[0031] The present disclosure will be further described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0032] In addition, for better illustration of the present disclosure, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can be implemented without some specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present disclosure.

[0033] Figure 1 is a schematic flowchart of uploading a three-dimensional (3D) model according to an embodiment of the present disclosure, as Figure 1 shown. To upload a 3D gusset plate, it is necessary to first create a 3D model in 3D model rendering software, then export the 3D model, and then upload it from the background. Since many gusset plate models are relatively simple (without engraving, etc.), if such a simple model is created according to the above method, it will result in complex operations and high costs for creating models in 3D model rendering software; the overall process is relatively long and the efficiency is low.

[0034] Figure 2 is a schematic flowchart of a mesh model modeling method according to an embodiment of the present disclosure, as Figure 2 shown. The method includes:

[0035] S201. Generate geometric data according to the sectional profile and lofting path of the object;

[0036] S202. Obtain mesh model data according to the geometric data;

[0037] S203. Generate a mesh model configuration file according to the mesh model data;

[0038] S204. Render the mesh model of the object according to the mesh model configuration file.

[0039] In the embodiments of the present disclosure, the cross-sectional profile may include two-dimensional graphics, such as regular two-dimensional graphics like squares, rectangles, triangles, trapezoids, etc. and irregular two-dimensional graphics. The present disclosure does not limit this. The lofting path may include functions, such as linear functions, quadratic functions, power functions, exponential functions, trigonometric functions, etc. The present disclosure does not limit this. Lofting is a technique for converting 2D graphics into 3D models. By interpolating between two or more 2D cross-sections, a continuous 3D shape can be generated. Through lofting, a two-dimensional object can be used as a cross-section and lofted along a certain path to form a three-dimensional object. For example, as Figure 3 shown, the cross-sectional profile of a square in the y0z plane of a three-dimensional coordinate system, along the lofting path in the coordinate system, a quadrangular prism can be obtained.

[0040] In the embodiments of the present disclosure, the cross-sectional profile and the lofting path can be generated and created through computer-aided design (CAD) tools. The cross-sectional profile and the lofting path of geometric graphics can be obtained by parsing a two-dimensional image configuration file (cad profile). For example, the cross-sectional profile of a triangle and the lofting path of x = y can be obtained by parsing from a cad profile. Each cad profile may include the cross-sectional profile and the lofting path of a geometric graphic.

[0041] In the embodiments of the present disclosure, lofting can be performed in the background of the platform according to the cross-sectional profile and the lofting path of two-dimensional geometric graphics to generate three-dimensional geometric graphics. Geometric data, such as the length, width, height, and coordinates of each vertex of the geometric body, can be obtained based on the three-dimensional geometric graphics. The material data of the three-dimensional geometric graphics can be obtained. The material data may include the material selected by the user at the front end of the platform or the default material of the platform, such as marble, wood board, metal, etc.

[0042] In the embodiments of the present disclosure, a conversion tool in the platform background can be used to obtain mesh model data based on the three-dimensional geometric graphics rendered with the material. Mesh model data can also be referred to as polygon mesh data, which is a data structure used in computer graphics to model various irregular objects. Intuitively, the surfaces of objects in the real world are all composed of curved surfaces; while in the computer world, since only discrete structures can be used to simulate continuous things in reality. Therefore, the curved surfaces in the real world are actually composed of countless small polygon patches in the computer. Mesh model data may include multiple two-dimensional polygons (patches) with aligned corners. The patches can be pentagons, quadrilaterals, triangles, etc. The present disclosure does not limit this.

[0043] In the embodiments of the present disclosure, the mesh model data may include the coordinates of the vertices of each patch, and a mesh model may be composed of multiple patches. For example, for mesh model data with triangular patches, the whole is a set of all triangular patches. In the set, each triangular patch includes three vertices, and each vertex can be represented by (x, y, z) coordinates. For example, a mesh model data can be expressed as {mesh1: [p1(x1, y1, z1), p2(x2, y2, z2), p3(x3, y3, z3)]; mesh2: [p4(x4, y4, z4), p5(x5, y5, z5), p6(x6, y6, z6)]; mesh3: [p7(x7, y7, z7), p8(x8, y8, z8), p9(x9, y9, z9)];...;}, where mesh represents the patch of the model, p represents the vertex of each patch, and (x, y, z) represents the specific coordinates of the vertex.

[0044] In the embodiments of the present disclosure, according to the mesh model data, a data format conversion tool in the platform background can be called to convert it into a mesh model configuration file. If the mesh model data does not meet the format requirements of the mesh model rendering tool, the mesh model cannot be directly rendered based on the mesh model data. In this case, the data format conversion tool can be used to convert the mesh model data into a mesh model configuration file in a standard format.

[0045] In the embodiments of the present disclosure, a mesh model rendering tool in the platform background can be called to render a mesh model according to the mesh model configuration file.

[0046] According to the embodiments of the present disclosure, a mesh model can be automatically generated based on a two-dimensional profile and a lofting path. Compared with the cumbersome operation of gradually creating a three-dimensional mesh model using three-dimensional design software, the generation process of the three-dimensional mesh model is simplified, and the efficiency of generating the three-dimensional mesh model is improved.

[0047] Figure 4 It is a schematic flowchart of a mesh model modeling method according to another embodiment of the present disclosure. This method may include one or more features of the above-mentioned mesh model modeling method. In one implementation, as Figure 4 shown, S201 generates geometric data according to the profile and lofting path of the object, including:

[0048] S401. Obtain the profile of the object according to a computer-aided design file (cad profile);

[0049] S402. Loft the profile along the lofting path to generate the geometric data.

[0050] In the embodiments of the present disclosure, the cad profile can be input into the background of the platform, and the parsing tool in the background can parse the cross-sectional profile and lofting path included therein from the cad profile. The lofting path can include the direction of the path and the length of the path, etc. The direction of the path can be determined according to the cross-sectional profile. For example, the normal direction of the two-dimensional graph of the cross-sectional profile can be used as the direction of the lofting path. The length of the path can be determined according to the height of the geometric body in the cad profile, or can be determined according to the height of the geometric body set by the user on the platform.

[0051] In the embodiments of the present disclosure, a three-dimensional model can also be created in the graphic design module of the platform, and the cad profile of the three-dimensional model can be generated. The parsing tool in the background can parse the cross-sectional profile and lofting path from the generated cad profile of the three-dimensional model.

[0052] In the embodiments of the present disclosure, lofting can be performed according to the cross-sectional profile and the lofting path to obtain the data of the geometric figure. For example, according to the circular cross-sectional profile and the lofting path of x = 0 parsed from the cad profile, the data of the geometric figure of the cylinder can be lofted.

[0053] In the embodiments of the present disclosure, the geometric figure can not be directly rendered, but the lofting calculation can be performed in the background to obtain the various data of the geometric figure, such as the geometric figure function representation, the various parameters of the geometric figure such as length, width, height, etc.

[0054] According to the embodiments of the present disclosure, the various data of the geometric figure can be obtained through the computer-aided design file, which is convenient for generating the mesh model data according to the geometric data of the geometric figure.

[0055] In one implementation, as Figure 4 shown, S202 obtaining the mesh model data according to the geometric data includes:

[0056] S403, in response to the material selection operation, obtaining the material data of the selected material;

[0057] S404, transforming the geometric data to obtain the patch data, normal data and texture (UV) data.

[0058] In the embodiments of the present disclosure, the material of the three-dimensional model can include the combination of the visible attributes on the surface of the three-dimensional model, and these visible attributes can include the color, pattern, smoothness, transparency, reflectivity, refractive index, luminosity, etc. of the surface. The material can be stored in the material library of the platform, and in response to the user's material selection operation, the material data is transmitted to the background.

[0059] In the embodiments of the present disclosure, geometric data can be converted into mesh model data according to a conversion tool in the background. The mesh model data may include patch data, normal data, texture (UV) data, etc. The patch data may include the type of the patch, the coordinates of each vertex of the patch, etc.; the normal data may include surface normal vectors, vertex normal vectors, etc.; the texture data may include the coordinate representation of the texture bound to the geometry, specifically including texture mapping and projection methods, etc. The projection methods may include planar projection, spherical projection, cylindrical projection, cubic projection, etc.

[0060] According to the embodiments of the present disclosure, the data of a three-dimensional geometric figure can be converted into its corresponding mesh model data, which is convenient for rendering the three-dimensional mesh model.

[0061] In one implementation, as Figure 4 shown, the mesh model configuration file includes a shape file, a material file, and a mapping file. S203 generates a mesh model configuration file according to the mesh model data, including:

[0062] S405. Obtain the shape file according to the patch data, normal data, and texture data;

[0063] S406. Obtain the material file according to the material data;

[0064] S407. Generate a mapping configuration file according to the corresponding relationship between the material data and at least one of the patch data, the normal data, and the texture data.

[0065] In the embodiments of the present disclosure, the standard format of the mesh model configuration file includes a shape file, a material file, and a mapping file. The mapping file may include the corresponding relationship between the shape and the material, such as the material of a certain patch. Based on the shape file, the material file, and the mapping file, a three-dimensional mesh model can be rendered.

[0066] In the embodiments of the present disclosure, the non-standard format of the patch data, normal data, and texture data can be converted into a standard format of the shape file in the data format conversion tool of the platform. The non-standard format of the material data can be converted into a standard format of the material file in the data format conversion tool of the platform. The mapping relationship between the material in the material file and the shape in the shape file can be used to generate a mapping file.

[0067] According to the embodiments of the present disclosure, the non-standard format of the patch data, normal data, texture data, and material data can be converted into a standard format of the mesh model configuration file, which is convenient for rendering the three-dimensional mesh model according to the standard format of the mesh model configuration file.

[0068] In one implementation, as Figure 3As shown, S204 renders the mesh model of the object according to the mesh model configuration file, including:

[0069] S408. Render according to the shape file to obtain an initial model;

[0070] S409. Obtain material information according to the material file;

[0071] S410. Render the material information into the initial model according to the mapping file according to the corresponding relationship to obtain the mesh model of the object.

[0072] In the embodiment of the present disclosure, by using the shape file in the mesh model configuration file, an initial three-dimensional mesh model can be rendered. The initial three-dimensional mesh model mainly includes the shape of three-dimensional geometric figures and does not include the material of three-dimensional geometric figures. Then, through the mapping file, the material corresponding to each patch of the three-dimensional geometric figure is retrieved in the material file. After obtaining the corresponding material, the material is rendered onto the patch. After the material rendering of all patches is completed, a three-dimensional mesh model with material can be obtained for user use.

[0073] According to the embodiment of the present disclosure, a final three-dimensional mesh model with material can be rendered.
