[0029] It should be noted that, Figure 1 The scene schematic diagram of the virtual scene model processing system shown is only an example, and the virtual scene model processing system and the scene described in the embodiment of the present application are used to more clearly illustrate the technical solutions of the embodiment of the present application, and do not constitute a limitation on the technical solutions provided by the embodiment of the present application. It is known to those skilled in the art that, as the virtual scene model processing system evolves and new business scenarios appear, the technical solutions provided by the embodiment of the present application are also applicable to similar technical problems.

[0030] The virtual scene model processing method provided in the embodiments of the present application can use model making application software, for example, 3D MAX (3D Studio MAX) can be used. 3D MAX is a PC system based three-dimensional animation rendering and making software, which can be used in animation making of computer games and special effect making of films and television programs, etc. A game maker can pre-set the size and shape of a model, and make a virtual scene model in 3D MAX based on the pre-set model size and shape.

Common DCC software includes Autodesk Maya, Autodesk 3ds Max, Cinema 4D, Blender, Houdini, etc.

[0031] The virtual scene model processing method, device, computer device and storage medium provided in the embodiments of the present application can be used in cooperation with a terminal such as a smart phone, a tablet computer, a notebook computer or a personal computer, etc. The virtual scene model processing method, device, computer device and storage medium are described in detail below. It should be noted that the description order of the following embodiments is not limited to the preferred order of the embodiments.

[0032] Please refer to Figure 2 , Figure 2 A flowchart of the virtual scene model processing method provided in the embodiments of the present application is shown in FIG. 1. The specific process can include the following steps 101 to 104.

[0033] 101. At least one target virtual scene model is obtained from a pre-set virtual scene space, wherein the target virtual scene model is composed of a plurality of polygon meshes.

[0034] In the embodiments of the present application, after the step of "obtaining at least one target virtual scene model from a pre-set virtual scene space", the following steps are further included:

[0035] The target virtual scene model is exported from the virtual scene space through a file export interface corresponding to a first file format, to obtain a model file in the first file format corresponding to the target virtual scene model.

[0036] Specifically, all virtual scene models in the preset virtual scene space can be exported through a file export interface (FBX API) corresponding to the first file format, that is, all virtual scene models are exported from the virtual scene space to obtain a plurality of model files in the first file format (that is, FBX files) corresponding to the virtual scene models.

[0037] The file export interface corresponding to the first file format can be an FBX API. The FBX API is an interface provided by Autodesk for modifying FBX properties. Specifically, the FBX API is a set of application programming interfaces (APIs) for processing FBX (Filmbox) file formats. Further, FBX is a file format for exchanging and storing 3D models, animations, and related data, developed and maintained by Autodesk. The FBX API allows developers to access and manipulate the contents of FBX files in application programs. By using the FBX API, developers can read, write, and modify various elements of virtual scene models in FBX files, such as objects, materials, textures, animations, and skeletons. In addition, custom tools and scripts can be created to automate the processing of FBX files, such as importing and exporting models, converting animations, and editing materials. The FBX API also provides access and parsing functions for the structure of FBX files, so that developers can understand and manipulate the hierarchical structure and data relationships of the files.

[0038] 102, based on a preset decimation parameter, the polygon mesh of the target virtual scene model is decimated to obtain a processed virtual scene model.

[0039] In the embodiments of the present application, the step of "based on a preset decimation parameter, the polygon mesh of the target virtual scene model is decimated to obtain a processed virtual scene model", the method can include:

[0040] The decimation function interface is called to decimate the polygon mesh of the target virtual scene model corresponding to the model file to obtain a processed virtual scene model and a model file in the second file format corresponding to the processed virtual scene model.

[0041] Specifically, the decimation function interface (python api provided by Simplygon) can be called to decimate the polygon mesh of the virtual scene model corresponding to the model file in the first file format (that is, the FBX file) corresponding to the plurality of virtual scene models to obtain a processed virtual scene model and a model file in the second file format corresponding to the processed virtual scene model. By using the python api provided by Simplygon, a local fbx file can be converted into two decimated physical resources as input resources.

[0042] In order to maintain the original shape of the virtual scene model to the maximum extent while keeping the original scene model unchanged, in the embodiments of the present application, the local fbx decimation rate can be adjusted to 80% and 50% by using Simplygon API. Simplygon API is the application programming interface (API) of Simplygon. Simplygon is a software tool for 3D content optimization, and Simplygon API allows developers to integrate and use the functions of Simplygon in their applications. Specifically, through Simplygon API, developers can automate polygon reduction, LOD (Level of Detail) generation, texture compression and optimization of 3D models. Code can also be written to call Simplygon API to process and optimize complex 3D models, thereby improving real-time rendering performance, reducing bandwidth requirements and increasing loading speed. Simplygon API provides various functions and options, allowing developers to customize according to their needs and application scenarios. Simplygon API can be integrated with various development environments and programming languages such as C++, C#, Python, etc., allowing developers to use Simplygon functions in different platforms and environments. By using Simplygon API, developers can easily integrate 3D content optimization functions into their applications to improve performance and optimize user experience.

[0043] In an embodiment, the step of "decimating the polygon mesh of the target virtual scene model based on the preset decimation parameters to obtain a processed virtual scene model" can include:

[0044] Obtaining shape constraint parameters and decimation ratio parameters;

[0045] Decimating the polygon mesh of the target virtual scene model based on the shape constraint parameters and the decimation ratio parameters to obtain a processed virtual scene model.

[0046] Further, the step of "decimating the polygon mesh of the target virtual scene model based on the shape constraint parameters and the decimation ratio parameters to obtain a processed virtual scene model" can include:

[0047] Constraining the model shape of the target virtual scene model based on the shape constraint parameters, and processing the number of meshes of the polygon mesh of the target virtual scene model based on the decimation ratio parameters to obtain a processed virtual scene model.

[0048] The surface reduction ratio parameter can be 80% or 50%. When the surface reduction ratio parameter is 80%, the generated surface reduction scene model can be used to make a physical resource for detecting the walking of a virtual character. When the surface reduction ratio parameter is 50%, the generated surface reduction scene model can be used to make a physical resource for detecting scene interaction. Specifically, when the surface reduction ratio parameter is 80%, the number of polygon meshes to be retained is 80% of the total number of original polygon meshes. When the surface reduction ratio parameter is 50%, the number of polygon meshes to be retained is 50% of the total number of original polygon meshes. It should be noted that the surface reduction ratio parameter can also be other numerical values, such as 20%, 30%, or 70%, and the like. The above is only an example and is not limited.

[0049] Specifically, the shape constraint parameter can include a deviation ratio, a first module parameter corresponding to a first function module (Geometry Approximation Settings), and a second module parameter corresponding to a second function module (Opmization Settings). The deviation ratio is used to switch the global clipping distance ratio on which the effect preview depends. Since a physical resource needs to be made, the deviation ratio should be as small as possible. Geometry Approximation Settings is used to select the shape of the object. Different geometric approximation levels can be set to achieve this. Generally, a higher approximation level can better preserve the shape of a virtual object, but it will also increase the number of polygons in the model. The Opmization Settings function can be in the optimization settings of Simplygon. Any shape optimization option can be selected, which will ensure that the shape and topology of the virtual object will not be modified, thereby preserving its original shape.

[0050] Optionally, the shape constraint parameter and the surface reduction ratio parameter are obtained by:

[0051] The first surface reduction ratio parameter corresponding to the first physical function, the second surface reduction ratio parameter corresponding to the second physical function, and the shape constraint parameter are obtained.

[0052] The polygon meshes of the target virtual scene model are subjected to surface reduction processing based on the shape constraint parameter and the first surface reduction ratio parameter, to obtain a first processed virtual scene model. The first processed virtual scene model is used to generate a target virtual scene model with a first target physical function.

[0053] Based on the shape constraint parameter and the second decimation ratio parameter, the polygon mesh of the target virtual scene model is subjected to decimation processing to obtain a second processed virtual scene model, wherein the second processed virtual scene model is used to generate a target virtual scene model with a second target physical function.

[0054] Optionally, two or more decimation ratio parameters can be obtained to generate multiple virtual scene models with different physical functions.

[0055] In the embodiments of the present application, the selected target virtual scene model in the preset virtual scene space can be exported through a file export interface (FBX API) corresponding to a first file format to obtain a model file (i.e., an FBX file) of the target virtual scene model in the first file format. Then, a first decimation ratio parameter 80% corresponding to a first physical function, a second decimation ratio parameter 50% corresponding to a second physical function, and a shape constraint parameter are obtained. The decimation scene model generated when the decimation ratio parameter is 80% can be used to make physical resources for detecting the walking of a virtual character, and the decimation scene model generated when the decimation ratio parameter is 50% can be used to make physical resources for detecting scene interaction. Next, based on the shape constraint parameter and the first decimation ratio parameter 80%, the polygon mesh of the target virtual scene model is subjected to decimation processing to obtain a first processed virtual scene model, which is used to make physical resources for detecting the walking of a virtual character; based on the shape constraint parameter and the second decimation ratio parameter 50%, the polygon mesh of the target virtual scene model is subjected to decimation processing to obtain a second processed virtual scene model, which is used to make physical resources for detecting scene interaction.

[0056] 103. Based on the preset physical attribute parameter and the processed virtual scene model, a target physical resource with a target physical function is generated.

[0057] In the embodiments of the present application, a corresponding physical resource can be generated according to a virtual scene model. The physical resource processing includes a target bounding box and also has physical attributes, physical materials, and physical interaction information. For example, some physical resources can interact with other virtual objects (such as bullets) in a virtual scene, and some physical resources can be used for a virtual character to walk in a virtual scene.

[0058] Specifically, in addition to the bounding box, the physical resource in the embodiment of the present application can also include collision properties, rigid body type, collision determination, and physical material settings, etc., wherein, the physical center point of the model and the coordinates of the bounding box relative to the model can be found to generate a target bounding box; the model can be set with collision properties for collision testing; the type of rigid body can also be set; angle offset, maximum angular velocity determination can also be performed, and a callback method after physical collision can also be set to determine whether the gravity effect is received.

[0059] In a specific embodiment, a target bounding box with a target physical function can be generated based on preset bounding box parameters and the model shape of the processed virtual scene model; then, the target bounding box is mounted to the target virtual scene model to obtain a target virtual scene model with the target physical function.

[0060] Specifically, the method further includes:

[0061] The model file in the second file format corresponding to the processed virtual scene model is imported into the game engine where the target virtual scene model is located, and the game engine is called to perform physical resource generation processing on the model file in the second file format to obtain a target bounding box with a target physical function corresponding to the processed virtual scene model, and a physical resource file corresponding to the target bounding box.

[0062] In the embodiment of the present application, the step of "generating a target bounding box with a target physical function based on preset bounding box parameters and the model shape of the processed virtual scene model" can include:

[0063] Obtaining preset bounding box parameters, wherein the preset bounding box parameters include bounding box size parameters and bounding box shape parameters;

[0064] Determining the center point position of the model shape based on the model shape of the processed virtual scene model;

[0065] Generating a target bounding box with a target physical function based on the center point position, the bounding box size parameters and the bounding box shape parameters.

[0066] For example, please refer to Figure 3acquire preset bounding box parameters, wherein the preset bounding box parameters comprise a bounding box size parameter and a bounding box shape parameter, the bounding box size parameter can be determined based on the model size of the processed virtual scene model to ensure that the target bounding box can completely wrap the processed virtual scene model into the target bounding box, and the bounding box shape parameter can be a spherical parameter, and meanwhile, the model shape based on the processed virtual scene model is acquired, the center point position of the model center point of the model shape based on the processed virtual scene model is determined, and then the target bounding box with the target physical function is generated based on the center point position, the bounding box size parameter and the bounding box shape parameter.

[0067] In order to generate a physical resource that fits the target virtual scene model, before the step of "acquiring preset bounding box parameters", the method can comprise:

[0068] acquiring the model shape and the model size of the processed virtual scene model;

[0069] determining the bounding box shape parameter based on the model shape;

[0070] determining the bounding box size parameter based on the model size.

[0071] For example, please refer to Figure 4 acquiring the model shape and the model size of the processed virtual scene model, determining the bounding box shape parameter based on the model shape, determining the bounding box size parameter based on the model size, determining the center point position of the model center point of the model shape based on the model shape of the processed virtual scene model, and then generating the target bounding box with the target physical function based on the center point position, the bounding box size parameter and the bounding box shape parameter.

[0072] It should be noted that the model center point of the model shape can be a position determined by the computer device itself, and the model center point of the model shape can also be a position set by the developer in the model shape. The shape of the bounding box can be a regular shape, such as a rectangle, a sphere, or other polygons, or can be the same shape as the model shape of the virtual scene model, or can be a shape defined by the developer. Further, the shape of the bounding box can also be determined according to the physical function that the virtual scene model needs to have, for example, when the virtual scene model is a virtual house model, the bounding box of the virtual house model can be consistent with the model shape of the virtual house model; when the virtual scene model is a virtual bonfire, in order to simulate the distance between a person and the bonfire in a real situation, a circular spherical bounding box can be generated based on the center point of the virtual bonfire, so that there is a certain distance between the virtual character and the virtual bonfire, thereby enabling the virtual character and the virtual bonfire in the game scene to simulate the distance between a person and the bonfire in a real situation; when the virtual scene model is a virtual vehicle, such as a virtual car, an elliptical spherical bounding box that just wraps the virtual car can be drawn, thereby enabling the virtual character and the virtual car to simulate the distance between a person and the car in a real situation.

[0073] In order to enable the developer to personalize the bounding box, before the step of "obtaining preset bounding box parameters", the method can comprise:

[0074] displaying a graphical user interface, the graphical user interface displaying a parameter setting page, wherein the parameter setting page includes at least one parameter input interface;

[0075] in response to a submission operation of parameter information input to the parameter input interface, obtaining the input parameter information as preset bounding box parameters.

[0076] For example, the computer device can display a graphical user interface, the graphical user interface displaying a parameter setting page, wherein the parameter setting page includes at least one parameter input interface, the at least one parameter input interface including a shape parameter input interface, a size parameter input interface, and a bounding box attribute parameter input interface, the developer can input the bounding box shape parameter through the shape parameter input interface, can input the bounding box size parameter through the size parameter input interface, and can input the bounding box attribute parameter configured for the bounding box through the bounding box attribute parameter input interface. The computer device can obtain the input bounding box shape parameter, bounding box size parameter, and bounding box attribute parameter as preset bounding box parameters in response to a submission operation of parameter information input to the shape parameter input interface, the size parameter input interface, and the bounding box attribute parameter input interface.

[0077] 104, mounting the target physical resource to the target virtual scene model to obtain a target virtual scene model with the target physical function.

[0078] In the embodiments of the present application, the link of the target physical resource can be mounted to the target virtual scene model, so that the target virtual scene model has the physical characteristics corresponding to the target physical resource. Specifically, the link of the target physical resource can be connected under the physical attribute information corresponding to the attribute information of the target virtual scene model, so that the target virtual scene model has the physical characteristics corresponding to the target physical resource.

[0079] In the embodiments of the present application, the method further comprises:

[0080] obtaining a target file path of the physical resource file;

[0081] associating the target file path with a model description file of the target virtual scene model to mount the target bounding box to the target virtual scene model to obtain a target virtual scene model with the target physical function.

[0082] Specifically, the present application can select a virtual scene model in a virtual scene (Messiah scene) in a game engine, and obtain a file in fbx format of a mesh model corresponding to the virtual scene (under mesh.fbx). Then, a Simplygon API is called to perform mesh reduction processing on the virtual scene model to obtain a model file of the reduced virtual scene model (reduced.fbx). Next, the model file (reduced.fbx) is imported into max, and then the model file (reduced.fbx) is imported into the game engine through max, so as to obtain the data of the reduced scene model in max. Further, the model file (reduced.fbx) is batch written, specifically, the model file (reduced.fbx) is batch converted into a binary engine physical resource (converted by the function of the game engine itself), and finally a physical description file is generated according to the above physical resource to obtain a virtual scene model with physical function.

[0083] In order to further illustrate the processing method of the virtual scene model provided in the embodiments of the present application, the application of the processing method of the virtual scene model in a specific implementation scene will be described as an example, and the specific scene is as follows:

[0084] (1) Batch export of all virtual scene models in the virtual space using FBX is possible. Specifically, developers can use the FBX API to export the resources of a whole set of static virtual scene models in the virtual space as FBX files back to the local space, and then use the FBX API to batch convert and name the imported FBX files to conform to the Simplygon file format. For example, all virtual scene models in a preset virtual scene space can be exported through the file export interface (FBX API) corresponding to the first file format, that is, all virtual scene models can be exported from the virtual scene space to obtain multiple model files (i.e., FBX files) in the first file format corresponding to the virtual scene models.

[0085] Developers can utilize the FBX interface provided by Autodesk to import FBX files of static virtual scene models from the virtual space to their local machine. Then, they can use the FBX API to batch modify the node names of the FBX files and encapsulate this into a user interface for easy batch operations by artists. This requires first establishing a connection between the game engine and the FBX API, and then exporting the resources of the static virtual scene models referenced by the scene in batches as a queue. The specific implementation code is shown below:

[0086] do query

[0087] fbx_files=os.listdir_("D:\TEST"+" / / "+"high_export"+" / / "+"fbx")

[0088] for fbx in fbx_files:

[0089] gWatting = True

[0090] fbx_api.query_fbx_(fbx_file+" / / "+fbx,repo path,package_path)

[0091] fbx_ref.path=fbx_file+" / / "+fbx

[0092] while gWatting:

[0093] time.sleep_(0.01)

[0094] / / Load FBX file

[0095] FbxImporter*pImporter=FbxImporter::Create(pManager,"");

[0096] if (!pImporter->Initialize("test.fbx", -1, pManager->GetIOSettings()))

[0097] {

[0098] cerr << "Failed to load FBX file." << endl;

[0099] exit(0);

[0100] }

[0101] pImporter->Import(pScene);

[0102] pImporter->Destroy();

[0103] / / Modify Mesh node name
