[0046] Next, Figure 1 Various embodiments of the data processing method are described by taking the electronic device 1000 as an example of an implementation subject.

[0047] <Method Example>

[0048] Figure 2 The data processing method according to some embodiments is shown, and the data processing method is implemented by an electronic device, and the electronic device may specifically be the aforementioned electronic device 1000. The data processing method may include the following steps S210 to S220:

[0049] Step S210, obtaining first topological information and first geometric information of a first triangular mesh of a target geometric body, where the first geometric information represents shape features of the first triangular mesh.

[0050] In one embodiment of the present disclosure, the first topology information and the first geometry information may be obtained from a specified file stored in the electronic device, and the file type of the specified file may be a specified file type, for example, the file type of the specified file may be a UDO type.

[0051] Furthermore, the designated file may be created by the user on the electronic device 1000 , or may be automatically generated based on a target geometry drawn by the user through the electronic device 1000 , or may be transmitted to the electronic device 1000 from other electronic devices.

[0052] In the embodiment where the designated file is automatically generated based on the target geometric body drawn by the user through the electronic device 1000, the user may stretch the basic shapes such as rectangle, circle, triangle, ellipse to obtain the basic geometric body, and then perform Boolean operations (such as union, intersection, difference, etc.) on the basic geometric bodies such as cube, sphere, cylinder, etc. to form the target geometric body. For each basic geometric body in the target geometric body, it may be split into multiple first triangular meshes based on the corresponding rules, and then the designated file is generated based on the first topological information and first geometric information of the first triangular meshes of all the basic geometric bodies in the target geometric body.

[0053] For basic geometric bodies such as prisms, pyramids, and frustums composed of straight edges and planes, all planes can be converted into a combination of triangular facets by connecting a set of diagonal lines of polygons, and such basic geometric bodies can be converted into the first triangular mesh; for cylinders, cones, and frustums, the base circle (the base of the cone, the upper and lower bases of the cylinder and frustum) is divided into three equal parts, and then the three equal parts of the upper and lower bases are connected in a "zigzag" shape. The curve and surface information are attached to these corresponding faces, and such geometric shapes can be converted into the first triangular mesh; for a sphere, its inscribed tetrahedron is defined, and the sphere can be converted into the first triangular mesh; for other surfaces that can be represented as parametric surfaces (often from sweeping and lofting), uniform sampling can be used to sample the first vertex on the parametric surface and connect it, and sampling is preferentially performed on the surface boundary (also a curve) to obtain its boundary, and then points are evenly scattered inside the surface (there is no need to consider the area of ​​the connected triangles or the curvature of the surface, because the surface is recorded separately, and no information will be lost even if the sampling is poor), to obtain the first triangular mesh.

[0054] In one embodiment of the present disclosure, the first topological information includes first position data of two first vertices corresponding to the edges of the first triangular mesh, and second position data of three first vertices corresponding to the faces of the first triangular mesh, and the first geometric information includes first geometric data representing the shape of the edges of the first triangular mesh, and second geometric data representing the shape of the faces of the first triangular mesh.

[0055] In one embodiment, the first topological information may also include the identifiers and coordinate positions of the first vertices of the triangular mesh. Then, the first position data may include the identifiers corresponding to the two first vertices, and may also include the coordinate positions corresponding to the two first vertices, or may also include the identifiers and coordinate positions corresponding to the two first vertices; the second position data may include the identifiers corresponding to the three first vertices, and may also include the coordinate positions corresponding to the three first vertices, or may also include the identifiers and coordinate positions corresponding to the three first vertices.

[0056] In this embodiment, the shape of the surface of the first triangular mesh is the same as the shape of the curved surface where the first triangular mesh is located. The first geometric data and the second geometric data may be determined based on the geometric data of the curved surface where the first triangular mesh is located.

[0057] Specifically, the first geometric data may be a curve function representing the shape of the edge of the first triangular mesh, and the curve function may be a function representing a curve structure such as a line segment, a subdivision line, an arc, a parabola, an ellipse, a hyperbola, etc. The second geometric data may be a surface function representing the shape of the face of the first triangular mesh, and the surface function may be a function representing a plane, a subdivision face, a cylindrical face, a conical face, a spherical face, or other quadratic surfaces.

[0058] Step S220: generating and displaying a target geometric body in the interface according to the first topological information and the first geometric information.

[0059] In this embodiment, the target geometry is generated and displayed in the interface based on the first topological information and the first geometric information of the first triangular mesh of the target geometry, which can make the generated geometry more accurate. Moreover, the target geometry is stored based on the first topological information and the first geometric information of the first triangular mesh of the target geometry, which can improve storage efficiency and reduce occupied storage space.

[0060] In addition, in the process of displaying the target geometric body by the method of this embodiment, when operating and processing the plane and straight line boundaries, the calculation pressure will be smaller and it will be easier to parallelize, thereby improving the calculation efficiency.

[0061] In one embodiment of the present disclosure, a target geometric body is generated and displayed in an interface based on first topological information and first geometric information, including the following: subdividing the first triangular mesh according to the first topological information and the first geometric information to obtain second topological information and second geometric information of the second triangular mesh; generating and displaying the target geometric body in the interface based on the second topological information and the second geometric information.

[0062] In this embodiment, the triangular mesh may be subdivided at least once, and each subdivision process is the same. This embodiment only takes one subdivision process as an example for description.

[0063] Specifically, the first triangular meshes are subdivided into four second triangular meshes.

[0064] In one embodiment of the present disclosure, the step of obtaining the second topological information includes: obtaining third position data of the subdivision point on the corresponding edge based on the first position data; obtaining fourth position data of two second vertices corresponding to the edge of the second triangular mesh and fifth position data of three second vertices corresponding to the face of the second triangular mesh based on the first position data, the second position data and the third position data; and using the fourth position data and the fifth position data as the second topological information.

[0065] In this embodiment, a subdivision point may be taken from each edge of the first triangular mesh, and the third position data of the subdivision point may be obtained. The subdivision point and the first vertex of the first triangular mesh constitute the second vertex of the second triangular mesh.

[0066] Furthermore, for each first triangular mesh, every two subdivision points are connected, and each subdivision point is connected to the two first vertices located on the same edge in the second triangular mesh to obtain the edge of the second triangular mesh. Based on the first position data, the second position data and the third position data, the fourth position data representing the two second vertices corresponding to the edge of the second triangular mesh and the fifth position data representing the three second vertices corresponding to the face of the second triangular mesh can be obtained.

[0067] Furthermore, based on the fourth position data and the fifth position data, the second triangular mesh obtained can be used as the first triangular mesh, the fourth position data can be used as the first position data, and the fifth position data can be used as the second position data, and the first triangular mesh can continue to be subdivided. When the number of subdivisions reaches the set number of times, the fourth position data and the fifth position data finally obtained can be used as the second topological information.

[0068] The set number is a positive integer set by the user according to his actual needs. The larger the set number, the higher the calculation complexity and the higher the precision of the target geometry displayed in the interface; the smaller the set number, the lower the calculation complexity and the lower the precision of the target geometry displayed in the interface.

[0069] In one embodiment of the present disclosure, the method further includes: correcting the third position data according to the second geometric data.

[0070] Specifically, the third position data is corrected according to the second geometric data, including: determining the point on the surface of the first triangular mesh that is closest to the subdivision point according to the third position data, the second position data and the second geometric data, as the projection point of the subdivision point; and using the position data of the projection point as the third position data of the corresponding subdivision point.

[0071] In this embodiment, when the edge on the surface is subdivided, it cannot be guaranteed that the subdivision points still fall on the surface. If it is not corrected, the shape of the target geometric body obtained in the end will be distorted in the subdivision.

[0072] Through this embodiment, the third position data is corrected by using a projection method, that is, the subdivision point is corrected to its projection position on the original surface, and the projection process is to solve the point on the original surface closest to the subdivision point, and then use the projection point of the subdivision point to replace the corresponding subdivision point. In this way, the display accuracy of the target geometric body can be improved.

[0073] In one embodiment of the present disclosure, the step of obtaining the second geometric information includes: obtaining third geometric data representing the shape of the edge of the second triangular mesh and fourth geometric data representing the shape of the face of the second triangular mesh based on fourth position data, first geometric data and second geometric data; and using the third geometric data and fourth geometric data as the second geometric information.

[0074] In this embodiment, when the first second triangular mesh is obtained by subdividing the first first triangular mesh, the shape of the surface after the subdivision of the first second triangular mesh is the same as the shape of the surface of the first first triangular mesh. Therefore, the fourth geometric data representing the shape of the surface of the first second triangular mesh is the same as the second geometric data representing the shape of the surface of the first second triangular mesh.

[0075] Furthermore, when the first edge of the first second triangular mesh coincides with the first edge of the first first triangular mesh, the first geometric data representing the shape of the first edge of the first first triangular mesh can be used as third geometric data representing the shape of the first edge of the first second triangular mesh.

[0076] Furthermore, when the second edge of the first second triangular mesh does not overlap with all edges of the first first triangular mesh, third geometric data representing the shape of the second edge of the first second triangular mesh can be obtained based on the fourth position data and the second geometric data.

[0077] In this embodiment, the target geometric body is generated and displayed in the interface according to the second topological information and the second geometric information, which can improve the display accuracy of the target geometric body and enhance the display effect of the target geometric body.

[0078] In one embodiment of the present disclosure, after executing step S220, the method further includes: performing Laplace smoothing processing on the generated target geometric body.

[0079] Through this embodiment, the displayed target geometry can be made smoother.

[0080] Figure 3 A flow chart showing an example of a data processing method according to an embodiment of the present disclosure is shown as follows: Figure 3 As shown, the data processing method may include the following steps:

[0081] Step S301: acquiring first topological information and first geometric information of a first triangular mesh of a target geometric body, wherein the first geometric information represents shape features of the first triangular mesh.

[0082] Step S302: Obtain third position data of a subdivision point on a corresponding edge according to the first position data.

[0083] Step S303: determining the point on the surface of the first triangular mesh that is closest to the subdivision point according to the third position data, the second position data and the second geometric data as the projection point of the subdivision point.

[0084] Step S304: Using the position data of the projection point as the third position data of the corresponding subdivision point.

[0085] Step S305, obtaining fourth position data representing two second vertices corresponding to the edge of the second triangular mesh and fifth position data representing three second vertices corresponding to the face of the second triangular mesh based on the first position data, the second position data and the third position data.

[0086] Step S306, determining whether the number of subdivision processing reaches the set number, if yes, executing step S308; if not, executing step S307.

[0087] Step S307: Use the obtained second triangular mesh as the first triangular mesh, use the fourth position data as the first position data, and use the fifth position data as the second position data.

[0088] Step S308, obtaining third geometric data representing the shape of the edge of the second triangular mesh and fourth geometric data representing the shape of the surface of the second triangular mesh according to the fourth position data, the first geometric data and the second geometric data.

[0089] Step S309: Use the fourth position data and the fifth position data as second topological information, and use the third geometric data and the fourth geometric data as second geometric information.

[0090] Step S310: Generate and display a target geometric body in the interface according to the second topological information and the second geometric information.
