In the prior art, there is a demand that virtual object models of different body shapes of the same virtual object need to wear the same set of virtual clothing; however, the existing method of making virtual clothing models of virtual clothing suitable for virtual object models of different body shapes requires game production personnel to manually make virtual clothing models of corresponding virtual clothing according to model information of virtual object models of different body shapes.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. At the same time, in the description of the embodiments of the present application, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] The embodiments of the present application provide a method, device, electronic device, and computer-readable storage medium for processing a virtual object model. Specifically, the present embodiment will be described from the perspective of a processing device for a virtual object model, and the processing device for the virtual object model can be specifically integrated in an electronic device, that is, the processing method for the virtual object model of the embodiment of the present application can be executed by an electronic device, and optionally, the electronic device can include: a terminal device. The terminal device can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop computer, a game console, or a personal computer (PC) and other devices.

[0027] The processing method of the virtual object model provided in the embodiment of the present application can be applied to a processing system of the virtual object model. The processing system of the virtual object model can include a player terminal device and a server, and the terminal can be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. The player terminal device and the server can perform two-way communication through a network.

[0028] Optionally, the server may be an independent server, or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of multiple servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0029] The processing method of the virtual object model in one embodiment of the present disclosure can be run on a local terminal device or a server. When the processing method of the virtual object model is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0030] For example, when the processing method of the virtual object model is run on the terminal, the terminal device stores a game application and is used to present a virtual scene in the game screen. The terminal device is used to interact with the user through a graphical user interface, for example, the game application is downloaded and installed by the terminal device and run. The terminal device may provide the graphical user interface to the user in a variety of ways, for example, it can be rendered and displayed on the display screen of the terminal device, or the graphical user interface is presented by holographic projection. For example, the terminal device may include a touch display screen and a processor, the touch display screen is used to present the graphical user interface and receive the operation instructions generated by the user acting on the graphical user interface, the graphical user interface includes a game screen, and the processor is used to run the game, generate a graphical user interface, respond to the operation instructions, and control the display of the graphical user interface on the touch display screen.

[0031] For example, when the processing method of the virtual object model runs on the server, it can be a cloud game. Cloud gaming refers to a gaming method based on cloud computing. In the operation mode of cloud gaming, the operating body of the game application and the game screen presentation body are separated, and the storage and operation of the processing method of the virtual object model are completed on the cloud gaming server. The game screen presentation is completed on the client of the cloud gaming. The cloud gaming client is mainly used for receiving and sending game data and presenting the game screen. For example, the cloud gaming client can be a display device with data transmission function close to the user side, such as a mobile terminal, a TV, a computer, a handheld computer, a personal digital assistant, etc., but the terminal device for processing game data is a cloud gaming server in the cloud. When playing the game, the user operates the cloud gaming client to send an operation instruction to the cloud gaming server. The cloud gaming server runs the game according to the operation instruction, encodes and compresses the game screen and other data, and returns it to the cloud gaming client through the network. Finally, the cloud gaming client decodes and outputs the game screen.

[0032] See also Figure 1 , Figure 1A scene diagram of a processing system for a virtual object model provided by an embodiment of the present application. The system may include at least one terminal, at least one server, at least one database, and a network. The terminal held by the user can be connected to the server of different games through the network. The terminal is any device with computing hardware that can support and execute software products corresponding to the game. In addition, when the system includes multiple terminals, multiple servers, and multiple networks, different terminals can be connected to each other through different networks and different servers. The network can be a wireless network or a wired network, such as a wireless network such as a wireless local area network (WLAN), a local area network (LAN), a cellular network, a 2G network, a 3G network, a 4G network, a 5G network, etc. In addition, different terminals can also use their own Bluetooth network or hotspot network to connect to other terminals or to servers, etc. For example, multiple users can be online through different terminals and connected and synchronized with each other through appropriate networks to support multi-player games. In addition, the system may include multiple databases, multiple databases are coupled to different servers, and information related to the game environment can be continuously stored in the database when different users are online for multi-player games.

[0033] The embodiment of the present application provides a method for processing a virtual object model, which can be executed by a terminal or a server. The embodiment of the present application takes the method for processing a virtual object model executed by a terminal as an example for explanation. Among them, the terminal may include a touch display screen and a processor (of course, the terminal may also use peripherals such as a mouse and a keyboard as input devices, and only the touch display screen is used as an example for explanation here), and the touch display screen is used to present a graphical user interface and receive operation instructions generated by the user acting on the graphical user interface. When the user operates the graphical user interface through the touch display screen, the graphical user interface can control the local content of the terminal by responding to the received operation instructions, and can also control the content of the opposite server by responding to the received operation instructions. For example, the operation instructions generated by the user acting on the graphical user interface include instructions for starting a game application, and the processor is configured to start the game application after receiving the instructions for starting the game application provided by the user. In addition, the processor is configured to render and draw a graphical user interface associated with the game on the touch display screen. The touch display screen is a multi-touch sensitive screen that can sense touch or sliding operations performed simultaneously by multiple points on the screen. The user uses a finger to perform a touch operation on the graphical user interface, and when the graphical user interface detects the touch operation, different virtual objects in the graphical user interface of the game are controlled to perform actions corresponding to the touch operation.

[0034] It should be noted that Figure 1The scenario diagram of the processing system of the virtual object model shown is merely an example. The processing system and scenario of the virtual object model described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0035] The embodiment of the present application provides a method for processing a virtual object model, which can be executed by a terminal or a server. The embodiment of the present application takes the method for processing a virtual object model executed by a terminal as an example for explanation, and a graphical user interface can be provided by a terminal device, and the graphical user interface includes at least part of a virtual scene, and a controlled virtual object located in the virtual scene and controlled by the terminal device. The graphical user interface, virtual scene, and virtual object are explained below.

[0036] The game scene (or virtual scene) is a virtual scene displayed (or provided) when the application is running on a terminal or server. Optionally, the virtual scene is a simulation environment of the real world, or a semi-simulation and semi-fictitious virtual environment, or a purely fictitious virtual environment. The virtual scene is any one of a two-dimensional virtual scene and a three-dimensional virtual scene, and the virtual environment can be the sky, land, ocean, etc., wherein the land includes environmental elements such as deserts and cities. Among them, the virtual scene is a scene with complete game logic of virtual objects such as user control. For example, for sandbox 3D shooting games, the virtual scene is a 3D game world for players to control virtual objects to fight. Example virtual scenes may include: at least one element of mountains, plains, rivers, lakes, oceans, deserts, skies, plants, buildings, and vehicles; for example, for 2D card games, the virtual scene is a scene for displaying released cards or displaying virtual objects corresponding to cards. Example virtual scenes may include: an arena, a decisive battlefield, or other "field" elements or other elements that can display the status of card battles; for 2D or 3D multiplayer online tactical competitive games, the virtual scene is a 2D or 3D terrain scene for virtual objects to fight. Example virtual scenes may include: canyon-style mountains, lines, rivers, classrooms, tables and chairs, podiums and other elements.

[0037] The graphical user interface is obtained by executing a software application on a processor of a mobile terminal or other terminal and rendering it on a display, and can be a display screen interface of a terminal device. The graphical user interface can present the entire game scene, or only a part of the game scene. The game scene includes multiple static virtual objects, specifically including ground, mountains, rocks, vegetation, buildings, etc. When the game scene is relatively large, only the local content of the game scene is displayed on the graphical user interface of the terminal device during the game. Optionally, the game scene contains game characters, which can be game characters controlled by players, or NPCs (abbreviation of Non-Player Character, which is a type of character in the game, meaning non-player characters), which is not limited in this exemplary embodiment. The graphical user interface can include a UI interface and a game screen for players to interact. In an optional embodiment, the UI interface can include game controls (such as skill controls, mobile controls, function controls, etc.), indicator signs (such as direction indicator signs, role indicator signs, etc.), information display areas (such as the number of kills, game time, etc.), or game setting controls (such as system settings, stores, gold coins, etc.). In an optional implementation, the game screen is a display screen corresponding to a virtual scene displayed by a terminal device, and the game screen may include virtual objects such as game characters, NPC characters, AI characters, etc. that execute game logic in the virtual scene.

[0038] A game object (or virtual object, game character) refers to a dynamic object that can be controlled in a virtual scene. Optionally, the dynamic object can be a virtual character, a virtual animal, a cartoon character, etc. The virtual object is a character controlled by a player through an input device, or an artificial intelligence (AI) set in a virtual environment battle through training, or a non-player character (NPC) set in a virtual scene battle. Optionally, the virtual object is a virtual character competing in a virtual scene. Optionally, the number of virtual objects in the virtual scene battle is preset, or is dynamically determined according to the number of clients joining the battle, and the embodiment of the present application does not limit this. In a possible implementation, the user can control the virtual object to move in the virtual scene, for example, control the virtual object to run, jump, crawl, etc., and can also control the virtual object to use the skills, virtual props, etc. provided by the application to fight with other virtual objects. (Game) props refer to props that can be used by virtual objects in a virtual environment, including but not limited to firearms, cold weapons, grenades, shields, springboards, puppets, etc., which can be used by virtual objects to speed up their own attributes, assist in combat, or launch damage to other virtual objects. Virtual props can also be supply props such as bullets, and can also be equipped on designated virtual weapons for accessories such as extended magazines, aiming scopes, flash suppressors, and stocks. The virtual camera is a necessary component for the game scene screen, which is used to present the game scene screen. A game scene corresponds to at least one virtual camera. According to actual needs, there can be two or more virtual cameras, which serve as the game rendering window to capture and present the game world's screen content to the player. By setting the parameters of the virtual camera, the player's perspective of viewing the game world can be adjusted, such as the first-person perspective and the third-person perspective.

[0039] The following is a detailed description in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0040] See also Figure 2 , Figure 2 A flowchart of a method for processing a virtual object model provided in an embodiment of the present application is shown. The specific flow of the method for processing a virtual object model may include steps 101 to 104 as follows:

[0041] Step 101: Obtain a first virtual object model.

[0042] Specifically, the game production personnel can obtain a first virtual object model of a virtual object of a first body shape, wherein the first virtual object model includes a first object mesh model and a corresponding first object skeleton model. Among them, the mesh model is a basic model of the virtual object model, which is composed of a series of vertices (Vertex), edges (Edge) and faces (Face). These vertices, edges and faces together form a three-dimensional mesh structure, which is used to represent the shape and appearance of the virtual object. Therefore, the mesh model can accurately represent the shape and details of the virtual object. The mesh model allows various editing operations on vertices, edges and faces, such as displacement, scaling, rotation, etc., so that the shape and posture of the virtual object can be easily adjusted, so that a highly realistic effect can be achieved by adjusting the position of the vertices and the shape of the face. The mesh model is suitable for modeling various virtual objects, such as virtual characters, virtual animals, virtual buildings, and virtual vehicles. The skeleton model is a model used to drive the action and form of the virtual object, which is composed of a series of bones (Bone). These bones are connected by joints (Joint) to form a complete skeleton system. The skeleton model is usually used in combination with the mesh model to achieve the animation effect of the virtual object. Game developers can easily control the posture and movement of virtual objects by adjusting the position, rotation, and scaling of virtual bones in the skeletal model. Therefore, the skeletal model can simulate the movement of organisms in the real world, making the movement of virtual objects more natural and realistic. Furthermore, the skeletal model supports adding new bones and joints to accommodate virtual objects of different shapes and sizes.

[0043] Furthermore, the mesh model and the skeleton model can be bound together by setting skinning data, which is data indicating the association between the vertices of the mesh model and the bones in the skeleton model. The skinning data determines how the mesh model (i.e., the "skin") deforms as the virtual bones in the skeleton model move. The skinning data is a set of information that defines the association between the vertices of the mesh model and the corresponding virtual bones in the skeleton model. Specifically, each vertex is assigned one or more bone influence weights, which determine how the vertex moves with the movement of the bones during the animation. When the virtual bones are transformed (such as rotated or translated), the vertices of the mesh model are interpolated based on these weights and the transformation of the bones to obtain new vertex positions, thereby realizing the deformation of the mesh model.

[0044] Step 102: Acquire a first virtual clothing model that matches the body shape of the first virtual object model.

[0045] The first virtual clothing model includes a first clothing mesh model and a corresponding first clothing skeleton model.

[0046] In an embodiment of the present application, a game producer can make a first virtual clothing model based on the specified virtual clothing information and the first object skeleton model of the first virtual object model. Specifically, the game producer can manually make a complete set of first clothing mesh models that match the body shape of the first virtual object model according to the specified virtual clothing information. At the same time, in order to determine the skeleton and skinning effects, a set of first clothing skeleton models and first clothing mesh models will also be manually built for skinning operations. The first clothing skeleton model is based on the first object skeleton model and is made according to the requirements of the first clothing mesh model. The set of first clothing skeleton models contains bone (Bone) information, and is combined with the first clothing mesh model to obtain a first virtual clothing model containing skinning information. The first virtual clothing model also includes a first clothing mesh model, a corresponding first clothing skeleton model and skinning information.

[0047] Step 103: Adjust the first virtual object model to obtain a second virtual object model, wherein the first virtual object model and the second virtual object model are virtual object models of different sizes.

[0048] The second virtual objects corresponding to the first virtual object and the second virtual object models are virtual objects with the same target object attributes but different body shapes. For example, the first virtual object and the second virtual object are both female, the first virtual object is a female with a normal body shape, and the second virtual object is a female with a fat body shape. The first virtual object model can be a virtual model of a virtual object with a standard body shape. The standard body shape is a basic template for creating multiple variant characters in game character design. It provides a unified reference point for developing character variants with different body shapes and appearances.

[0049] In one embodiment, the first virtual object model may be adjusted in size to obtain the second virtual object model.

[0050] Specifically, the shape information of the body types corresponding to the first virtual object, the second virtual object, and the third virtual object can be obtained according to the maximization file information. By expanding the body type of the first virtual object, the second virtual object and the third virtual object can be manually deformed into different body types without adding or deleting vertices, thereby completing the production of virtual objects of different body types.

[0051] Specifically, the step of “adjusting the first virtual object model to obtain the second virtual object model” includes:

[0052] The first virtual object model is expanded and / or reduced to obtain a second virtual object model.

[0053] Specifically, if the first virtual object model corresponds to a normal body shape, the first virtual object model may be expanded to obtain a second virtual object model of a fat body shape; and the first virtual object model may be reduced to obtain a second virtual object model of a thin body shape.

[0054] Furthermore, the step of “inflating and / or shrinking the first virtual object model to obtain a second virtual object model” includes:

[0055] Performing a process of enlarging or reducing vertex positions of the first object mesh model to obtain a second object mesh model;

[0056] Enlarging or reducing the vertex positions of the first object skeleton model to obtain a second object skeleton model;

[0057] A second virtual object model is generated based on the second object mesh model and the second object skeleton model.

[0058] Specifically, the vertex positions of the first object mesh model and the first object skeleton model may be enlarged or reduced, so that the first virtual object model can be changed into a second virtual object model of a different size without adding, deleting or modifying vertices.

[0059] Step 104: Based on the model mapping relationship between the first virtual object model and the first virtual clothing model, and the second virtual object model, the first virtual clothing model is deformed to obtain a second virtual clothing model matching the second virtual object.

[0060] In one embodiment, the step of “before deforming the first virtual clothing model based on the model mapping relationship between the first virtual object model and the first virtual clothing model, and the second virtual object model, to obtain a second virtual clothing model matching the second virtual object” also includes:

[0061] A first model mapping relationship between the first object mesh model and the first clothing mesh model is obtained, and a second model mapping relationship between the first object skeleton model and the first clothing skeleton model is obtained.

[0062] In a specific embodiment, the step of “obtaining a first model mapping relationship between the first object mesh model and the first clothing mesh model” includes:

[0063] Using a preset radial basis function, obtaining a first correspondence between each object mesh vertex in the first object mesh model and a corresponding clothing mesh vertex in the first clothing mesh model;

[0064] Based on the first correspondence between each of the object mesh vertices and the corresponding clothing mesh vertices, a first model mapping relationship is determined.

[0065] Specifically, the radial basis function is used to obtain the correspondence between each vertex of the first clothing mesh model and each vertex of the first object mesh model and record it as wm; then, based on each vertex of the second object mesh model and the wm coefficient, the second clothing mesh model can be deformed on the basis of the first clothing mesh model.

[0066] Among them, the radial basis function is a real-valued function whose value depends only on the distance from the origin, that is, Φ(x)=Φ(‖x‖), or it can also be the distance to any point c, point c is called the center point, that is, Φ(x, c)=Φ(‖xc‖). Any function Φ that satisfies the characteristic of Φ(x)=Φ(‖x‖) is called a radial basis function. The standard generally uses the Euclidean distance (also called the Euclidean radial basis function). The radial basis function used in the embodiment of the present application is specifically as follows:

[0067] The mesh model used is: Φ(x,y,z)=log10(d(x,y,z)+1.0), where d is the squared distance difference between the vertices of woman01's body shape;

[0068] The skeleton model uses: np.exp(-(d / sigma)**2), where d is the sum of the squares of x\y\z of woman01's reference skeleton position.

[0069] In another specific embodiment, the step of “obtaining a second model mapping relationship between the first object skeleton model and the first clothing skeleton model” includes:

[0070] Using a preset radial basis function, obtaining a second correspondence between each virtual object skeleton in the first object skeleton model and a corresponding virtual clothing skeleton in the first clothing skeleton model;

[0071] Based on the second corresponding relationship between each virtual object skeleton and the corresponding virtual clothing skeleton, a second model mapping relationship is determined.

[0072] Specifically, the radial basis function is used to obtain the correspondence between each bone (position, length) in the first clothing skeleton model and each bone (position, length) in the first object skeleton model and recorded as wb; then, based on each bone (position, length) and the wb coefficient of the second object skeleton model, the second clothing skeleton model can be deformed on the basis of the first clothing skeleton model.

[0073] Furthermore, the step of “deforming the first virtual clothing model based on the model mapping relationship between the first virtual object model and the first virtual clothing model, and the second virtual object model to obtain a second virtual clothing model matching the second virtual object” includes:

[0074] Based on the first model mapping relationship, the second model mapping relationship, the second object mesh model, and the second object skeleton model, respectively deforming the first clothing mesh model and the first clothing skeleton model to obtain a second clothing mesh model and a second clothing skeleton model matching the second virtual object;

[0075] A second virtual clothing model is generated based on the second clothing mesh model and the second clothing skeleton model.

[0076] Specifically, the step of "deforming the first clothing mesh model and the first clothing skeleton model respectively based on the first model mapping relationship, the second model mapping relationship, the second object mesh model, and the second object skeleton model to obtain a second clothing mesh model and a second clothing skeleton model matching the second virtual object" includes:

[0077] Based on the first model mapping relationship and the second object mesh model, deforming the first clothing mesh model to obtain a second clothing mesh model matching the second virtual object;

[0078] Based on the second model mapping relationship and the second object skeleton model, the first clothing skeleton model is deformed to obtain a second clothing skeleton model matching the second virtual object.

[0079] Furthermore, the step of “generating a second virtual clothing model based on the second clothing mesh model and the second clothing skeleton model” includes:

[0080] Acquire target skinning information of the first virtual clothing model, where the target skinning information is used to indicate a mapping relationship between the first clothing mesh model and the corresponding first clothing skeleton model for binding setting;

[0081] Based on the target skin information, the second clothing mesh model and the second clothing skeleton model are bound and set to obtain a second virtual clothing model.

[0082] In the embodiment of the present application, since the second virtual clothing model is in the process of making the second clothing mesh model and the second clothing skeleton model, the mesh model aspect ensures the consistency of the vertex semantics of the components of the first clothing mesh model and the second clothing mesh model, and the skeleton model (i.e., the skeleton) aspect ensures the consistency of the first clothing skeleton model and the second clothing skeleton model in bone sorting, naming, and parent-child structure. Since the definition of skinning is the correspondence between the bones of the skeleton model and the vertices of the mesh model, the skinning information of the first virtual clothing model can be directly reused on the second virtual clothing model, and the binding between the second clothing mesh model and the second clothing skeleton model can be completed. That is, the target skinning data of the first virtual clothing model can be used to bind the second clothing mesh model and the second clothing skeleton model to obtain the second virtual clothing model.

[0083] The skinning information may be skinning data, which is data for associating the vertices of the mesh model with the bones of the skeleton model. Specifically, the skinning process is to bind the vertices of the mesh model to the bones of the skeleton model so that a binding relationship is established between the vertices of the mesh model and the bones of the skeleton model, so that when the bones move, the mesh model can be deformed accordingly. The skinning data includes information such as vertex weights and bone influences, which determine which bones each vertex is affected by and the degree of the influence.

[0084] Based on the above introduction, the following example will be used to further illustrate the processing method of the virtual object model of the present application. The specific embodiment of the processing method of the virtual object model is as follows:

[0085] (1) In the embodiment of the present application, the game production personnel can manually produce a complete set of first clothing mesh models that match the body shape of the first virtual object model according to the specified virtual clothing information. At the same time, in order to determine the skeleton and skinning effects, a set of first clothing skeleton models and first clothing mesh models will also be manually constructed for skinning operations. The first clothing skeleton model is based on the first object skeleton model and is produced according to the requirements of the first clothing mesh model. The set of first clothing skeleton models contains bone (Bone) information, and is combined with the first clothing mesh model to obtain a first virtual clothing model containing skinning information. The first virtual clothing model also includes the first clothing mesh model, the corresponding first clothing skeleton model and the skinning information.

[0086] (2) The embodiment of the present application can expand the first object mesh model of the first virtual object model of the thin body to obtain the second object mesh model of the second virtual object model of the fat body, and the third object mesh model of the third virtual object model of the fattest body, and ensure that the second virtual object model, the third virtual object model and the first virtual object model are consistent in vertex semantics, that is, the vertex sorting order of the model is consistent. The core meaning of vertex semantics is that the model vertex IDs of the first virtual object model, the second virtual object model and the third virtual object model at the same relative position are consistent, that is, the vertex sorting is in the same sequential position in the overall vertex system of the model.

[0087] At the same time, the first object skeleton model of the first virtual object model is used to copy and adjust the second object skeleton model of the second virtual object model and the third object skeleton model of the third virtual object model in turn, so as to ensure that the second object skeleton model, the third object skeleton model and the first object skeleton model are consistent in the number of bones, the hierarchical structure and the naming of bones. Among them, the position information of the bones is part of the adjustment. In addition, the naming of bones in the same position (for example, the same scapula bones) needs to be consistent, the parent-child relationship between bones (i.e., the hierarchical structure) needs to be consistent, and the number of bones between the skeleton (i.e., the object skeleton model) and the skeleton needs to be consistent.

[0088] (3) The embodiment of the present application can use the radial basis function, and the correspondence between each vertex of the first clothing mesh model and each vertex of the first object mesh model is recorded as wm, and this correspondence is passed to other expanded body models (i.e., the second object mesh model of the second virtual object model, and the third object mesh model of the third virtual object model) through vertex semantics, so as to realize the automatic adaptation of fashion parts, so as to obtain the second clothing mesh model of the second virtual object model and the third clothing mesh model of the third virtual object model. Specifically, based on each vertex and wm coefficient of the second object mesh model, the second clothing mesh model can be deformed on the basis of the first clothing mesh model; based on each vertex and wm coefficient of the third object mesh model, the third clothing mesh model can be deformed on the basis of the first clothing mesh model.

[0089] After obtaining the second clothing mesh model and the third clothing mesh model, the radial basis function is used to obtain the corresponding relationship between each bone (position, length) in the first clothing skeleton model and each bone (position, length) of the first object skeleton model and record it as wb, and pass this corresponding relationship to the adjusted other body part bones (i.e., the second object skeleton model of the second virtual object model and the third object skeleton model of the third virtual object model) through the skeleton information, so as to realize the automatic adaptation of the fashion skeleton and obtain the second clothing skeleton model of the second virtual object model and the third clothing skeleton model of the third virtual object model. Specifically, based on each bone (position, length) and wb coefficient of the second object skeleton model, the second clothing skeleton model can be deformed on the basis of the first clothing skeleton model; based on each bone (position, length) and wb coefficient of the third object skeleton model, the third clothing skeleton model can be deformed on the basis of the first clothing skeleton model.

[0090] (4) After the above steps, the second virtual clothing model that matches the body shape of the second virtual object model and the third virtual clothing model that matches the body shape of the third virtual object model only need to automatically generate skin information, and the complete fashion resource production can be completed. Since the skin information records the mapping relationship between the model vertices of the mesh model and the skeleton model, the skin information can be reused when the model vertex semantics and the skeleton structure information are exactly the same. Therefore, when the second clothing mesh model and the second object skeleton model are skinned, the skin data of the first clothing mesh model and the first object skeleton model can be reused, and the skinning production of the second virtual clothing model can be realized; when the third clothing mesh model and the third object skeleton model are skinned, the skin data of the first clothing mesh model and the first object skeleton model (i.e., the first clothing skeleton model) can be reused, and the skinning production of the third virtual clothing model can be realized.

[0091] In summary, an embodiment of the present application provides a method for processing a virtual object model, by obtaining a first virtual object model; then, obtaining a first virtual clothing model that matches the body shape of the first virtual object model; then, adjusting the first virtual object model to obtain a second virtual object model, wherein the first virtual object model and the second virtual object model are virtual object models of different body shapes; finally, based on a model mapping relationship between the first virtual object model and the first virtual clothing model, and the second virtual object model, deforming the first virtual clothing model to obtain a second virtual clothing model that matches the second virtual object. According to the solution of the embodiment of the present application, a first virtual object model of a specified body shape is obtained, the body shape of the first virtual object model is adjusted to obtain a second virtual object model of a different body shape, and then, based on the model mapping relationship between the first virtual object model and the first virtual clothing model matching the body shape of the first virtual object model, and the second virtual object model, the first virtual clothing model is deformed to obtain a second virtual clothing model matching the second virtual object; thus, other virtual object models of body shapes different from the first virtual object model and the corresponding second virtual clothing models can be automatically generated based on a first virtual object model and the corresponding first virtual clothing model, which simplifies the steps of making virtual clothing models of virtual object models of different body shapes of the same virtual object, saves a lot of manpower and time, and improves the efficiency of making corresponding virtual clothing models for virtual object models.
