In this embodiment, a virtual scene is taken as an example of a game scene.

Step S204, searching a target feature library from a first material library according to the role types, wherein the first material library comprises a plurality of sets of feature libraries, and each set of feature library corresponds to one role type;

before searching the target feature library from the first material library according to the role type, the scheme of the embodiment further includes: a feature library is configured for each character type in the virtual game, and the mapping relation between the character type and the feature library can be configured through an index table and the like.

Optionally, in the virtual game scene, the role type represents a classification to which the role belongs, and may be an attribute type of the first virtual role, such as species, race, occupation, level, group, and the like; for another example, in the virtual teaching scenario, the character type is an attribute type (or called identity type) of the first virtual character, such as a student, a teacher, a parent, and the like. Each feature library including the target feature library comprises a plurality of feature materials, the feature materials form a feature material set, the feature materials can be organs of virtual characters, parts on the organs, ornamentations and other elements capable of changing the image of the first character, and the feature materials are the minimum units of machine rendering.

And step S206, calling a basic body of the role model, and adjusting the basic body by adopting the target feature library to generate a first role image of the first virtual role, wherein the basic body is a basic body which is universal for all role types.

In this embodiment, the basic body may be a model common to character types, and may have a binding common skeleton, and have corresponding common materials, such as a head, a torso, and the like that each character type may have.

Determining the role type of the first virtual role through the steps; searching a target feature library from a first material library according to role types, wherein the first material library comprises a plurality of sets of feature libraries, each set of feature library corresponds to one role type, calling a basic body of a role model, and adjusting the basic body by adopting the target feature library to generate a first role image of a first virtual role, wherein the basic body is a basic body universal for all role types, the target feature library is searched from the first material library according to the role types, different feature libraries are configured for different role types, the first role images of different types can be configured on the same basic body, differentiation among different role types is realized through different feature libraries, the technical problem of low configuration efficiency of the first role image in the related technology is solved, the model resource amount loaded by a terminal is reduced, and the memory is reduced.

Optionally, the role classification to which the first virtual role belongs may be determined according to the role identity corresponding to the first virtual role, and the role classification is used as the role type of the first virtual role, where there is a difference in the roles under different role classifications, for example, the classifications of race, occupation, and the like.

In some scenarios, determining the role type of the first virtual role comprises: acquiring ethnic attribute information of a first virtual role; and determining the race type of the first virtual role according to the race attribute information, and taking the race type as the role type. In addition, the occupation type under the ethnic type can be further obtained, and the occupation attribute information of the first virtual role is obtained; the occupation type of the first virtual role is determined according to the occupation attribute information, the occupation type is used as the role type, besides race and occupation, a plurality of major classes and minor classes can be set in the embodiment, and then the role types are classified at different levels.

Alternatively, species types and the like may be used in addition to occupational types and ethnic types.

In one embodiment of this embodiment, the adjusting the basic body using the target feature library includes: receiving a first configuration instruction aiming at first-class materials, wherein the target feature library comprises the first-class materials which are special materials of the role type; calling first sub-models matched with the first type of materials based on a first configuration instruction, wherein each first type of material corresponds to one sub-model; and mounting the first sub-model on the basic body according to the preset mounting points.

In some examples, in the process of generating the first character image of the first virtual character, in order to reduce the configuration amount of the user, the server may automatically load materials necessary for several character images, for example, materials that eyes and mouth are all character types, and after the server calls the basic body of the character model, the server further includes: searching second-class materials, wherein the second-class materials are general materials of all role types; and loading a second type of material, optionally, mounting a second sub-model corresponding to the second type of material on the basic body, displaying the basic body on which the second sub-model is mounted on an image configuration interface, and further selecting a special material of the role type by a user to adjust the basic body so as to generate the role image.

Optionally, the first configuration instruction carries a first material identifier selected by the user.

In one example, the role type has corresponding default materials, for example, all roles under the role type have tails, and the tails can be the default materials of the role type, that is, the materials can be directly adopted without being selected by a user, so that when the user selects the role type, the sub-model corresponding to the default materials of the role type is directly mounted on the basic body.

In one embodiment, the first type of material is a dedicated material of a role type to which the first virtual role belongs, the second type of material is a general material of all role types, the first type of material includes material 1, material 2, and material 3, the material 1, the material 2, and the material 3 are respectively tail, hairstyle, and corner, the second type of material includes material 4, material 5, the material 4, and the material 5 are respectively eye and mouth, after the role type (the role type has default material 6), the basic body is displayed on the image configuration interface, the basic body has eye and mouth corresponding to the material 4 and the material 5, respectively, and the sub-model corresponding to the default material 6 of the role type is mounted. For example, a monkey family has a tail, which is the default material, and when the user selects the family, the child model of the tail is automatically mounted. The user can select the material 2 on the configuration interface, trigger a first configuration instruction, and mount the first sub-model on the top of the basic body by calling the hair style (namely the first sub-model) corresponding to the selected material 2, wherein the preset mounting point of the hair is the highest point of the top of the basic body, and other first-class materials and second-class materials can be further mounted on the basic body, so that the first role image with the role type of 'monkey' is generated.

The skeleton of the sub-model is also mounted on the skeleton of the basic body, so that the user can continue to adjust the part corresponding to the sub-model, in one example, the sub-model is the corner of the target role type, after the user selects the target role type, the corner adding or not adding can be displayed on the image configuration interface, and after the corner adding is selected, the sub-model of the corner is mounted on the basic body, and the skeleton of the sub-model is mounted on the basic body, so that the user can further specifically adjust the corner according to the skeleton of the sub-model.

The scheme of the embodiment can be applied to a face pinching system of a virtual game, and different feature libraries can be configured for different types of characters, for example, different ethnic feature libraries are configured for different ethnicities (human, demon, spirit, etc.), and feature materials of the ethnic feature library include a face, a trunk, four limbs, a tail, ornamentation, and the like. For example, different feature libraries are configured for different professions (such as soldiers, craftsmen, fishermen, and legal engineers), and corresponding hair style libraries can be configured specifically for different professions.

Fig. 3 is a schematic view of a hairstyle being mounted according to an embodiment of the present invention, wherein the left side is a schematic view of the basic body and the right side is a schematic view of the hairstyle being mounted.

In one embodiment, adjusting the base body using the target feature library includes: searching a target range parameter matched with the role type in a target feature library, wherein the target range parameter is used for indicating the adjustment range of a second type of material, the target range parameter is a special range parameter of the role type, the target feature library comprises the target range parameter of the second type of material, and the second type of material is a general material of all the role types; receiving a second configuration instruction aiming at the second type of materials; and adjusting the second type of materials within the adjusting range based on the second configuration instruction.

Optionally, the adjustment range may be, but is not limited to: range of amplitude, shape, orientation (e.g. spatial relationship of a material to the base body or to other materials, e.g. nostril may be up or down, opposite mouth, or vice versa), location of bone hanging points, etc. The adjustment range is taken as an amplitude range for example, and for a second type of material common to all character types, the adjustable amplitude range of each character type is different.

In this embodiment, for different role types, different zoom sizes are configured for each material in the second type of material, for example, the zoom size of the material 4 of the first role type is 1cm to 10cm, the zoom size of the material 5 is 3cm to 12cm, for example, the zoom size of the material 4 of the second role type is 1cm to 5cm, and the zoom size of the material 5 is 5cm to 20 cm.

Optionally, the second configuration instruction carries a second material identifier selected by the user, and a range value of the range parameter.

In one example, the first type of material includes material 1, material 2, and material 3, the material 2 is adjusted in a range of 1cm to 10cm, the size of the representative material 2 can be adjusted in a range of 1cm to 10cm, the second type of material includes material 4 and material 5, the first type of material is a special material for the character type to which the first virtual character belongs, and the material 1, the material 2, and the material 3 are respectively tail, hair style, and horns, the second type of material is a general material for all the character types, and the material 4 and the material 5 are respectively eyes and mouth. The user selects the material 4 on the configuration interface, inputs a zoom parameter of 5cm, and triggers a second configuration instruction, wherein the second configuration instruction carries an adjustment parameter of the user for the material 4, and because the adjustment parameter is located in a target parameter range corresponding to the material 4 in the target feature library, the user positions the eye in the basic body based on the second configuration instruction, and then zooms the length of the eye according to the second configuration instruction.

In one case, the target feature library comprises a first type of material and a target range parameter corresponding to the first type of material, after a first configuration instruction is received, a first sub-model corresponding to the selected first type of material is called, then the first sub-model is mounted on the basic body, a fourth configuration instruction is further received, the fourth configuration instruction carries an adjusting parameter of a user for the first sub-model, and when the adjusting parameter is located in a target parameter range corresponding to the first type of material in the target feature library, the first sub-model is adjusted according to the adjusting parameter.

In some other examples, in addition to configuring the zoom size, the zoom size may be configured for the type of character, the shape of the material may be selectable (e.g., a monster may select triangular and rectangular eyes, and a human may select only elliptical eyes), the angle and orientation of the material may be adjusted based on the reference position, the material may correspond to a sub-model selectable hanging point (e.g., a monster may have eyes hanging on the top and neck, and a human may have eyes hanging on the face), the filling color of the material may be selectable, and the like.

When the embodiment is applied to a face-pinching system, the corresponding feature library can be called for loading by matching the race, occupation and the like of the current role, and the user can only select the material configured with the first role image in the feature library to adjust the basic body (such as adding some organs, ornamentations and the like), so as to pinch the first role image desired by the user. Aiming at common and common organs of a role, such as eyes, a nose and other organs of the role, a code is configured for each race or occupation, the code corresponds to the adjustable range of a certain organ, and if the adjustable range of the eye size of a human is 2-10, and the adjustable range of the eye size of a demon is 0-20, the maximum eye size of the human can only reach 10, and the maximum eye size of the demon can reach 20. In the face pinching system, a plurality of sub-models such as character hairstyles are hung on a basic body, and a sub-model of hair is hung on the basic body for presenting the hairstyle, so that the structure of the basic body is not influenced when the hairstyle is adjusted.

In some embodiments, before searching the target feature library from the first material library according to the role type, the method further comprises: receiving a third configuration instruction, wherein the third configuration instruction is used for indicating the selected material library type; selecting a first material library from a plurality of types of material libraries based on a third configuration instruction, wherein each type of material library corresponds to one rendering style; the first material library is loaded locally.

In this embodiment, in the initial configuration stage, a material library preferred by a user may be selected from a plurality of material libraries each including a plurality of sets of feature libraries corresponding to a plurality of role types as the target material library. For example, the system comprises a low-mode material library and a high-mode material library (the low mode and the high mode can correspond to different rendering styles), each new role type is created in the game, the art production personnel can draw characteristic materials of the low-mode material library and the high-mode material library, when a user enters the game, the user selects the material library of the version desired by the user through checking, selects the characteristic library matched with the role type from the material library, and further picks out the desired first role image.

In one embodiment of this embodiment, invoking the basic body of the role model includes: acquiring gender attribute information of a first virtual role; if the gender attribute information indicates that the first virtual role is the first gender, calling a first basic body matched with the first gender; and if the gender attribute information indicates that the first virtual role is of the second gender, calling a second basic body matched with the second gender, wherein the role model comprises the first basic body and the second basic body.

The first sex and the second sex are respectively male and female, the character model comprises two general basic bodies, and a uniform basic body can be set for male, female and neutral.

Based on the above embodiment, after generating the first character image of the first virtual character, the method further includes:

s11, rendering and displaying a first role image of a first virtual role in a virtual scene, and adding a first rendering identifier in attribute information of the first virtual role, wherein the first rendering identifier is used for indicating a material library type corresponding to the first role image of the first virtual role;

s12, acquiring a second rendering identifier of a second virtual character in the virtual scene, wherein the second rendering identifier is used for indicating a material library type corresponding to a first character image of the second virtual character;

and S13, if the second rendering identifier is not consistent with the first rendering identifier, requesting a second character image of the second virtual character from the server, wherein the second character image is generated based on the first material library and corresponds to the first character image of the second virtual character, and displaying the received second character image of the second virtual character in the virtual scene.

The second character image of the second virtual character corresponds to the first character image of the second virtual character, and the second character image and the first character image can be generated by using materials in two material libraries in the same character type. For example, the first character image is generated using the feature library corresponding to the monster under the second material library, and the second character image is generated using the feature library corresponding to the monster under the first material library. The received second character image of the second virtual character is displayed in the virtual scene, so that the style of the virtual character rendered in the virtual scene is unified.

Fig. 4 is a schematic diagram of a first character image configured based on two feature libraries, which respectively correspond to two types of material libraries and a same organ, wherein the images configured by using the two material libraries have a certain visual difference, the first style is visually more realistic, and the second style is visually more quadratic.

In some examples, in order to reduce the storage amount, two sets of character images are not pre-stored locally, and when a uniform rendering style is required, if the second rendering identifier is inconsistent with the first rendering identifier, the first character image of the second virtual character is reconfigured by using the first material library, and the reconfigured first character image of the second virtual character (i.e., the second character image of the second virtual character) is displayed in the virtual scene.

In one example, reconfiguring the first persona representation of the second virtual persona using the first library of materials comprises: reading image configuration parameters of a first character image of a second virtual character; and generating a second character image of the second virtual character based on the image configuration parameters and the first material library.

Optionally, the avatar configuration parameters include: and configuring a material identifier of at least one material used by the first character image of the second virtual character and an adjusting parameter corresponding to the at least one material, wherein the material in each material library has a unique material identifier, and part or all of the materials in the first material library have corresponding materials in the second material library. Optionally, a corresponding relationship between the material in each target feature library in the first material library and the material in each target feature library in the second material library is established, and a mapping relationship between the target range parameter of the material in each target feature library in the first material library and the target range parameter of the material in each target feature library in the corresponding second material library. Generating a second character image of the second virtual character based on the image configuration parameters and the first material library, including: searching the materials in the first material library corresponding to the material identification according to the corresponding relation between the material identification and the materials in the image configuration parameters, mapping the adjusting parameters of each material in the image configuration parameters according to the mapping relation between the target range parameters so as to obtain the adjusting parameters corresponding to the materials in the first material library, and adjusting the role model basic body corresponding to the first material library according to the searched materials in the first material library and the corresponding adjusting parameters so as to obtain the second role image of the second virtual role. When the materials represented by the material identifiers in the image configuration parameters do not have corresponding materials in each target feature of the first material library, calling default materials corresponding to the material identifiers in the universal materials corresponding to the character model basic bodies according to the material identifiers, and adjusting the basic bodies of the character models by using the default parameters corresponding to the default materials. Through the mode, the second role image corresponding to the second virtual role under the first material library can be obtained according to the first role image of the second virtual role under the second material library, the two role images of the second virtual role are of the same role type, the consistency of virtual role expression in a virtual scene is realized, and when no corresponding material exists in the first material library, the second role image is generated by using the default material in the general material, so that the integrity of the generated second role image is ensured.

For example, character a uses a first material library configuration on user a's client, character a1, character B uses a second material library configuration on user B's client, character B1, in the game scene rendered and displayed on user a's client, in order to unify rendering style, character B1 needs to be replaced with character B2 unified with character a1 style, character B1 uses materials a2 and material B2 of the second material library, and corresponding adjustment parameters a2-2, B2-2, in the process of generating a new second character (B2), material a2 and material B2 are replaced with corresponding materials a1 and material B1 in the first material library (a2 and a1, B2 and B1 are all corresponding materials, for example, a2 and a1 are both noses), parameters a2-2 and B2-2 are mapped to parameters in the first material library a1 a1-1, b1-1, adjusting the character model basic body corresponding to the first material library according to the material a1, the material B1 and the corresponding adjusting parameters a1-1 and B1-1 to obtain a second character image B2, wherein the image A1 is also configured based on the material and the adjusting parameters of the first material library, so that the reconfigured B2 and A1 belong to the same rendering style, and the unification of the rendering styles is realized.

In some embodiments, after generating the first character image of the first virtual character, further comprising: selecting a second material library; determining image configuration parameters of the first character image, wherein the image configuration parameters are used for representing materials adopted by the first character image and adjustment parameters of corresponding materials; generating a second character image of the first virtual character based on the image configuration parameters and the second material library. The process of generating the second character image of the first virtual character based on the image configuration parameters and the second material library is similar to the process of generating the second character image of the second virtual character, and is not repeated herein.

Optionally, the basic body of the character model includes a low-model basic body and a high-model basic body, when the user selects to use the high-model basic body to generate the character image, the character type under the high-model basic body can be further selected, and the game client can search the target feature library corresponding to the character type in the first material library corresponding to the high-model basic body based on the selection of the user. After the user finishes pinching the face to generate the high-mode character image, the game client can generate the corresponding low-mode character image based on the high-mode character image.

In one example, a first character image of a first virtual character is configured by a first material library of a high-modulus basic body, a second character image of the first virtual character is configured by a second material library of a low-modulus basic body, after face pinching image configuration is completed based on the high-modulus basic body, a set of corresponding low-modulus second character images are generated according to high-modulus image configuration parameters, and hair styles, eyes and the like in the low-modulus second character images correspond to the high modulus; if the low mode does not support certain character configuration parameters for the high mode, default data is used and both the high mode character and the low mode character are stored on the server as well.

In some scenarios, in order to ensure uniformity of rendering styles on the same client, the game server needs to use the same material library to load virtual characters displayed on the same client, specifically which material library is adopted based on a material library adopted by a first virtual character selected by a user or used by the user, in one example, the game scene of the client a includes three virtual characters, namely a character a, a character B and a character C, wherein the character a is a user's own virtual character, namely a first virtual character, the character B is a virtual character used by teammates and local teammates, namely a second virtual character, the character a and the character B are character images configured by using the first material library, the character C is a character image configured by using the second material library, the game server reads a second characteristic material set in the second material library adopted by the game server in a configuration table of the character images by analyzing the character image of the character C, and replacing the first characteristic material set in the corresponding first material library, or directly acquiring a previously pre-stored role image configured by adopting the first material library by adopting the role C in the game server, and issuing corresponding role rendering data to the client A, thereby unifying the rendering style on the client A.

On a game terminal or a server, the system is provided with a material library of a low-mode face pinching system and a material library of a high-mode face pinching system, the material libraries respectively correspond to a first rendering identifier and a second rendering identifier, and the high-mode material library is redrawn based on the low-mode material library, is of two different styles of rendering styles and is suitable for different user preferences. Two kinds of face systems of holding between the fingers can coexist and freely switch, the player can select low mould to hold between the fingers face system or high mould to hold between the fingers the role image that oneself wanted, show in the recreation, the player also can select to show in the recreation scene through the configuration in advance and hold between the fingers face system or high mould to hold between the fingers one of face system, if select to show low mould to hold between the fingers face system, no matter be with the low mould or the high mould in the recreation scene hold between the fingers the role image that the face system held between the fingers, only load the characteristic image that shows the low mould and hold between the fingers the face system, in order to guarantee the unification of rendering style on every game terminal, reduce the memory pressure that two kinds of material storehouses of simultaneous loading brought simultaneously. The system loads feature libraries of low-mode face pinching and high-mode face pinching at the client, and because each feature of the feature libraries in the low-mode face pinching system and the high-mode face pinching system is mapped one by one, the high-mode features can be directly switched into corresponding low-mode features, and as for the features which cannot be in one-to-one correspondence, default feature materials or material parameters are adopted for adaptation. The method breaks through the limitation that different ethnic groups need to adopt different basic bodies, and realizes the uniformity, systematicness and normalization of the role model.
