[0021] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0022] The terminology used in one or more embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the scope of one or more embodiments of this application. The singular forms “a,” “the,” and “the” used in one or more embodiments of this application and in the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” used in one or more embodiments of this application refers to and includes any or all possible combinations of one or more associated listed items.

[0023] It should be understood that although the terms first, second, etc., may be used to describe various information in one or more embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first may also be referred to as second without departing from the scope of one or more embodiments of this application, and similarly, second may also be referred to as first. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0024] First, the terms and concepts involved in one or more embodiments of this application will be explained.

[0025] Boundary Representation: In computer-aided design, boundary representation is a method for storing information about how to construct a model based on its geometry, especially Eulerian topological boundaries. It is often abbreviated as BREP (Boundary Representation). A key characteristic of boundary representation is that the information describing the shape includes both geometric and topological information. Topological information describes the connections between vertices, edges, and faces on the shape, forming the "skeleton" of the object's boundary representation. The geometric information of the shape can be seen as the muscles attached to the "skeleton." For example, if a face of the shape lies on a curved surface, the data defining the equation of this surface is geometric information. Furthermore, the shape of edges, the position of vertices in three-dimensional space (coordinates of points), etc., are all geometric information. Generally, geometric information describes the size, dimensions, position, and shape of the shape. In boundary representation, the boundary information records in detail the geometric information of all geometric elements constituting the shape and their interconnected topological relationships, following a volume-face-loop-edge-point hierarchy.

[0026] Mesh is an important concept in digital modeling. A 3D model consists of multiple triangles combined at different angles (sharing sides or corners), with each outer triangle forming a triangular mesh. Mesh is generally a discrete result of BREP and is the data type required for rendering and display.

[0027] Extrusion modeling: A common method for 3D modeling, which involves drawing a cross-sectional shape of a model on a sketch plane and then specifying an extrusion height to create a three-dimensional shape.

[0028] Sketch: A sketch is a 2D graphic associated with a solid model. This function allows you to create a sketch plane on any desired surface, thus creating a sketch. The sketch incorporates the concept of "constraints," which can be modified to change the graphic within the sketch. Using the sketch tools, users can draw approximate curved outlines, and by adding precise constraint definitions, fully express their design intent. The created sketch can also be extruded, rotated, and manipulated using solid modeling tools to generate a solid model associated with the sketch. When a sketch is modified, the associated solid model is automatically updated.

[0029] Hard decoration: refers to the fixed and immovable decorations added to the surface or interior of a building in order to meet the structural, layout, functional and aesthetic needs of the house, in addition to the necessary infrastructure.

[0030] The conventional method for hard-surface extrusion modeling is: first construct a 2D sketch panel (i.e. Figure 1The boundary representation of the two-dimensional sketch panel shown is shown in the figure. Figure 2 The boundary shown is a schematic diagram; then according to Figure 2 The boundaries shown represent the protrusion height (i.e., stretch height) of each area marked in the diagram, one by one. Figure 2 The corresponding region in the boundary representation shown is stretched. For example... Figure 3 As shown, the left image includes a region with a protrusion height of 100, and the right image includes a region with a protrusion height of 200. Therefore, it is necessary to... Figure 2 The two regions shown were stretched twice to obtain the desired shape. Figure 3 The diagram on the right shows the final stretched shape.

[0031] because Figure 3 All the regions shown are topologically connected. Therefore, this extrusion modeling method requires a complete recalculation of all data for each region in the 2D sketch panel and boundary representation whenever the design needs to be modified or redrawn. As the design becomes more complex, the number of such regions increases, leading to significant computational resource consumption for each design and modification, slowing down the process and resulting in substantial performance overhead.

[0032] To address this, this application provides a method for processing design drawings, which can obtain multiple target regions to be stretched from a target two-dimensional sketch panel. Each target region includes a region identifier, a stretching height, and the coordinates of the vertices and edges that make up each target region. Then, based on the coordinates of the vertices and edges that make up the multiple target regions, the stretching height, and the corresponding region identifier, the multiple target regions are encoded to obtain the encoded representation of each target region. This allows for the determination of whether each target region is a newly drawn region based on its encoded representation, from a target cache space storing encoded representations of extruded shapes obtained from multiple regions drawn in the target 2D sketch panel. If the boundary representation of the extruded shape corresponding to the encoded representation of the first target region exists in the target cache space, the boundary representation of the extruded shape corresponding to the first target region can be directly obtained from the target cache space. Based on the boundary representation of the extruded shape corresponding to the first target region, a design drawing corresponding to the target 2D sketch panel can be generated, avoiding the need to re-extrude the first target region and reducing the computational resources occupied by extruding the first target region and calculating the boundary representation of the extruded shape obtained after extrusion. This saves performance overhead during the design and modification process of the design drawing corresponding to the target 2D sketch panel. Specifically, this application provides a method for processing design drawings, and also relates to a processing apparatus, electronic device, and computer-readable storage medium for design drawings, which will be described in detail in the following embodiments.

[0033] Figure 4 This is a schematic flowchart illustrating a method for processing design drawings, provided as an exemplary embodiment of this application. Figure 4 As shown, the method includes:

[0034] Step 410: Obtain multiple target regions to be stretched from the target 2D sketch panel. Each target region contains a region identifier, stretch height, and coordinates of the vertices and edges that make up the target region.

[0035] The target 2D sketch panel is used to draw 2D design drawings. The coordinates of the vertices and edges of each target area are drawn on this panel, which can be obtained based on the built-in 2D coordinate system. Moreover, each target area is automatically assigned a unique area identifier, and the extrusion height of each target area can be set by the designer. Figure 5 A schematic diagram of a two-dimensional hard-mounted sketch provided for an exemplary embodiment of this application. Figure 5 The 2D sketch of the hard decoration shown includes 18 target areas to be stretched. Each target area has a corresponding area label and stretch height (i.e., Figure 5 The convex values ​​shown) and the coordinates of the vertices and edges that make up the target area. The area identifier and the coordinates of the vertices and edges that make up the target area may not be displayed in the hard decoration 2D sketch, but can be obtained in the details of each target area (for example, clicking on each target area can display the details of each target area).

[0036] Step 420: Based on the coordinates of the vertices and edges that make up the multiple target regions, the stretching height, and the corresponding region identifiers, the multiple target regions are encoded to obtain the encoded representation of the multiple target regions.

[0037] The edge line can include at least one of line segments, circles, and arcs. A line segment can be represented by the coordinates of its starting point and ending point, a circle can be represented by the coordinates of its center point and its radius, and an arc can be represented by the coordinates of its center point, its radius, the coordinates of its starting point, and the coordinates of its ending point. Based on this, the embodiments of this application can encode line segments, circles, and arcs.

[0038] In some exemplary embodiments, when multiple target regions contain only edge lines, the multiple target regions are encoded based on the coordinates of the vertices and edge lines constituting the multiple target regions, the stretching height, and the corresponding region identifiers to obtain an encoded representation of the multiple target regions, including:

[0039] Based on the coordinates of the vertices that make up multiple target regions, the vertices of the multiple target regions are encoded to obtain the vertices of the multiple target regions;

[0040] When there are line segments in the edges that make up multiple target regions, the start-point and end-point codes of the line segments in the multiple target regions are obtained from the codes of the vertices of the multiple target regions.

[0041] Based on the start-point and end-point codes of line segments in multiple target areas and the preset line segment codes, the line segments in multiple target areas are encoded to obtain the line segment codes in multiple target areas;

[0042] Based on the line segment codes, region identifiers, stretching heights, and preset region codes in multiple target regions, each target region in the multiple target regions is encoded to obtain the encoded representation of each target region in the multiple target regions.

[0043] As an example, the vertex is encoded as x.toFixed(3)-y.toFixed(3), where x and y are the x and y coordinates of the vertex in the 2D sketch panel, respectively. ".toFixed(3)" is used to indicate that three decimal places should be retained. It should be understood that ".toFixed(3)" is only an illustrative example and does not constitute a limitation on the precision of vertex coordinates.

[0044] As an example, the encoding method for line segments is 'l2d'-(start point encoding)-(end point encoding), where 'l2d' is an example of a preset line segment code and does not constitute a limitation on the preset line segment code. The start point code is obtained by encoding the start point of the line segment according to the vertex encoding method, and the end point code is obtained by encoding the end point of the line segment according to the end point encoding method. The encoding method for each target region is 'f2d'-face.id-face.height-(encoding of all edges of the target region), where 'f2d' is an example of a preset region code, face.id is the region identifier of the target region, face.height is the stretch height of the target region, and all edges of the target region are all the line segments that make up the target region.

[0045] In some exemplary embodiments, when multiple target regions contain only edges and circles, each target region in the multiple target regions is encoded based on its line segment code, region identifier, stretching height, and preset region code to obtain an encoded representation of each target region in the multiple target regions, including:

[0046] When there are circles in the edges that make up multiple target regions, obtain the center point code of the circle in each target region from the code of the vertices of the multiple target regions, and determine the radius of the circle based on the coordinates of the edges that make up the multiple target regions;

[0047] Based on the center point encoding and radius of circles in multiple target regions and the preset circle code, the circles in multiple target regions are encoded to obtain the circle codes of multiple target regions;

[0048] Based on the line segment encoding, circle encoding, region identifier, stretching height, and preset region code of multiple target regions, each target region in the multiple target regions is encoded to obtain the encoded representation of each target region in the multiple target regions.

[0049] As an example, the circle encoding method is 'c2d'-(center point encoding)-radius.toFixed(3). The center point encoding can use the vertex encoding method, i.e., encoded as x.toFixed(3)-y.toFixed(3), where x and y are the horizontal and vertical coordinates of the center point in the 2D sketch panel, respectively. ".toFixed(3)" indicates that three decimal places should be retained, and 'c2d' is an example of a preset circle code. It should be understood that ".toFixed(3)" is only an illustrative example and does not constitute a limitation on the precision of the center point coordinates and radius. The encoding method for each target region is 'f2d'-face.id-face.height-(encoding of all edges of the target region), where 'f2d' is an example of a preset region code, face.id is the region identifier of the target region, face.height is the stretch height of the target region, and all edges of the target region are all the line segments and circles that make up the target region.

[0050] In some exemplary embodiments, when multiple target regions contain only edge lines and arcs, each target region in the multiple target regions is encoded based on its line segment code, region identifier, stretching height, and preset region code to obtain an encoded representation of each target region in the multiple target regions, including:

[0051] When there are arcs in the edges that make up multiple target regions, obtain the center point code, start point code, and end point code of the circle in each target region from the codes of the vertices of the multiple target regions, and determine the radius of the arc based on the coordinates of the edges that make up the multiple target regions;

[0052] Based on the center point encoding and radius of the arcs in multiple target regions and the preset arc code, the arcs in multiple target regions are encoded to obtain the arc codes of multiple target regions;

[0053] Based on line segment encoding, arc encoding, region identifier, stretching height, and preset region code of multiple target regions, each target region in the multiple target regions is encoded to obtain the encoded representation of each target region in the multiple target regions.

[0054] As an example, the arc encoding method is 'ca2d'-(center point encoding)-radius.toFixed(3)-start point encoding-end point encoding. The center point encoding, start point encoding, and end point encoding can all use vertex encoding, i.e., encoded as x.toFixed(3)-y.toFixed(3), where x and y are the x and y coordinates of the center point / arc start point / arc end point in the 2D sketch panel, respectively. ".toFixed(3)" indicates that three decimal places should be retained, and 'ca2d' is an example of a preset arc code. It should be understood that ".toFixed(3)" is merely an illustrative example and does not constitute a limitation on the precision of the center point coordinates, arc start point, arc end point, and radius.

[0055] As an example, the encoding method for each target region is 'f2d'-face.id-face.height-(encoding of all edges of the target region), where 'f2d' is an example of a preset region code, face.id is the region identifier of the target region, face.height is the stretch height of the target region, and all edges of the target region can include line segments and arcs.

[0056] In some exemplary embodiments, when multiple target regions simultaneously contain edges, circles, and arcs, each target region in the multiple target regions is encoded based on the line segment code, circle code, region identifier, stretching height, and preset region code of the multiple target regions to obtain the encoded representation of each target region in the multiple target regions, including:

[0057] When there are arcs in the edges that make up multiple target regions, obtain the center point code, start point code, and end point code of the circle in each target region from the codes of the vertices of the multiple target regions, and determine the radius of the arc based on the coordinates of the edges that make up the multiple target regions;

[0058] Based on the center point encoding and radius of the arcs in multiple target regions and the preset arc code, the arcs in multiple target regions are encoded to obtain the arc codes of multiple target regions;

[0059] Based on line segment encoding, circle encoding, arc encoding, region identifier, stretching height, and preset region code of multiple target regions, each target region in the multiple target regions is encoded to obtain the encoded representation of each target region in the multiple target regions.

[0060] As an example, the encoding method for each target region is 'f2d'-face.id-face.height-(encoding of all edges of the target region), where 'f2d' is an example of a preset region code, face.id is the region identifier of the target region, face.height is the stretch height of the target region, and all edges of the target region can include line segments, circles, and arcs.

[0061] In this embodiment, the encoding representation of the target region is used as the basis for whether the boundary representation of the extrusion model corresponding to the target region exists in the target cache space. If the boundary representation of the extrusion model corresponding to the target region exists in the target cache space, the boundary representation can be directly obtained, thereby saving the computing resources consumed by performing extrusion operations on the target region and calculating the relevant references for the extrusion model.

[0062] Step 430: Obtain the boundary representation of the extruded shape corresponding to the encoded representation of the first target region from the target cache space corresponding to the target 2D sketch panel.

[0063] The first target region comprises multiple target regions. The encoded representation of the boundary of the corresponding extruded shape exists in the target cache space. The target cache space stores the encoded representations of extruded shapes obtained from multiple regions drawn in the target 2D sketch panel. Specifically, the boundary representations of extruded shapes obtained from multiple regions drawn in the target 2D sketch panel stored in the target cache space are the encoded representations of extruded shapes obtained from multiple regions drawn in the target 2D sketch panel within a historical time period.

[0064] Figure 6 The embodiments provided in this application are based on Figure 5 The diagram shown illustrates the boundary representation of the extruded shape of each region obtained from the encoding of each region in the two-dimensional design sketch.

[0065] Step 440: Based on the boundary representation of the extruded shape corresponding to the first target region, generate the design drawing corresponding to the target two-dimensional sketch panel.

[0066] In some exemplary embodiments, if there are target regions among multiple target regions that have not been generated within a historical time period, an extrusion operation can be performed based on the encoded representation of these target regions to obtain the boundary representation of the corresponding extruded shape. Based on these newly generated boundary representations of extruded shapes and the boundary representations of extruded shapes stored in the target cache space, a design drawing corresponding to the template 2D sketch panel can be quickly generated. Specifically, generating the design drawing corresponding to the target 2D sketch panel based on the boundary representation of the extruded shape corresponding to the first target region includes:

[0067] When a second target region exists in multiple target regions, the second target region is stretched based on the encoded representation of the second target region to obtain the boundary representation of the stretched shape corresponding to the second target region. The second target region is a target region in multiple target regions whose encoded representation corresponds to a stretched shape that does not exist in the target cache space.

[0068] Based on the boundary representation of the extruded shape corresponding to the first target region and the boundary representation of the extruded shape corresponding to the second target region, the design drawing corresponding to the target two-dimensional sketch panel is generated.

[0069] Among them, stretching modeling is based on Figure 5 The two-dimensional model is generated by the shape and extrusion height of the two-dimensional area in the two-dimensional design sketch in the two-dimensional sketch panel.

[0070] This application embodiment utilizes the correspondence between the encoded representation and the boundary representation of the extrusion model to perform extrusion modeling only on target regions that do not exist in the target cache space, thus saving the computational overhead of extrusion modeling.

[0071] In some exemplary embodiments, since the boundary representations of the extruded shapes corresponding to the first target region and the second target region are both raw expressions of the region shapes, these expressions cannot be directly displayed to the user. Therefore, rendering operations are still required based on the data of these raw expressions. Specifically, based on the boundary representations of the extruded shapes corresponding to the first target region and the second target region, a design drawing corresponding to the target 2D sketch panel is generated, including:

[0072] The boundary representations of the extruded shapes corresponding to the first target region and the second target region are merged to obtain the boundary representations of the extruded shapes corresponding to multiple target regions.

[0073] Discretize the boundary representations of the extruded shapes corresponding to multiple target regions to obtain triangular facet data of the extruded shapes corresponding to multiple target regions;

[0074] The triangular facet data of the extruded shapes corresponding to multiple target areas are rendered to generate the design drawing corresponding to the target 2D sketch panel.

[0075] Figure 7 For the purposes of adopting the embodiments provided in this application, based on Figure 6 A schematic diagram of the boundary representation of the stretched shape obtained by merging the boundary representations of the stretched shapes of various regions. That is, the boundary representations of the stretched shapes corresponding to the first target region and the second target region are merged to obtain a schematic diagram of the boundary representations of the stretched shapes corresponding to multiple target regions. Figure 8For the purposes of adopting the embodiments provided in this application, based on Figure 7 A schematic diagram of the hard decoration design drawing obtained from the combined extrusion modeling rendering.

If the boundary representation of the stretched shape corresponding to the encoded representation of the target region exists in the target cache space, it can be directly obtained from the target cache space.

Figure 7 The diagram shows the boundary representation of the stretched shape in the hard decoration design.

Step s9 renders the triangular facet data for the stretched shapes corresponding to the target regions, generating... Figure 8 The hard decoration design drawing shown.

[0076] In some exemplary embodiments, to reduce the stretching operations on the two-dimensional design sketches corresponding to each design drawing, after stretching the second target region based on the encoded representation of the second target region to obtain the boundary representation of the stretched shape corresponding to the second target region, the method further includes:

[0077] Store the boundary representation of the extruded shape corresponding to the second target region into the target cache space.

[0078] The boundary representation of the extrusion model corresponding to the newly generated target area (i.e. the second target area) is stored in the target cache space, which can be directly obtained and used by the area in the next 2D design sketch that is consistent with the extrusion model corresponding to the second target area, reducing the number of extrusion operations and reducing the performance overhead during the extrusion operation process.

[0080] Step 910: Obtain multiple target areas to be stretched from the target 2D sketch panel.

[0081] Step 920: Encode multiple target regions to obtain encoded representations of multiple target regions.

[0082] Step 930: From the target cache space corresponding to the target 2D sketch panel, query the boundary representation of the extrusion model corresponding to the encoded representation of multiple target regions.

[0083] Step 940: Determine whether there is a boundary representation of the stretched shape corresponding to the encoded representation of the target region in the target cache space.

[0084] If there is no boundary representation of the stretched shape corresponding to the encoded representation of the target region in the target cache space, then proceed to step 950; otherwise, proceed to step 960.

[0085] Step 950: Based on the encoded representation of the target region, stretch the target region to obtain the boundary representation of the stretched shape corresponding to the target region.

[0086] Step 960: Obtain the boundary representation of the extruded shape corresponding to the target area.

[0087] If the target cache space contains the boundary representation of the extruded shape corresponding to the encoded representation of the target region, then the boundary representation of the extruded shape corresponding to the target region can be obtained directly from the target cache space.

[0088] Step 970: Merge the boundary representations of the extruded shapes corresponding to multiple target regions.

[0089] Step 980: Discretize the boundary representations of the extruded shapes corresponding to the merged target regions to obtain the triangular facet data of the extruded shapes corresponding to the target regions.

[0090] Step 990: Render the triangular facet data of the stretched shapes corresponding to multiple target areas to generate a design drawing.

[0091] Using the design drawing processing method provided in the embodiments of this application, multiple target regions to be stretched can be obtained from the target two-dimensional sketch panel. Each target region includes a region identifier, stretching height, and coordinates of the vertices and edges that make up each target region. Then, based on the coordinates of the vertices and edges that make up the multiple target regions, the stretching height, and the corresponding region identifier, the multiple target regions are encoded to obtain the encoded representation of each target region. This allows us to determine whether each target region is a newly drawn region based on the encoded representation of each target region. This can be done by storing the encoded representations of the extruded shapes obtained from multiple regions drawn in the target 2D sketch panel in the target cache space. If the boundary representation of the extruded shape corresponding to the encoded representation of the first target region exists in the target cache space, then the boundary representation of the extruded shape corresponding to the first target region can be directly obtained from the target cache space. Based on the boundary representation of the extruded shape corresponding to the first target region, the design drawing corresponding to the target 2D sketch panel can be generated. This avoids the need to re-extrude the first target region and reduces the computational resources occupied by extruding the first target region and calculating the boundary representation of the extruded shape obtained after extrusion, thereby saving performance overhead during the design and modification process of the design drawing corresponding to the target 2D sketch panel.
