Description

Technical Field

[0001] This application relates to the field of games, specifically to a scene model processing method, apparatus, electronic device, and storage medium, wherein the storage medium includes a computer-readable storage medium. Background Technology

[0002] As versions are continuously updated and iterated, the production specifications for scene assets vary at different stages, and the asset data gradually becomes enormous. Scene models are an important resource in scene assets, generating display images after rendering, such as 3D scene images like game screens. How to maintain and manage scene models is an important problem that needs to be solved.

[0003] Currently, a method has been designed to improve the development efficiency of scene resources and reduce the generation of new resources by reusing scene models. For example, scene models from PC games can be reused in mobile games, or scene models from other games can be reused in the development of scene resources for the current game.

[0004] However, since scene models are usually developed independently, some hidden surfaces inevitably exist when scene models are reused and combined. For example, these hidden surfaces may be hidden or occluded in other scene models when the scene model is displayed. Due to the large number of scene models, the number of such hidden surfaces is also large, which wastes resources and affects performance when rendering scene models. Manually screening and processing these hidden surfaces is inefficient and costly. Summary of the Invention

[0005] This application provides a scene model processing method, apparatus, electronic device, and storage medium, which can improve the screening efficiency of invalid patches in the scene model and facilitate the optimization of the scene model.

[0010] The target facet in the scene mesh model is deleted to obtain the updated scene mesh model.

[0011] Secondly, embodiments of this application also provide a scene model processing apparatus, including:

[0015] The deletion module is used to delete the target facet in the scene mesh model to obtain an updated scene mesh model.

[0016] Thirdly, embodiments of this application also provide an electronic device, including a memory storing multiple instructions; the processor loads instructions from the memory to execute any of the scene model processing methods provided in embodiments of this application.

[0017] Fourthly, embodiments of this application also provide a computer-readable storage medium storing a plurality of instructions adapted for loading by a processor to execute any of the scene model processing methods provided in embodiments of this application.

[0018] In this embodiment, by determining the target virtual object mesh model for filtering faces and the geometric space occupied by the target virtual object mesh model, once faces of other scene object mesh models contained in this geometric space are identified, the filtering of target faces to be deleted is achieved, improving the efficiency of filtering invalid faces in the scene mesh model. By deleting the target face from the scene mesh model, the scene mesh model is optimized, reducing the number of faces required to be rendered during scene mesh model rendering. It also avoids rendering invalid faces, preventing resource waste and improving performance. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. At the same time, in the description of the embodiments of this application, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] This application provides a scene model processing method, apparatus, electronic device, and storage medium.

[0029] Specifically, this embodiment will be described from the perspective of a scene model processing device, which can be integrated into an electronic device. That is, the scene model processing method of this application embodiment can be executed by an electronic device, which can be a terminal device. The terminal device can be a tablet computer, a laptop computer, a touch screen, or a personal computer (PC), etc.

[0030] In some embodiments, the scene model processing device can also be integrated into the terminal and server cluster to realize cloud gaming; wherein, the terminal can transmit the received operation to the server, and the server updates the game interface based on the received operation, and then receives the updated interface information transmitted by the server to update the game interface.

[0031] For example, the scene model processing method provided in this application embodiment can be applied to a scene model processing system. This system can include a terminal and a server. The terminal can be a device that includes both receiving and transmitting hardware, i.e., a device with receiving and transmitting hardware capable of performing bidirectional communication over a bidirectional communication link. Specifically, the terminal can be a terminal device used to run a game application, such as a mobile phone, tablet computer, or laptop computer. The terminal and server can communicate bidirectionally via a network. The server can store data required for game operation, such as scene model resources. The terminal obtains game data required for game operation from the server via the network to display the game interface of the target game and interact with the player, such as the terminal obtaining a game scene model and displaying the game scene interface on the terminal interface. The server can be a standalone server or a server network or server cluster, including but not limited to computers, network hosts, single network servers, multiple network server sets, or cloud servers composed of multiple servers. The cloud server consists of a large number of computers or network servers based on cloud computing.

[0032] The following detailed description is provided in conjunction with the accompanying drawings. This embodiment uses a terminal device equipped with a scene mesh model as the execution subject, and the scene model processing method provided in this embodiment is executed by the processor of the terminal device. For simplicity, this execution subject will be omitted in the following text. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0033] Please refer to Figure 1 The specific process of this scene model processing method can be summarized in steps 101 to 104, where:

[0034] 101. Obtain the scene mesh model, which is obtained by combining at least two scene object mesh models.

[0035] It should be noted that the scene mesh model is a model with size, shape, and representation of 3D objects. This scene mesh model represents the overall outline of the entire scene. Correspondingly, the scene object mesh model is a component of the scene mesh model. Typically, the scene object mesh model is a small, independently developed mesh model. For example, please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is a schematic diagram of the interface of the scene mesh model provided in the embodiment of this application, which shows the scene mesh model representing the overall outline of the scene and multiple scene object mesh models that combine the scene mesh model.

[0036] It is understood that, in the embodiments of this application, the scene mesh model can be obtained from the server. For example, a scene mesh model acquisition instruction can be sent to the server, and the scene mesh model can be obtained by receiving the server's feedback on the instruction.

[0037] Accordingly, in the embodiments of this application, the scene mesh model can also be obtained from scene object mesh models from other devices and combined to obtain the scene mesh model. For example, the scene object mesh model sent by other terminal devices can be received, and then the scene object mesh model can be imported into the current terminal. By adjusting the position, size, etc., the scene mesh model can be combined to obtain the scene mesh model.

[0038] Because scene mesh models involve large amounts of data, they are typically derived from a combination of multiple scene object mesh models. This means that multiple scene object mesh models can be developed independently to accelerate development. For example, multiple developers can be assigned to develop scene object mesh models separately, and then these individual scene object mesh models can be combined to generate the overall scene mesh model.

[0039] Similarly, in order to improve the development efficiency of scene mesh models, related technologies also speed up the development process by reusing existing mesh models. For example, mesh models from other games can be copied into the current scene model and combined to obtain the scene mesh model.

[0040] However, since scene object mesh models are either independently developed or reused from other games, overlap and occlusion inevitably occur during the combination of scene object mesh models. Consequently, some faces in the scene mesh model will not be displayed in the scene interface. In order to filter out these invalid faces, in this embodiment of the application, the combined scene mesh model is obtained to identify and filter out invalid faces, thereby facilitating the optimization of the scene mesh model by deleting these invalid faces.

[0041] 102. Determine the target virtual object mesh model for filtering patches from the scene object mesh model, and determine the geometric space occupied by the target virtual object mesh model in the scene mesh model according to the outline of the target virtual object mesh model.

[0042] It is understandable that occlusion or hiding may exist between two scene object mesh models in a scene mesh model. Therefore, in this embodiment, any scene object mesh model can be selected as the target virtual object mesh model. Then, the target patch to be deleted is determined by comparing other scene object mesh models with the target virtual object mesh model. For example, in this embodiment, each scene object mesh model can be traversed, and the traversed scene object mesh model can be used as the target virtual object mesh model. Correspondingly, the untraversed scene object mesh models are compared with the target virtual object mesh model.

[0043] It is understood that in the embodiments of this application, geometric space refers to the space occupied by the outline of the target virtual object mesh model. Occlusion and hiding usually occur when a face is in the space occupied by other scene object mesh models. Therefore, in the embodiments of this application, the geometric space of the target virtual object mesh model can be determined, and the occluded or hidden faces in other scene object mesh models in that geometric space can be filtered out.

[0044] 103. For any scene object mesh model other than the target virtual object mesh model in the scene mesh model, determine the target patch contained in the geometric space in the any scene object mesh model.

[0045] Accordingly, since there may be occlusions and hidden faces between the two scene object mesh models, in this embodiment of the application, after selecting the target virtual object mesh model, it is necessary to compare each of the other scene object mesh models in the scene mesh model, except for the target virtual object mesh model, with the geometric space corresponding to the target scene virtual object mesh model to determine whether there are faces contained in the geometric space.

[0046] Accordingly, in this embodiment, the target patch is a patch contained in the geometric space of the target virtual object mesh model by other scene object mesh models. Since the patch is located in the geometric space of other mesh models, it is not displayed in the scene interface when the interface is displayed. Therefore, the patch is an invalid patch when the scene mesh model constructs the scene screen.

[0047] 104. Delete the target facet in the scene mesh model to obtain the updated scene mesh model.

[0048] It is understandable that, since the target facet is the facet that needs to be deleted to optimize the scene mesh model, once the target facet to be deleted is determined, it can be deleted from the scene mesh model to obtain the optimized and updated scene mesh model.

[0049] It is understood that, in this embodiment of the application, by determining the target virtual object mesh model for filtering faces and determining the geometric space occupied by the target virtual object mesh model, once faces of other scene object mesh models contained in this geometric space are determined, the filtering of target faces to be deleted is achieved, thereby improving the efficiency of filtering invalid faces in the scene mesh model. By deleting the target face from the scene mesh model, the scene mesh model is optimized, reducing the number of faces required to be rendered during scene mesh model rendering, while also avoiding rendering of invalid faces, avoiding resource waste, and improving performance.

[0050] Optionally, a face has multiple vertices. Therefore, whether a face is in geometric space can be determined by whether the vertices are in geometric space. Thus, in this embodiment, a face whose vertices are all in geometric space can be used as a target face. That is, optionally, in some embodiments of this application, the step "determining that any scene object mesh model contains a target face in the geometric space" includes:

[0051] Based on the geometric space, candidate faces of vertices in the mesh model of any scene object are determined, and candidate faces of the corresponding particles of the vertices that are also in the geometric space are taken as target faces.

[0052] To ensure the accuracy of determining whether a face is in geometric space, this embodiment further improves the accuracy of the determination by checking whether the mass corresponding to the vertex is in geometric space. That is, a face where both the vertex and its corresponding mass are in geometric space is considered the target face.

[0053] In this embodiment, the methods for determining whether a vertex and a mass are in geometric space are the same. Therefore, in this embodiment, the method for determining whether a vertex is in geometric space is used as an example for explanation, while the method for determining whether a mass is in geometric space can be understood by referring to the method for determining whether a vertex is in geometric space.

[0054] Optionally, in this embodiment of the application, the scene object mesh model may include a terrain resource mesh model and a ground resource mesh model above the terrain. The terrain resource mesh model corresponds to the terrain in the scene interface, such as the mesh model corresponding to mountains, plains, etc. The ground resource mesh model is a mesh model located above the terrain resource mesh model, such as the mesh model corresponding to plants, buildings, etc.

[0055] For the terrain resource grid model, the main focus is on identifying whether there are any patches located below the terrain resource grid model. Therefore, a geometric space can be constructed in the space below the terrain resource grid model to determine whether there are any patches located below the terrain resource grid model. For the above-ground resource grid model, the main focus is on determining whether there are any overlapping patches. Therefore, in this embodiment, corresponding geometric spaces can be constructed for the terrain resource grid model and the above-ground resource grid model respectively, and then the target patches to be deleted can be identified.

[0056] For example, taking the target virtual object mesh model as a ground resource mesh model, correspondingly, any other scene object mesh model can be a ground resource mesh model or a terrain resource mesh model. Specifically, the determination of whether something is included in the geometric space of the ground resource mesh model can be made by the angle between the line connecting the vertices of the face in the two mesh models and the normal vector corresponding to the face. That is, optionally, in some embodiments of this application, the step "the target virtual object mesh model is a ground resource mesh model, and the step of determining the candidate face in the geometric space where the vertices of any scene object mesh model are located" includes:

[0057] The surface of the above-ground resource grid model is used as the reference surface, and the surface of any scene object grid model is used as the surface to be processed.

[0058] For each facet to be processed, calculate the angle between the line connecting the vertex of the facet to be processed and the vertex of each reference facet, and the normal vector of the corresponding reference facet.

[0059] If the included angles corresponding to the reference facets are all within the preset angle range, then the reference facets are used as facets to be counted.

[0060] The number of unprocessed face pieces corresponding to each unprocessed face piece is counted. If the number exceeds a preset threshold, the unprocessed face piece is considered a candidate face piece.

[0061] It is understandable that if the angle between the line connecting the vertices of the face to be processed and the normal vector of the reference face is within a preset angle range, then the vertex is considered to be in the geometric space. If all the vertices of the face are in the geometric space, then the face is considered to be a candidate face.

[0062] Optionally, in this embodiment, the preset angle range is set to 0-90 degrees. Correspondingly, the preset angle range can be narrowed or increased according to actual needs to improve the accuracy of candidate patch recognition.

[0063] Accordingly, in this embodiment of the application, the accuracy of candidate patch recognition can be improved by configuring a preset number threshold.

[0064] Optionally, in this embodiment of the application, for the above-ground resource grid model, the geometric space of the above-ground resource grid model can be defined by the model geometry modifier. For example, the above-ground resource grid model can be defined as a geometric space using a model geometry modifier in 3ds Max, where the geometric space can be a spherical space, a grid space, etc.

[0065] Accordingly, the following explanation uses the terrain resource grid model as the target virtual object grid model as an example. Similarly, any scene object grid model other than the target virtual object grid model in the scene grid model can be a ground resource grid model. Specifically, since the facets below the terrain resource grid model after the grid models are combined are not visible in the scene interface (i.e., facets occluded by the terrain resource grid model), a geometric space can be constructed in the space below the terrain resource grid model. The facets located in this geometric space can then be used as target facets. Optionally, in some embodiments of this application, the step "determining the geometric space occupied by the target virtual object grid model in the scene grid model based on the outline of the target virtual object grid model" includes:

[0066] Using the surface containing the outline of the terrain resource grid model as the top surface, a closed space is generated at the bottom of the terrain resource grid model;

[0067] The enclosed space is taken as the geometric space.

[0068] In this embodiment, since the facets located in the geometric space of the target virtual object mesh model are taken as facets to be deleted, and in fact the facets below the terrain resource mesh model are taken as facets to be deleted, a geometric space can be constructed below the terrain resource mesh model for the terrain resource mesh model, and then the facets located below the terrain resource mesh model can be deleted through the geometric space.

[0069] It is understandable that using the terrain resource mesh model as the top surface of the enclosed space ensures that the geometric space can encompass all faces located below the terrain resource mesh model, ensuring that all invalid faces are deleted during rendering. Accordingly, in this embodiment, the depth of the geometric space relative to the top surface of the terrain resource mesh model should be sufficiently deep to ensure a complete and comprehensive wrapping of faces in the ground resource mesh model that extend below the terrain resource mesh model.

[0070] Optionally, when constructing a closed space using the surface containing the outline of the terrain resource grid model as the top surface, it can be obtained by translating the edge of the terrain resource grid model downwards. For example, multiple vertices on the edge of the terrain resource grid model can be translated downwards to form the side surface of the geometric space, thereby generating the bottom surface relative to the side surface, and then enclosing the closed space. That is, optionally, in some embodiments of this application, the step "using the surface containing the outline of the terrain resource grid model as the top surface, generating a closed space at the bottom of the terrain resource grid model" includes:

[0071] Control at least two vertices on the edge of the terrain resource grid model to translate downwards, generating the side surface of the closed space corresponding to the terrain resource grid model;

[0072] The vertices on the bottom edge of the side surface are aggregated to generate the bottom surface of the closed space corresponding to the terrain resource grid model;

[0073] The top surface is the surface containing the outline of the terrain resource grid model, and a closed space is generated by enclosing the top surface, the side surface, and the bottom surface.

[0074] For example, please see Figure 3 As shown, Figure 3 This is a graphical schematic diagram of a closed model provided in an embodiment of this application. The closed model is obtained by enclosing the top surface, side surface and bottom surface, and the space contained in the closed model is the closed space.

[0075] Optionally, in this embodiment, the length of the side surface is flexibly selected based on the depth of the above-ground resource grid model, thereby obtaining a closed model or closed space that meets the depth requirements.

[0076] Optionally, in this embodiment, the aggregation of vertices on the bottom edge of the side surface can be a horizontal aggregation based on a horizontal plane, or a diagonal aggregation by selecting the midpoint downwards.

[0077] Optionally, in this embodiment, Boolean operations can be used to delete target patches in geometric space. Specifically, in this embodiment, Boolean operations are used to delete target patches when the target virtual object mesh model is a terrain resource mesh model. That is, the step "deleting the target patches in the scene mesh model to obtain an updated scene mesh model" includes:

[0078] Perform a Boolean subtraction operation on the geometric space and the mesh model of any scene object to delete both the geometric space and the target patch from the scene mesh model, thereby obtaining a local scene mesh model. The local scene mesh model includes the newly generated bottom surface of the mesh model of any scene object after the Boolean subtraction operation.

[0079] The newly formed bottom surface is deleted from the local scene mesh model to obtain the transition scene mesh model;

[0080] The terrain resource grid model is recombined into the transition scene grid model to obtain the updated scene grid model.

[0081] It is understood that, in the embodiments of this application, the Boolean subtraction operation between the geometric space and the scene object mesh model is actually a Boolean subtraction operation between the closed model corresponding to the geometric space and the scene object mesh model. This Boolean subtraction operation is used to delete both the closed model corresponding to the geometric space and the scene object mesh model.

[0082] Understandably, Boolean subtraction operations are used to quickly delete patches below the terrain resource grid model.

[0083] Accordingly, based on the characteristics of Boolean subtraction, in this embodiment, the newly created bottom face of the scene object mesh model after the Boolean subtraction operation is also deleted. Consequently, the result is a mesh model that only contains the terrain resource mesh model and the mesh model above the terrain resource mesh model (including the complete scene object mesh model and the scene object mesh model after subtraction).

[0084] Accordingly, since the terrain resource grid model is the top surface of a closed model, in order to obtain a new scene grid model that includes the terrain resource grid model, the terrain resource grid model is recombined into the transition scene grid model to obtain the updated scene grid model.

[0085] Optionally, in this embodiment, the newly formed bottom surface can be removed from the local scene mesh model based on its material to obtain a transitional scene mesh model. For example, when performing a Boolean subtraction operation, the material of the newly formed bottom surface can be set to be different from the material of the corresponding scene object mesh model, and then the newly formed bottom surface can be removed from the local scene mesh model based on the difference in material.

[0086] It is understood that, in this embodiment of the application, by determining the target virtual object mesh model for filtering faces and determining the geometric space occupied by the target virtual object mesh model, once faces of other scene object mesh models contained in this geometric space are determined, the filtering of target faces to be deleted is achieved, thus improving the efficiency of filtering invalid faces in the scene mesh model. By deleting the target face in the scene mesh model, the scene mesh model is optimized, reducing the number of faces required to be rendered during scene mesh model rendering, while also avoiding rendering of invalid faces, avoiding resource waste, and improving performance. By deleting faces below the terrain resource mesh model, by constructing a geometric space below the terrain resource mesh model, and using this geometric space through Boolean subtraction operations, the invalid faces below the terrain resource mesh model are quickly deleted.

[0087] Accordingly, in this embodiment, the method for deleting invalid faces in the combined scene mesh model can be integrated into a corresponding application. By providing a visual interface, invalid faces can be deleted from the combined scene mesh model through button selection. For example, please refer to... Figure 4 , Figure 4 This is a schematic diagram of the operation interface for the scene model processing method provided in this application embodiment. The schematic diagram shows a selection control A and a deletion control B, where the selection and deletion controls are respectively for two types of face reduction processing. Specifically:

[0088] For the first scenario, namely deleting faces below the terrain resource grid model, select control A1 as "Select terrain first, then select model," meaning first select the terrain resource grid model, then select the above-ground resource grid model. Delete control B1 includes "Delete faces below the terrain." Accordingly, the user selects the terrain resource grid model using control A1, then selects the above-ground resource grid model, and subsequently uses delete control B1 to delete the faces below the terrain resource grid model within the above-ground resource grid model. The specific process of this deletion operation includes:

[0089] 1) Topographic surface closure treatment;

[0090] Terrain resource mesh models are typically non-closed groups of faces containing height information. To reduce the number of faces, they need to be processed into a closed state first. Specifically, this involves selecting multiple vertices on the edge of the terrain mesh (in 3ds Max, you can select four vertices on the edge), shifting them downwards a certain distance, and finally merging these multiple vertices into a single vertex using a merge operation. Figure 3 As shown, the terrain thus becomes a closed state, resulting in a closed model;

[0091] 2) Use the procutter modifier to reduce the number of faces;

[0092] The procutter modifier is a modifier provided by 3ds Max for manipulating resource mesh models. It allows performing specific Boolean operations between two resource mesh models, primarily used for splitting or subdividing resource mesh models. The specific processing steps are as follows:

[0093] First, a 3ds Max procutter modifier is created for the terrain resource mesh model via a script. This means treating the terrain mesh model as a clipping space (corresponding to a closed model) and initializing it using the addMethod and stockOutsideCutter methods of the Move type.

[0094] The `addMethod` of type `Move` means that the clipping object (ground resource mesh model) selected by this clipping space will become part of the Boolean operation and will no longer be a separate operable geometry object.

[0095] The stockOutsideCutter method represents a Boolean subtraction operation between the clipping space and the clipping object, meaning that the two model meshes will perform a Boolean subtraction operation.

[0096] Secondly, the created procuttermodifier is used to perform the addStock operation, which operates on the ground resource mesh model. This means that the terrain mesh will be used as the clipping space, and the ground resource mesh model will be selected as the clipping object within this clipping space, while retaining the original material. This will result in a closed model (local scene mesh model) clipped along the terrain surface.

[0097] 3) Hollow out the bottom facets of the local scene mesh model generated in step 2);

[0098] In step 2), the material of the generated bottom facet is assigned to the material of the terrain resource mesh model. Therefore, the script filters out the facets with the terrain resource mesh model material from the local scene mesh model and deletes them, thereby achieving facet reduction optimization.

[0099] For the second type, namely the deletion of overlapping faces between aboveground resource grid models, select control A2 as "Please select models to be reduced and merged," indicating the selection of two models to be reduced and merged. Deletion control B2 includes "Delete overlapping faces between models." Accordingly, the user selects two models to be reduced and merged using control A2, and then executes the deletion operation on the faces between the aboveground resource grid models using deletion control B2. The specific process of this deletion operation includes:

[0100] 1) Traverse each aboveground resource grid model and calculate the hidden face patches in pairs through permutation and combination;

[0101] 2) The calculation of the interleaved hidden facets between every two ground resource grid models uses the vol.selectmodifier method:

[0102] `vol.select moditier` is a model geometry modifier in 3ds Max. It allows you to define a ground resource mesh model as a geometric space (spherical space, mesh space, etc.) and perform spatial calculations using the defined geometry space with another resource mesh model (including ground resource mesh models and terrain resource mesh models). It selects model mesh sub-objects represented by vertices or faces (model sub-objects can be simply understood as subsets of the model mesh). Specifically:

[0103] First, a `vol.select` modifier is created in a ground-based resource grid model, initialized to use patches to represent spatially computed model sub-objects (i.e., model subsets) and stacked for passing to the `vol.select` modifier of another resource grid model. Here, the selection of model sub-objects is completely independent of the geometry of the original ground-based resource grid model;

[0104] Secondly, the `vol.select` modifier is used to filter the mesh of one resource mesh model, and the other resource mesh model object is used as the computation object. This calculates the faces of one resource mesh model that are completely contained within the geometric space of the other resource mesh model, and caches these faces. The specific calculation principle is as follows (taking the determination of whether a vertex is completely contained within the geometric space of a certain resource mesh model as an example):

[0105] 1. For each triangular facet of the resource grid model (target virtual object grid model) that serves as the filtering space (geometric space), calculate its normal vector;

[0106] 2. For the vertex to be judged (the vertex of a triangle facet in any scene object mesh model), calculate the angle between the line connecting it to each vertex of each triangle facet (the triangle facet in the target virtual object mesh model) and the normal vector of each triangle facet (the triangle facet in the target virtual object mesh model);

[0107] 3. If the angle between the vertex and the normal vector of a certain triangle (a triangle facet in the target virtual object mesh model) is between 0 and 90 degrees, then record the number of triangle facests in the target virtual object mesh model that meet this angle. If there are multiple triangle facests, then the vertex is located in the geometric space of the target virtual object mesh model.

[0108] 4. For any triangular facet of any scene object mesh model, if its three vertices are all located within the geometric space of the target virtual object mesh model, and its mass point is also located within the geometric space of the target virtual object mesh model, then the triangular facet is completely located within the geometric space of the target virtual object mesh model.

[0109] 5. Cache the triangle patches selected in step 4 and delete them. Group the remaining models and center the anchor points of the models using center pivot to obtain an updated scene mesh model that has been batch optimized.

In the rightmost graphic c, the black parts are the deleted faces.

[0111] It is understood that the embodiments of this application provide a visual operation interface to facilitate users in selecting models for face reduction processing. By deleting occluded or hidden faces during model combination, the number of facets of the model is reduced, thereby reducing the resource consumption during rendering of the combined model.

[0112] This embodiment also provides a scene model processing device, which can be integrated into an electronic device, such as a computer device, which can be a terminal, server or other device.

[0113] For example, in this embodiment, the method of this application embodiment will be described in detail using a specific integrated terminal of the scene model processing device as an example.

[0114] For example, such as Figure 6 As shown, the scene model processing device may include:

[0115] The acquisition module 1001 is used to acquire a scene mesh model, wherein the scene mesh model is obtained by combining at least two scene object mesh models;

[0116] The space determination module 1002 is used to determine the target virtual object mesh model for screening patches from the scene object mesh model, and to determine the geometric space occupied by the target virtual object mesh model in the scene mesh model according to the outline of the target virtual object mesh model.

[0117] The patch determination module 1003 is used to determine, for any scene object mesh model other than the target virtual object mesh model in the scene mesh model, the target patch contained in the geometric space of the scene object mesh model.

[0118] The deletion module 1004 is used to delete the target facet in the scene mesh model to obtain an updated scene mesh model.

[0119] In one example, the patch determination module 1003 includes:

[0120] The patch determination unit includes: determining, based on the geometric space, candidate patches in the mesh model of any scene object whose vertices are located in the geometric space, and taking the candidate patches whose corresponding particles are also located in the geometric space as target patches.

[0121] In one example, the target virtual object mesh model is a ground resource mesh model, and the patch determination element includes:

[0122] The first determining subunit is used to take the surface of the above-ground resource grid model as a reference surface and the surface of any scene object grid model as a surface to be processed.

[0123] The calculation subunit is used to calculate, for each facet to be processed, the angle between the line connecting the vertex of the facet to be processed and the vertex of each reference facet, and the normal vector of the corresponding reference facet.

[0124] The second determining subunit is used to take the reference surface as the surface to be counted if the included angles corresponding to the reference surface are all within the preset angle range.

[0125] The third determining subunit is used to count the number of face pieces to be counted corresponding to each face piece to be processed. If the number exceeds a preset number threshold, the face piece to be processed is taken as a candidate face piece.

[0126] In one example, the target virtual object mesh model is a terrain resource mesh model, and the spatial determination module 1002 includes:

[0127] A generation unit is used to generate a closed space at the bottom of the terrain resource grid model, with the surface containing the outline of the terrain resource grid model as the top surface.

[0128] A spatial determination unit is used to define the enclosed space as a geometric space.

[0129] In one example, the generating unit includes:

[0130] A control subunit is used to control at least two vertices on the edge of the terrain resource grid model to translate downwards, thereby generating the side surface of the closed space corresponding to the terrain resource grid model.

[0131] Aggregation sub-units are used to aggregate the vertices on the bottom edge of the side surface to generate the bottom surface of the closed space corresponding to the terrain resource grid model;

[0132] A sub-unit is generated, which is used to create a closed space by taking the surface where the outline of the terrain resource grid model is located as the top surface and enclosing it according to the top surface, the side surface and the bottom surface.

[0133] In one example, deleting module 1004 includes:

[0134] A Boolean operation unit is used to perform a Boolean subtraction operation on the geometric space and the mesh model of any scene object, deleting both the geometric space and the target face from the scene mesh model to obtain a local scene mesh model, which includes the newly generated bottom face of the mesh model of any scene object after the Boolean subtraction operation.

[0135] The deletion unit is used to delete the newly formed bottom surface from the local scene mesh model to obtain the transition scene mesh model;

[0136] The combination unit is used to recombine the terrain resource grid model into the transition scene grid model to obtain an updated scene grid model.

[0137] In one example, the module to be deleted also includes:

[0139] The deletion unit includes:

[0140] Delete the faces belonging to the target material to obtain the transition scene mesh model.

[0141] Using the apparatus in this embodiment, by determining the target virtual object mesh model for filtering faces and determining the geometric space occupied by the target virtual object mesh model, once faces of other scene object mesh models contained in this geometric space are determined, the filtering of target faces to be deleted is achieved, improving the efficiency of filtering invalid faces in the scene mesh model. By deleting the target face from the scene mesh model, the scene mesh model is optimized, reducing the number of faces required to be rendered during scene mesh model rendering, while also avoiding rendering of invalid faces, avoiding resource waste, and improving performance.

[0145] Obtain a scene mesh model, which is obtained by combining at least two scene object mesh models;

[0146] The target virtual object mesh model for filtering patches is determined from the scene object mesh model, and the geometric space occupied by the target virtual object mesh model in the scene mesh model is determined according to the outline of the target virtual object mesh model.

[0147] For any scene object mesh model other than the target virtual object mesh model in the scene mesh model, determine the target patch contained in the geometric space in the scene object mesh model.

[0148] The target facet in the scene mesh model is deleted to obtain the updated scene mesh model.

[0149] In one example, the step "determining the target patch contained in the geometry space of any scene object mesh model" includes:

[0150] Based on the geometric space, candidate faces of vertices in the mesh model of any scene object are determined, and candidate faces of the corresponding particles of the vertices that are also in the geometric space are taken as target faces.

[0152] The surface of the above-ground resource grid model is used as the reference surface, and the surface of any scene object grid model is used as the surface to be processed.

[0153] For each facet to be processed, calculate the angle between the line connecting the vertex of the facet to be processed and the vertex of each reference facet, and the normal vector of the corresponding reference facet.

[0154] If the included angles corresponding to the reference facets are all within the preset angle range, then the reference facets are used as facets to be counted.

[0155] The number of unprocessed face pieces corresponding to each unprocessed face piece is counted. If the number exceeds a preset threshold, the unprocessed face piece is considered a candidate face piece.

[0157] Using the surface containing the outline of the terrain resource grid model as the top surface, a closed space is generated at the bottom of the terrain resource grid model;

[0158] The enclosed space is taken as the geometric space.

[0160] Control at least two vertices on the edge of the terrain resource grid model to translate downwards, generating the side surface of the closed space corresponding to the terrain resource grid model;

[0161] The vertices on the bottom edge of the side surface are aggregated to generate the bottom surface of the closed space corresponding to the terrain resource grid model;

[0162] The top surface is the surface containing the outline of the terrain resource grid model, and a closed space is generated by enclosing the top surface, the side surface, and the bottom surface.

[0163] In one example, the step "delete the target patch from the scene mesh model to obtain an updated scene mesh model" includes:

[0164] Perform a Boolean subtraction operation on the geometric space and the mesh model of any scene object to delete both the geometric space and the target patch from the scene mesh model, thereby obtaining a local scene mesh model. The local scene mesh model includes the newly generated bottom surface of the mesh model of any scene object after the Boolean subtraction operation.

[0165] The newly formed bottom surface is deleted from the local scene mesh model to obtain the transition scene mesh model;

[0166] The terrain resource grid model is recombined into the transition scene grid model to obtain the updated scene grid model.

Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and then processed by processor 1101 before being transmitted via radio frequency circuit 1104 to, for example, another electronic device, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between peripheral headphones and electronic devices.
