shape is parsed. Understandably, the shape of a 3D model typically includes multiple structures, with the shell in the model shape representing the shell corresponding to each structural component. For example, when the model shape is a reducer, it may be composed of at least one structure such as a housing, gears, a motor, or fasteners.

[0033] At this point, the model adjustment method in this embodiment can obtain the shape parameters of each structure in the model shape by parsing the model shape. The shape parameters are used to describe the positions of the vertices, edges, and faces of the structure in the internal coordinate system of the model file. Therefore, the shells of all structures can be defined through the shape parameters. When parsing the model shape, the parameters of the model file can be processed using 3D modeling software, such as CATIA, AutoCAD, Inventor, SolidWorks, etc.; or, the parameters of the model file can be filtered and calculated using algorithms to obtain several shells of the model shape.

[0034] Understandably, after parsing the model shape in the original model file, the surface contours of the model shape are closed, thus concealing the previously exposed surface features and only revealing the contour surface shape on the shell, such as... Figure 2 As shown in B. At this point, when the shells are cut or cross-sectionally analyzed, technical details such as the internal structure, oil passages, and electrical wiring can still be seen inside the shells.

[0035] Step S13: Calculate the volume of all shells of the model shape, and take the shell with the largest volume as the outermost shell.

[0036] After obtaining all the shells of the model shape, all shells are traversed to calculate the volume of each traversed shell. After obtaining the volumes of all shells, the shell with the largest volume is found by sorting, and this shell with the largest volume is used as the outermost shell of the model shape. Understandably, in the 3D model of a mechanical part, the outermost shell usually occupies the largest space. Therefore, the model adjustment method in this embodiment can accurately locate the outermost shell of the model shape by finding the shell with the largest volume.

[0037] Step S14: Fill the outermost shell with internal material to obtain the adjusted model shape.

[0038] After obtaining the outermost shell of the model shape, the outermost shell is filled internally, making its interior a solid structure. Since the outermost shell does not contain other structures, when the filled outermost shell is output to obtain the adjusted model shape, the output model shape does not include the complex internal structure and technical details. The adjusted model shape only presents a model with an outer shell structure, which meets the requirements of model information confidentiality and specific display needs. For example... Figure 2 As shown in C and 2D, Figure 2 C represents the adjusted shape of the model. Figure 2 When the model shape of C is sectioned, it is obtained Figure 2 D, the cross-section of the model shape only shows the internal solid structure, and the original internal structure and details cannot be seen.

[0039] Therefore, in this embodiment, the model adjustment method obtains a model file, which includes the model shape; parses the model shape to obtain several shells; calculates the volume of all shells of the model shape, and takes the shell with the largest volume as the outermost shell; and fills the outermost shell to obtain the adjusted model shape. Thus, the model adjustment method of this embodiment can automatically identify and process the outermost shell in a 3D model, thereby reducing the tedious steps in traditional manual adjustment. The inner part of the outermost shell in the adjusted model shape is filled, hiding the original internal structure. When users perform operations such as cutting and separating the adjusted 3D model, the original technical details will not be leaked, ensuring that the adjusted model shape meets the requirements of data security and confidentiality. The operation is simple, significantly reducing labor costs and improving the efficiency of model adjustment.

[0040] In some embodiments, see Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the model adjustment method provided in this application. Figure 3 As shown, in this embodiment, the model adjustment method includes the following steps:

[0041] Step S21: Obtain the model file, which includes the model shape.

[0042] Step S21 is similar to step S11 above, and will not be repeated here.

[0043] Step S22: Analyze the model shape to obtain the wireframe data of the model shape.

[0044] Specifically, when parsing the model shape, several model parameters that make up the model shape can be obtained. By querying and / or filtering the model parameters, wireframes, contour lines, boundary lines of internal structures, or intersections between different geometric features in the model shape can be obtained, so that the relevant data of all lines in the model shape can be used as wireframe data.

[0045] In a possible implementation, wireframe data can be obtained by operating on the model parameters using functions or algorithms. For example, the `get_all_wires` function can be used to parse the topology of the model shape, and valid wireframes can be found and filtered from the parsed topology to obtain wireframe data. Alternatively, wireframe data of the model shape can be obtained using segmentation tools or AI-based image recognition methods; no specific limitations are imposed here.

[0046] Step S23: Convert the wireframe data into several curved surfaces to obtain several shells.

[0047] Specifically, wireframe data can include one or more connected lines, which can be, but are not limited to, outlines, boundary lines of internal structures, or intersections between different geometric features. The lines in the wireframe data can form one or more closed loops. For example, when defining a rectangular surface, the wireframe can be composed of a closed loop of four lines connected sequentially, end to end, to form the outline of a rectangle.

[0048] The model adjustment method of this embodiment, after obtaining wireframe data, can determine the geometric shape of the generated surface based on the indicated wireframe shape and position in the wireframe data. For example, when the wireframe includes planar polygons, such as triangles or rectangles, the surface generated from the corresponding wireframe data can be understood as the corresponding polygonal surface within the plane. When the wireframe includes a closed contour composed of curves, the surface generated from the corresponding wireframe data may be part of a curved surface, such as generating a part of a simple curved surface like a cylinder or sphere from a circular wireframe, or generating a complex curved surface from a complex curve.

[0049] After obtaining wireframe data, each edge and vertex in the wireframe is used as the boundary elements of newly generated surfaces. The relationships between these boundary elements are established within the pre-defined topology of the model, resulting in the creation of several surfaces based on the wireframe data. Each surface can serve as the shell of a corresponding structure within the model shape. Therefore, by combining the wireframe data of the model shape into several surfaces, the resulting surfaces are closed, thus obtaining the shells of all structures within the model shape. Since the shells of structures are obtained through closed surfaces composed of contour lines, subtle structures not belonging to the contour lines are hidden, but the internal space of the shell still contains several complex structures.

[0050] In possible implementations, wireframe data can be combined into multiple surfaces using the wire_to_face function, or multiple surfaces can be combined using surface reconstruction algorithms, such as planar subdivision surface techniques or mesh optimization algorithms, without being specifically limited here.

[0051] Step S24: Calculate the volume of all shells of the model shape, and take the shell with the largest volume as the outermost shell.

[0052] Step S25: Fill the outermost shell with internal material to obtain the adjusted model shape.

[0053] Steps S24-S25 are similar to steps S13-S14 above, and will not be repeated here.

[0054] In this embodiment, the model adjustment method analyzes the model shape to obtain wireframe data, then converts the wireframe data into several curved surfaces to obtain several shells. Therefore, by decomposing the complex model shape into basic line structures and converting them into curved surfaces to obtain the corresponding shells, the accuracy of the model analysis is ensured. This allows for subsequent volume calculations of the shells and the concealment of internal technical details, thereby improving overall work efficiency.

[0055] In some embodiments, after step S23 or after step S12, the method further includes converting a plurality of shells into solids.

[0056] Specifically, the shells obtained after step S23 or step S12 are composed of curved surfaces. These curved surfaces are actually collections of discontinuous line elements, and their internal regions cannot be directly determined, thus making it impossible to directly calculate the volume of the shells. Therefore, the model adjustment method in this embodiment converts the shells into solids, giving the converted shells closed boundaries, thus allowing the volume of the shells to be obtained by calculating their internal regions.

[0057] In a possible implementation, the step of converting several shells into a solid may further include: performing geometric closure processing on the shells; and structurally reorganizing the closed shells to organize them into a solid data structure. Specifically, the processing steps include, but are not limited to, finding and filling holes, connecting discontinuous edges, and generating missing faces, so that the shells form a geometrically closed whole with a defined internal space. The structural reorganization step may, but is not limited to, integrating and storing the geometric and topological elements of the shells according to the definition of a solid to establish a solid data structure. In other implementations, the above-mentioned step of converting several shells into a solid can be implemented through Boolean operations of 3D modeling software, functions for stitching discontinuous geometric elements into a whole, programming interfaces or scripts, or by creating missing faces or edges and adjusting the position and shape of geometric elements; no specific limitations are made here.

[0058] Optionally, in one embodiment, the model file is in a standard exchange format. Alternatively, in another embodiment, after step S11 or S21, the model adjustment method further includes converting the model file to a standard exchange format.

[0059] Specifically, the Standard for the Exchange of Product Model Data (STEP) is used to exchange product design data between different 3D modeling software to ensure data accuracy and consistency. The original format of the model file can be, but is not limited to, step (stp), catpart, stl, wrl, etc. The format of the model file is related to the model type, the model description information, the modeling software used, etc., and is not specifically limited here.

[0060] This embodiment uses model files in a standard exchange format, or converts non-standard exchange formats to a standard exchange format when necessary, to ensure that the model shape can completely and accurately describe the product's geometry, topology, dimensional tolerances, material properties, and other comprehensive information. It can be used for lossless data transmission and storage of basic component models or multi-component assembly models, offering wide applicability and strong versatility. By using a model file in a standard exchange format as the base data format for subsequent model processing, this embodiment ensures efficient, stable, and accurate operation of the entire processing flow, improving the reliability of the model adjustment method.

[0061] In some embodiments, after step S13 or step S24, the model adjustment method of this embodiment further includes: repairing the holes in the outermost shell to obtain a closed outermost shell.

[0062] Specifically, in possible implementations, after the model file undergoes format conversion—for example, converting it from the initial design format to the common STP format, or to a format required for importing into specific analysis software—data loss may occur in the converted model file due to differences in data parsing and storage methods between different file formats. This data loss is reflected in the outermost entity, potentially manifesting as holes on the entity's surface. Alternatively, because internal components have been removed from the outermost shell, some areas of the outermost shell may exhibit holes.

[0063] Therefore, the model adjustment method in this embodiment can repair the holes in the outermost shell when they exist, thus obtaining a closed outermost shell. The outermost shell has a clearly defined internal region, which facilitates subsequent internal filling of the outermost shell.

[0064] The steps for repairing the holes in the outermost shell may further include: traversing and searching for holes in the outermost shell; obtaining the boundary curve of each hole; calculating the spline surface of each hole according to the constraint energy equation and / or penalty function method; and, when the spline surface meets the tolerance standard, performing boundary trimming on the spline surface to make the hole boundary in the outermost shell disappear, thus repairing the hole. Alternatively, the steps for repairing the holes in the outermost shell may include: identifying the holes in the outermost shell; and removing the faces or edges that form the holes to obtain a closed outermost shell.

[0065] Therefore, the model adjustment method in this embodiment obtains a closed outermost shell by repairing the holes in the outermost shell, which can ensure the integrity and sealing of the outermost shell, guarantee the effect of subsequent filling of the outermost shell, and improve the reliability of the model adjustment method.

[0066] In some embodiments, see Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the model adjustment method provided in this application. Figure 4 As shown, the model adjustment method includes the following steps:

[0067] Step S31: Obtain the model file, which includes the model shape.

[0068] Step S32: Analyze the model shape to obtain several shells of the model shape.

[0069] Step S33: Calculate the volume of all shells of the model shape, and take the shell with the largest volume as the outermost shell.

[0070] Steps S31-S33 are similar to steps S11-S13 above, and will not be repeated here.

[0071] Step S34: Use 3D modeling software to close the outermost shell with a curved surface to obtain the adjusted model shape.

[0072] Specifically, when filling the outermost shell, the shell can be filled by using the surface closure function of 3D modeling software. Surface closure specifically includes: identifying the closed boundary of the outermost shell to determine the internal region of the closed boundary; and adjusting and optimizing the topology of the internal region so that the outermost shell forms a closed solid in terms of topology.

[0073] By using 3D modeling software to close curved surfaces, the structural integrity of the model can be ensured, the design efficiency and accuracy of the model can be improved, the operation is convenient and efficient, it can meet the needs of complex shape design, and improve the overall quality of the model.

[0074] In this embodiment, the model adjustment method uses 3D modeling software to create a curved surface closure on the outermost shell, connecting the surfaces of the outermost shell into a complete closed surface. The interior of the outermost shell is filled and becomes a solid, hiding the original internal structure. When the user performs operations such as cutting and separating the adjusted 3D model, the original technical details will not be disclosed. This ensures that the adjusted model shape meets the requirements of data security and confidentiality. The method is simple to operate, significantly reduces labor costs, and improves the efficiency of model adjustment.

[0075] In some embodiments, see Figure 5 , Figure 5 This is a flowchart illustrating the fourth embodiment of the model adjustment method provided in this application. Figure 5 As shown, after step S34, the model adjustment method further includes:

[0076] Step S41: Read the script file of the 3D modeling software.

[0077] Specifically, steps S31-S34 can all be executed in 3D modeling software; alternatively, the steps of parsing the model shape to obtain wireframe data, converting the wireframe data into several surfaces to obtain several shells, calculating the volume of all shells of the model shape, taking the shell with the largest volume as the outermost shell, and filling the outermost shell to obtain the adjusted model shape can all be executed in 3D modeling software. At this time, the commands and instructions used during the execution of the above steps can be recorded using the 3D modeling software to obtain a script file.

[0078] Step S42: Convert the script file into a code file.

[0079] After reading the script file, the commands and instructions within it are converted into code files in a preset format. These code files can be written in languages ​​such as Python, Java, and C#. Understandably, the code files can perform geometric calculations using different databases to achieve the aforementioned operations such as parsing the model file, extracting line segment data, and constructing surfaces.

[0080] Step S43: Package the code file to obtain an executable file and adjust the model using the executable file.

[0081] The code files are encapsulated and integrated into the executable file, so that when users need to adjust the model, they can hide the internal structure of the model shape with one click through the executable file, so that the model only has the outermost shell. The operation is simple.

[0082] Furthermore, unlike related technologies that require engineers to possess specialized and in-depth modeling software skills, typically necessitating a training period of up to three months, which is costly, the solution in this application integrates complex modeling operations into code files. Complex operations are completed through executable files, significantly improving model adjustment efficiency and reducing labor costs.
