Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0050] Embodiment 1

[0051] For ease of understanding of this application, the following combines Figure 1 the content described in the flowchart of a model rendering method provided in Embodiment 1 of the present invention shown in

[0052] Refer to Figure 1 shown in Figure 1 the flowchart of a model rendering method provided in Embodiment 1 of the present invention is shown. The method includes steps S101 to S104:

[0053] S101: Split each face of the target cells in the CAE model into triangular patches, where the target cells include all two-dimensional cells and all three-dimensional cells in the CAE model.

[0054] Specifically, CAE (Computer Aided Engineering) is an approximate numerical analysis method for using a computer to assist in solving problems such as the analysis and calculation of the mechanical properties of complex engineering and product structural strength, stiffness, buckling stability, dynamic response, heat conduction, three-dimensional multi-body contact, elastoplasticity, etc., as well as the optimization design of structural performance.

[0055] When splitting the faces of the two-dimensional cells and three-dimensional cells in the CAE model, the model file of the CAE model originally carries the vertex coordinates of each vertex of the two-dimensional cells and three-dimensional cells. The two-dimensional cells and three-dimensional cell faces are split according to the point set composed of the vertex coordinates of each vertex to obtain triangular patches.

[0056] Refer to Figure 2 shown in Figure 2The figure shows a schematic diagram of a method for splitting a rectangular face of a two-dimensional unit provided in the first embodiment of the present invention. Taking the two-dimensional unit A as an example, the two-dimensional unit A is a rectangular face, and the four vertices of this rectangular face are A1, A2, A3, and A4 respectively, with coordinates A1(a1, b1, c1), A2(a2, b2, c2), A3(a3, b3, c3), and A4(a4, b4, c4). Among them, A1 and A2 are connected by the rectangular side A1A2, A2 and A3 are connected by the rectangular side A2A3, A3 and A4 are connected by the rectangular side A3A4, and A4 and A1 are connected by the rectangular side A4A1. When splitting the rectangular face of the two-dimensional unit A, any two adjacent (having a common endpoint) rectangular sides (A1A2 and A2A3 or A2A3 and A3A4 or A4A1 and A1A4 or A4A1 and A1A2) are arbitrarily selected, and a triangular face is determined with the three vertices of these two adjacent rectangular sides as the three vertices of the triangle. Then, the remaining part in the rectangular face is used as another triangular face.

[0057] See Figure 3 as shown in Figure 3 The figure shows a schematic diagram of a method for splitting a rectangular face of a three-dimensional unit provided in the first embodiment of the present invention. Taking the three-dimensional unit D as an example, the three-dimensional unit D is a cuboid. The 8 vertices of this three-dimensional unit D are respectively marked as D1, D2, D3, D4, D5, D6, D7, and D8. The four vertices of the first rectangular face are D1, D2, D3, and D4 respectively, with coordinates D1(d1, e1, f1), D2(d2, e2, f2), D3(d3, e3, f3), and D4(d4, e4, f4). Among them, D1 and D2 are connected by the rectangular side D1D2, D2 and D3 are connected by the rectangular side D2D3, D3 and D4 are connected by the rectangular side D3D4, and D4 and D1 are connected by the rectangular side D4D1. When splitting the first rectangular face of the three-dimensional unit D, any two adjacent (having a common endpoint) rectangular sides are arbitrarily selected, and a triangular face is determined with the three vertices of these two adjacent rectangular sides as the three vertices of the triangle. Then, the remaining part in the rectangular face is used as another triangular face; thus, 12 triangular faces can be obtained by splitting the three-dimensional unit D.

[0058] S102: Construct the surface geometry of the target unit with all the triangular faces according to the vertex coordinates of the target unit.

[0059] Specifically, after obtaining all the triangular faces in the target unit in step S101, construct the surface geometry of the target unit according to the vertex coordinates in the target unit (this data is carried in the model file of the original CAE model).

[0060] S103: Store the surface geometric body, the first-line geometric body, and the second-line geometric body as the content of the candidate model file of the candidate three-dimensional model, where the first-line geometric body is constructed according to the edge line of the target unit, the edge line is generated according to the vertex coordinates of the target unit using a preset edge line connection rule, and the second-line geometric body is constructed according to the one-dimensional units in the CAE model.

[0061] Specifically, when determining the first-line geometric body, construct the edge line of the target unit according to the vertex coordinates of the target unit. For example, for a two-dimensional rectangular unit, take its four rectangular sides as the edge lines, and then construct the first-line geometric body of the target unit with all the edge lines. The target unit is the set of all two-dimensional units and three-dimensional units. When determining the second-line geometric body, directly construct the second-line geometric body according to the vertex coordinates of all one-dimensional units.

[0062] Store the first-line geometric body, the second-line geometric body, and the surface geometric body obtained in step S102 as the content of the candidate model file of the candidate three-dimensional model.

[0063] S104: Render the content of the candidate model file using the WebGL engine to display the candidate three-dimensional model on the Web side.

[0064] Specifically, when the user needs to render the candidate three-dimensional model file, the front-end three-dimensional visualization component can be enabled by clicking the render button in the Web page. The three-dimensional visualization component can use the WebGL (Web Graphics Library, a 3D drawing protocol) engine to render the candidate three-dimensional model to render the candidate three-dimensional model on the Web (World Wide Web) side.

[0065] In a feasible implementation, as shown in Figure 4 shown, Figure 4 shows the flowchart of a unit determination method provided in Embodiment 1 of the present invention. Before splitting each face of the target unit in the CAE model into triangular patches, the method further includes steps S401 to S403:

[0066] S401: Determine the units with a line structure in the CAE model as the one-dimensional units.

[0067] Specifically, determine the units with a line structure such as rod units and beam units in the CAE model as one-dimensional units.

[0068] S402: Determine the units with a surface structure in the CAE model as the two-dimensional units.

[0069] Specifically, units with surface structures such as shell units and shear units in the CAE model are determined as two-dimensional units.

[0070] S403: Determine units with a volume structure in the CAE model as the three-dimensional units.

[0071] Specifically, units with a volume structure such as tetrahedral units, pentahedral units, and hexahedral units in the CAE model are determined as three-dimensional units.

[0072] In a feasible implementation, after storing the surface geometric body, the first-line geometric body, and the second-line geometric body as the content of the candidate model file of the candidate three-dimensional model, the method further includes:

[0073] Upload the content of the candidate model file to the cloud file library of the cloud server so that all users who can access the cloud server can obtain the content of the candidate model file from the cloud file library.

[0074] Specifically, taking the candidate model file of civil aircraft engineering as an example, after uploading the content of the candidate model file to the cloud file library of the cloud server, the content of the candidate model file of civil aircraft engineering in the cloud file library is accessed and stored through the object storage service, and combined with the content delivery network technology, so that all users who can access the cloud server can obtain or download the content of the candidate model file from the cloud file library.

[0075] In a feasible implementation, refer to Figure 5 as shown, Figure 5 The figure shows a flowchart of a method for rendering the content of a target model file provided in the first embodiment of the present invention. Among them, after using the WebGL engine to render the content of the candidate model file to display the candidate three-dimensional model on the Web side, the method further includes steps S501 to S502:

[0076] S501: Add the target rendering data to the content of the candidate model file to obtain the content of the target model file of the target three-dimensional model, where the target rendering data is the rendering data for modifying the rendering effect of the candidate three-dimensional model to the rendering effect of the target three-dimensional model.

[0077] Specifically, when it is necessary to modify the rendering effect of the candidate 3D model obtained through step S104, it is first necessary to determine the data that needs to be modified in the candidate model file content when modifying the rendering effect of the candidate 3D model. Taking the content of the candidate model file for civil aircraft engineering as an example, the computing engine of the server calculates the target rendering data of the unit that needs to modify the model rendering attributes (such as color, etc.). The target rendering data is the rendering data for modifying the rendering effect of the candidate 3D model to the rendering effect of the target 3D model. Then, the target rendering data is added to or modified in the original candidate model file content to obtain the target model file content that can achieve the rendering effect of the target 3D model.

[0078] S502: Use the WebGL engine to render the target model file content to display the target 3D model on the Web side.

[0079] Specifically, when the user needs to render the target 3D model file, the front-end 3D visualization component can be enabled by clicking the rendering button on the Web page. The 3D visualization component can use the WebGL engine to render the target 3D model to render the target 3D model on the Web side.
