[0002] With the development of computer image processing technology and artistic capabilities as well as the improvement of gaming software computing power, the designs of virtual objects such as virtual characters, virtual items, virtual monsters and virtual props in various games, especially massively multiplayer online role-playing games (MMORPGs), are usually highly stylized, which can increase the fun of the game and meet the personalized requirements of players for virtual objects in the game.

[0003] At present, in order to meet the personalized requirements of players for virtual objects in games, it is usually necessary to take into account the diversity of the virtual object's entire body during the production of virtual object models, especially the diversity of facial features during the production of virtual character models. However, for different virtual objects, directly replacing the virtual object model will result in time-consuming and labor-intensive processing and high performance consumption. If the ratio between the virtual object block models is adjusted, the shape of the virtual object model cannot be changed, resulting in limited differentiation and personalization of the virtual object model, making it difficult to meet the diversified and personalized requirements of players for virtual objects in games.

[0057] In order to make the purpose, technical solution and beneficial effects of this application clearer, the technical solution in the embodiment of this application will be clearly and completely described below in conjunction with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0058] At present, in order to increase the fun of the game, the design of virtual objects such as virtual characters, virtual items, virtual monsters and virtual props in the game is usually highly stylized. Therefore, the diversity of virtual objects usually needs to be considered in the process of virtual object model making. However, the current virtual object model making is usually time-consuming, labor-intensive and performance-intensive, and it is difficult to meet players' diverse and personalized needs for virtual objects in the game.

[0059] To this end, in an embodiment of the present application, each reference model that has a seam relationship with the target virtual object block model of the part to be replaced is determined from each reference model of the reference virtual object as the target reference model, and the edge vertices of the target virtual object block model are matched with the edge vertices of each target reference model to obtain each edge vertex group; the normal information of at least two edge vertices contained in each edge vertex group is unified to obtain the target normal information of the edge vertices represented by each edge vertex group; based on the target normal information of the edge vertices represented by each edge vertex group, the reference virtual object block model of the part to be replaced in the reference virtual object model is replaced with the target virtual object block model to obtain the target virtual object model.

[0060] In this way, by determining from the various benchmark models of the benchmark virtual object that have a seam relationship with the target virtual object block model of the part to be replaced as the target benchmark models, and unifying the normal information of the edge vertices at the seams between the target virtual object block model and the target benchmark models, the normal directions of the edge vertices at the seams can be standardized, so that the virtual object block models of different parts can be seamlessly switched without affecting the light and shadow effects of the target virtual object model finally obtained, and then the virtual object block models of each component can be freely switched according to the actual game needs, so that the aesthetic needs and matching freedom of the players can be met to a greater extent, and the diversification and personalization of virtual objects in the game can be realized.

[0061] After introducing the application scenarios and design concepts of the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described in detail below.

[0062] The embodiment of the present application provides a method for generating a virtual object model in a game, which can be applied to electronic devices such as computing devices and user terminals, wherein the computing devices include but are not limited to servers, virtual machines, etc., and the user terminals include but are not limited to mobile phones, tablet computers, PDAs, laptop computers, desktop computers, etc. Figure 1 As shown, the general process of the method for generating a virtual object model in a game provided by the embodiment of the present application is as follows:

[0063] Step 101: Acquire each reference model of a reference virtual object; wherein each reference model includes a reference virtual object model of the reference virtual object and reference virtual object block models corresponding to different parts of the reference virtual object model.

[0064] In a specific implementation, when the electronic device obtains each reference model of the reference virtual object, it can adopt but is not limited to the following methods:

[0065] The first method: the electronic device determines any virtual object model of a baseline virtual object as a baseline virtual object model; splits the baseline virtual object model according to different parts to obtain baseline virtual object block models corresponding to different parts of the baseline virtual object model; and composes each baseline model of the baseline virtual object based on the baseline virtual object model and the baseline virtual object block models corresponding to different parts.

[0066] The second method: the electronic device splits the virtual object block models corresponding to different parts from at least two virtual object models of the reference virtual object, and unifies the normal information of the edge vertices at the seams between the virtual object block models corresponding to the different parts to obtain the reference virtual object block models corresponding to the different parts; reorganizes the reference virtual object block models corresponding to the different parts to obtain the reference virtual object model; and composes each reference model of the reference virtual object based on the reference virtual object model and the reference virtual object block models corresponding to the different parts.

[0067] It is worth mentioning that the electronic device can also use any of the above methods to obtain the various benchmark models of the benchmark virtual object in advance, and save the various benchmark models of the benchmark virtual object to a designated storage area (such as a database, memory, etc.), so that when obtaining the various benchmark models of the benchmark virtual object, they can be directly obtained from the designated storage area.

[0068] Step 102: Determine the target virtual object block model corresponding to the part to be replaced, and determine, from among the reference models, each reference model that has a seam relationship with the target virtual object block model as a target reference model.

[0069] During specific implementation, after the electronic device determines the target virtual object block model corresponding to the part to be replaced, it can determine, from each benchmark model, the benchmark models that have a seam relationship with the target virtual object block model corresponding to the part to be replaced as the target benchmark models based on the pre-saved seam relationship between the different parts and each benchmark model.

[0070] Step 103: Match the edge vertices of the target virtual object block model with the edge vertices of each target reference model to obtain edge vertex groups; wherein each edge vertex group includes at least two edge vertices, at least two edge vertices belong to the target virtual object block model and each target reference model respectively, and at least two edge vertices overlap with each other at the seam between the target virtual object block model and each target reference model.

[0071] In a specific implementation, the electronic device may first filter out the edge vertices of the target virtual object block model from the vertices of the target virtual object block model based on the number of connection faces of the vertices of the target virtual object block model, and for each target reference model, filter out the edge vertices of the target reference model from the vertices of the target reference model based on the number of connection faces of the vertices of the target reference model; then, for each edge vertex of the target virtual object block model, the edge vertices of the target virtual object block model and the edge vertices of each target reference model that are closest to the edge vertices of the target virtual object block model are formed into an edge vertex group, and / or the edge vertices of the target virtual object block model and the edge vertices of each target reference model that are at the same position as the edge vertex of the target virtual object block model are formed into an edge vertex group.

[0072] Step 104: for each edge vertex group, normal information of at least two edge vertices included in the edge vertex group is unified to obtain target normal information of the edge vertices represented by the edge vertex group.

[0073] In a specific implementation, the electronic device may average the normal information of at least two edge vertices included in each edge vertex group to obtain the target normal information of the edge vertices represented by the edge vertex group. For example, the average value of the normal information of at least two edge vertices included in the edge vertex group is determined as the target normal information of the edge vertices represented by the edge vertex group; or in another example, the weighted average value of the normal information of at least two edge vertices included in the edge vertex group is determined as the target normal information of the edge vertices represented by the edge vertex group.

[0074] Step 105: Based on the target normal information of the edge vertices represented by each edge vertex group, the reference virtual object block model of the to-be-replaced part in the reference virtual object model is replaced with the target virtual object block model to obtain the target virtual object model.

[0075] In a specific implementation, the electronic device can replace the baseline virtual object block model of the to-be-replaced part in the baseline virtual object model with the target virtual object block model, and based on the target normal information of the edge vertices represented by each edge vertex group, update the normal information of each edge vertex at the joint between the target virtual object block model and each target baseline model to obtain the target virtual object model.

[0076] Generally speaking, in MMORPG, players have high requirements for the personalization and diversity of virtual characters. Therefore, the diversity of facial features needs to be considered in the design process of virtual character models. Different virtual character models can be generated through face pinching technology. In practical applications, the virtual character model generation methods based on face pinching technology include the following two methods:

[0077] The first method: Change the facial skin by binding bones, divide the face into multiple partitions, and use the slider controller to control the displacement position of the partition bones, thereby affecting the corresponding area of ​​the skin model. The partition bone displacement operation during the face pinching process generates the partition bone change value, and then superimposes the initial matrix of the default bone to achieve a secondary change;

[0078] The second method: Use fusion deformation to control subtle changes in face pinching. By making different deformations of the same face and controlling the parameters, the position of the point changes transitionally in the parameters of different deformed faces. This method is often used to create exaggerated expressions of virtual characters. Through a series of target shape objects, the basic object can obtain a very smooth and high-precision deformation effect.

[0079] However, the above two methods of generating virtual character models usually have the following defects: 1. In order to prevent deformation through the model, some games will sacrifice the degree of freedom, making it difficult to make a variety of reasonable deformations, and the degree of detail of joint adjustment is limited; 2. Bone face pinching is suitable for characters with realistic appearance, and cannot achieve stylized production; 3. Extreme pulling of bones will cause the problem of model deformation and angularity; 4. When using fusion deformation to control subtle changes in face pinching, each deformation requires adding an entire head, which consumes a lot of resources and performance.

[0080] To this end, as one of the virtual object models, the virtual character model can be generated by the in-game virtual object model generation method provided in the embodiment of the present application, thereby achieving seamless switching of virtual character block models of different parts without affecting the light and shadow effects of the virtual character model, and then freely switching the virtual character block models of each component according to actual game requirements, thereby satisfying the players' aesthetic needs and matching freedom to a greater extent, and realizing the diversification and personalization of virtual characters in the game.

[0081] Specifically, in the embodiment of the present application, the virtual character model can be a full-body model of the virtual character, and different parts can include but are not limited to feet, calves, knees, thighs, torso, arms, neck, face, etc. The virtual character model can also be a face model of the virtual character, and different parts can include but are not limited to face, eye sockets, nose, mouth, ears. Based on this, the following takes the virtual character model as an example to further describe the method for generating a virtual object model in the game provided in the embodiment of the present application, see Figure 2As shown, the specific process of the method for generating a virtual object model in a game provided by the embodiment of the present application is as follows:

[0082] Step 201: Acquire each reference face model of the reference virtual character from a designated storage area; wherein each reference face model includes a reference face overall model, a reference eye socket block model, a reference nose block model, a reference mouth block model, and a reference ear block model of the reference virtual character.

[0083] Step 202: Determine the facial block model corresponding to the part to be replaced; wherein the facial block model includes an eye socket block model, a nose block model, a mouth block model, and an ear block model.

[0084] Step 203: Determine, from among the reference facial models of the reference virtual character, the reference facial models that are connected to the eye socket block model as target reference facial models; wherein the target reference facial models include a reference facial overall model, a reference nose block model, and a reference ear block model.

[0085] Step 204: based on the number of connected faces of each vertex of the reference facial overall model, filter out edge vertices of the reference facial overall model from each vertex of the reference facial overall model; and based on the number of connected faces of each vertex of the orbital block model, filter out edge vertices of the orbital block model from each vertex of the orbital block model.

[0086] Step 205: For each edge vertex of the target orbital block model, the edge vertex of the orbital block model and the edge vertices of the reference facial model that are closest to and have the same position as the edge vertex of the orbital block model are combined to form an edge vertex group at the seam between the orbital block model and the reference facial model.

[0087] Step 206: for each edge vertex group at the seam between the orbital block model and the reference facial overall model, average the normal information of the two edge vertices included in the edge vertex group to obtain target normal information of the edge vertices represented by the edge vertex group.

[0088] Step 207: Based on a method similar to steps 204-206, obtain the target normal information of the edge vertices represented by each edge vertex group at the seam between the orbital block model and the reference nose block model, and the target normal information of the edge vertices represented by each edge vertex group at the seam between the orbital block model and the reference ear block model.

[0089] Step 208: Accumulate and merge target normal information of edge vertices represented by edge vertex groups at the seams between the eye socket block model and the reference face overall model, the reference nose block model, and the reference ear block model to obtain a target eye socket block model.

[0090] Step 209: Based on a method similar to steps 203 to 208, the normal information of each edge vertex at the seam of the nose block model, the mouth block model and the ear block model is processed to obtain the target nose block model, the target mouth block model and the target ear block model.

[0091] Step 210: The target eye socket block model, the target nose block model, the target mouth block model and the target ear block model are cumulatively combined to obtain the target virtual character face model.

[0092] Based on the above embodiments, the embodiments of the present application provide a virtual object model generation device, which can be applied to electronic devices such as computing devices and user terminals, wherein computing devices include but are not limited to servers, virtual machines, etc., and user terminals include but are not limited to mobile phones, tablet computers, PDAs, laptop computers, desktop computers, etc. For details, see Figure 3 As shown, the device 300 for generating a virtual object model in a game provided by an embodiment of the present application at least includes:

[0105] For each edge vertex of the target virtual object block model, the edge vertices of the target virtual object block model and the edge vertices of each target reference model that are closest to the edge vertex of the target virtual object block model are formed into an edge vertex group.
