Description

Technical Field

[0001] This application relates to the field of computers, and more specifically, to a method and apparatus for generating virtual facial expressions, a storage medium, and an electronic device. Background Technology

[0002] Currently, in the process of creating a large number of virtual expressions, artists usually draw them in advance and modify the eye mesh through skeletal deformation to achieve different virtual expressions, or they draw different complete virtual expression textures to achieve different effects.

[0003] If a skeletal deformation scheme is used, a higher polygon count and more skeletal control nodes are required to achieve the desired effect, which places higher demands on rendering performance. Furthermore, drawing different complete virtual facial expression textures requires adding a virtual facial expression texture for each virtual expression. If there are requirements such as changing the pupil color, the number of facial expression textures increases exponentially, resulting in excessively high art costs and wasted resources.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0054] S206, Based on the first display parameters, the first eye socket texture and the first eyeball texture are combined to form the first virtual expression of the target virtual object.

[0055] Optionally, in the embodiments of this application, the above-described method for generating virtual expressions can be applied to application scenarios that require the use of virtual expressions, including but not limited to game applications, as well as applications that require the use of virtual expressions, such as live streaming applications, video production applications, information interaction in instant messaging applications, and design applications for virtual characters or virtual animals.

[0056] For example, Figure 3 This is a schematic diagram of an optional virtual emoticon generation method according to an embodiment of this application, such as... Figure 3 As shown, the above-mentioned method for generating virtual expressions can be applied to the process of generating virtual expressions for game characters. A first eye socket image is selected from the first image set based on interactive operations, and a first eyeball image is selected from the second image set based on interactive operations. Then, based on the first display parameters, the first eye socket image and the first eyeball image are combined into the first virtual expression of the target virtual object.

[0057] Optionally, in this embodiment of the application, the first texture set and the second texture set are texture sets composed of textures pre-made by artists, wherein the textures in the first texture set represent the virtual eye sockets of the target virtual object, and the textures in the second texture set represent the virtual eyeballs of the target virtual object.

[0058] For example, Figure 4 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 4As shown, the first set of textures may include, but is not limited to, virtual eye sockets 402, 404, 406 and 408, and the second set of textures may include, but is not limited to, virtual eyeballs 410, 412, 414 and 416. It may include, but is not limited to, selecting virtual eye sockets 404 and virtual eyeballs 410 according to interactive operations, and combining the first eye socket texture and the first eyeball texture into the first virtual expression of the target virtual object according to the first display parameters.

[0060] Optionally, in this embodiment of the application, the above-mentioned acquisition of the first eye socket texture in the first texture set may include, but is not limited to, selecting the first eye socket texture from the first texture set according to the expression type of the virtual expression configured for the target virtual object in advance, and the above-mentioned acquisition of the first eyeball texture in the second texture set may include, but is not limited to, selecting the first eyeball texture from the second texture set according to the expression type of the virtual expression configured for the target virtual object in advance.

[0061] Optionally, in this embodiment of the application, the first display parameter may include, but is not limited to, the functional map corresponding to the first eye socket map. The functional map may include, but is not limited to, a four-channel map, such as an RGBA functional map. The RGB channels of the functional map store the eye socket range, the eye shadow range, and the highlight flicker range, respectively. The Alpha channel may store other related parameters of the virtual eyeball and the virtual eye socket, such as the shape of the eye socket.

[0062] It should be noted that the first display parameter mentioned above is a display parameter used to display the virtual eyeball in the virtual eye socket. For example, the position of the virtual eyeball displayed on the virtual eye socket, the range of the virtual eyeshadow when the virtual eyeball is displayed in the virtual eye socket, and the range of the highlight flashing points when the virtual eyeball is displayed in the virtual eye socket.

[0063] For example, Figure 5 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 5As shown, the first display parameter may include, but is not limited to, determining the corresponding functional texture based on the first eye socket texture selected from the first texture set. The functional texture includes at least three channels: RGB, where the R channel records the eye socket range of the first eye socket texture, the G channel records the eyeshadow range of the first eye socket texture, and the B channel records the range of the highlight flicker points corresponding to the first eye socket texture.

[0064] Optionally, in this embodiment of the application, the first virtual expression of the target virtual object, which is synthesized from the first eye socket texture and the first eyeball texture according to the first display parameters, may include, but is not limited to, drawing the virtual eyeball represented by the first eyeball texture in the eye socket area indicated by the first display parameters, drawing the eyeshadow of the virtual eyeball in the eyeshadow area indicated by the first display parameters, and drawing the highlight flashing point of the virtual eyeball in the highlight flashing point area indicated by the first display parameters.

[0065] For example, Figure 6 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 6 As shown, the process may include, but is not limited to, determining a first eye socket texture from a first texture set, determining a first display parameter corresponding to the first eye socket texture, determining a first eyeball texture from a second texture set, and combining the first eye socket texture and the first eyeball texture into a first virtual expression of the target virtual object based on the first display parameter.

[0066] This application embodiment employs a method of acquiring a first texture set and a second texture set. The first texture set includes pre-configured textures representing virtual eye sockets of a target virtual object, and the second texture set includes pre-configured textures representing virtual eyeballs of the target virtual object. The method involves acquiring a first eye socket texture from the first texture set, acquiring a first eyeball texture from the second texture set, and acquiring a first display parameter. The first display parameter is used to display the virtual eyeball represented by the first eyeball texture within the virtual eye socket represented by the first eye socket texture. Based on the first display parameter, the first eye socket texture and the first eyeball texture are combined to form a first virtual expression of the target virtual object. By creating the virtual eye socket and virtual eyeball separately and controlling the switching of the virtual eye socket using code, a highly customizable virtual expression function is achieved. This allows for the combination of different virtual eye socket and virtual eyeball effects, thereby reducing the cost of art production and lowering the cost of generating virtual expressions. Furthermore, this solves the technical problem of high virtual expression generation costs in related technologies.

[0067] Furthermore, by creating the virtual eye sockets and virtual eyeballs separately, and then controlling the switching of the virtual eye sockets through code, while using algorithms to process the virtual eyeballs including but not limited to color changes, scaling, and displacement, different combinations of virtual eye sockets and virtual eyeballs can be achieved, as well as the virtual eyeballs' perspective-following effect. This allows for the realization of almost all eye expression effects while reducing the cost of art production. Players can freely combine virtual eye sockets and virtual eyeballs, achieving a high degree of freedom in customizing player expressions.

[0068] As an alternative solution,

[0069] The method also includes: obtaining a target switching request when the current virtual expression of the target virtual object is a virtual expression obtained by compositing the second eye socket texture from the first texture set and the second eyeball texture from the second texture set;

[0070] Obtaining the first eye socket texture from the first texture set and the first eyeball texture from the second texture set includes: when the target switching request is used to request switching the virtual eyeball in the current virtual expression, using the second eye socket texture as the first eye socket texture and obtaining the selected first eyeball texture from the second texture set, wherein the first eyeball texture is different from the second eyeball texture.

[0071] Optionally, in the embodiments of this application, the target switching request may include, but is not limited to, a switching request generated by the user or the system. In other words, the user may perform an interactive operation to trigger the execution of the target switching request, or a corresponding time point may be pre-configured, and then the system may trigger the execution of the target switching request at the aforementioned time point.

[0072] Optionally, in this embodiment of the application, the above-mentioned target switching request for requesting to switch virtual eyeballs may include, but is not limited to, changing the above-mentioned second eyeball texture to the above-mentioned first eyeball texture, while keeping the second eye socket texture unchanged, so as to quickly generate virtual expressions that only switch virtual eyeballs.

[0073] Optionally, in this embodiment of the application, the above-mentioned second eyeball texture and the above-mentioned second eye socket texture are the current virtual expressions of the target virtual object. The above-mentioned target switching request can switch the current virtual expressions of the target virtual object. The difference between the above-mentioned second eyeball texture and the above-mentioned first eyeball texture may include, but is not limited to, differences in the shape, size, color, etc. of the virtual eyeball.

[0074] For example, Figure 7 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 7 As shown, the steps may include, but are not limited to, the following:

[0075] S1, Obtain the target switching request and perform interactive operations on "Switch Eyeball";

[0076] S2, Select the first eyeball texture from the second texture set;

[0077] S3, use the second eye socket texture as the first eye socket texture, and obtain the first eyeball texture selected in the second texture set. Combine the second eye socket texture and the first eyeball texture to obtain the virtual expression.

[0078] The above is merely an example, and the embodiments in this application do not impose any specific limitations.

[0079] In this embodiment, when the current virtual expression of the target virtual object is a virtual expression synthesized from the second eye socket texture in the first texture set and the second eyeball texture in the second texture set, a target switching request is obtained. When the target switching request requests to switch the virtual eyeball in the current virtual expression, the second eye socket texture is used as the first eye socket texture, and the first eyeball texture selected in the second texture set is obtained. The first eyeball texture and the second eyeball texture are made differently. By creating the virtual eye socket and the virtual eyeball separately, and using code to control the switching of the virtual eyeball, a new virtual expression can be generated, realizing a highly customizable virtual expression function. This achieves the goal of allowing the combination of virtual eye socket and different virtual eyeball effects to realize a highly customizable virtual expression function, thereby reducing the cost of art production and the technical effect of reducing the generation cost of virtual expressions. In turn, it solves the technical problem of high generation cost of virtual expressions in related technologies.

[0080] As an alternative solution,

[0081] The above method also includes: obtaining a target switching request when the current virtual expression of the target virtual object is a virtual expression obtained by compositing the second eye socket texture in the first texture set and the second eyeball texture in the second texture set;

[0082] Obtaining the first eye socket texture from the first texture set and the first eyeball texture from the second texture set includes: when the target switching request is used to request switching the virtual eye socket in the current virtual expression, obtaining the first eye socket texture selected in the first texture set and using the second eyeball texture as the first eyeball texture, wherein the first eye socket texture and the second eye socket texture are different.

[0083] Optionally, in the embodiments of this application, the target switching request may include, but is not limited to, a switching request generated by the user or the system. In other words, the user may perform an interactive operation to trigger the execution of the target switching request, or a corresponding time point may be pre-configured, and then the system may trigger the execution of the target switching request at the aforementioned time point.

[0084] Optionally, in this embodiment of the application, the above-mentioned target switching request for requesting to switch the virtual eye socket may include, but is not limited to, changing the above-mentioned second eye socket texture to the above-mentioned first eye socket texture, while keeping the second eyeball texture unchanged, so as to quickly generate a virtual expression that only switches the virtual eye socket.

[0085] Optionally, in this embodiment of the application, the second eyeball texture and the second eye socket texture are the current virtual expressions of the target virtual object. The target switching request can switch the current virtual expressions of the target virtual object. The second eye socket texture may differ from the first eye socket texture in terms of shape, size, color, etc., and may also include, but is not limited to, adjusting the display parameters corresponding to the second eye socket texture to the display parameters corresponding to the first eye socket texture.

[0086] For example, Figure 8 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 8 As shown, the steps may include, but are not limited to, the following:

[0087] S1, Obtain the target switching request and perform an interactive operation on "Switch eye socket";

[0088] S2, Select the first eye socket texture from the first texture set;

[0089] S3, use the second eyeball texture as the first eyeball texture, and obtain the first eye socket texture selected in the first texture set. Combine the second eyeball texture and the first eye socket texture to obtain the virtual expression.

[0090] The above is merely an example, and the embodiments in this application do not impose any specific limitations.

[0091] In this embodiment, when the current virtual expression of the target virtual object is a virtual expression synthesized by combining the second eye socket texture from the first texture set and the second eyeball texture from the second texture set, a target switching request is obtained, the first eye socket texture from the first texture set is obtained, and the first eyeball texture from the second texture set is obtained. This includes: when the target switching request is used to request switching the virtual eye socket in the current virtual expression, the first eye socket texture selected in the first texture set is obtained, and the second eyeball texture is used as the first eyeball texture. The first eye socket texture and the second eye socket texture are created differently. By creating the virtual eye socket and the virtual eyeball separately, and using code to control only the switching of the virtual eye socket, a new virtual expression can be generated. This achieves a high degree of freedom in customizing virtual expressions, allowing different virtual eye socket effects and virtual eyeballs to be combined to achieve a high degree of freedom in customizing virtual expressions. This reduces the cost of art production and lowers the cost of generating virtual expressions, thus solving the technical problem of high generation costs for virtual expressions in related technologies.

[0092] As an alternative solution,

[0093] The above method also includes: obtaining a target switching request when the current virtual expression of the target virtual object is a virtual expression obtained by compositing the second eye socket texture in the first texture set and the second eyeball texture in the second texture set;

[0094] Obtaining the first eye socket texture from the first texture set and the first eyeball texture from the second texture set includes: when the target switching request is used to request switching the virtual eye socket and virtual eyeball in the current virtual expression, obtaining the first eye socket texture selected in the first texture set and obtaining the first eyeball texture selected in the second texture set, wherein the first eye socket texture is different from the second eye socket texture and the first eyeball texture is different from the second eyeball texture.

[0095] Optionally, in the embodiments of this application, the target switching request may include, but is not limited to, a switching request generated by the user or the system. In other words, the user may perform an interactive operation to trigger the execution of the target switching request, or a corresponding time point may be pre-configured, and then the system may trigger the execution of the target switching request at the aforementioned time point.

[0096] Optionally, in this embodiment of the application, the target switching request is used to request the simultaneous switching of the virtual eye socket and the virtual eyeball. This may include, but is not limited to, changing the second eye socket texture to the first eye socket texture and changing the second eyeball texture to the first eyeball texture to achieve rapid generation of a new virtual expression, and the new virtual expression simultaneously replaces the virtual eye socket and the virtual eyeball.

[0097] Optionally, in this embodiment, the second eyeball texture and the second eye socket texture are the current virtual expressions of the target virtual object. The target switching request can switch the current virtual expressions of the target virtual object. The second eye socket texture may differ from the first eye socket texture in, but is not limited to, the shape, size, and color of the virtual eye socket. It may also include, but is not limited to, adjusting the display parameters corresponding to the second eye socket texture to the display parameters corresponding to the first eye socket texture. The second eyeball texture may differ from the first eyeball texture in, but is not limited to, the shape, size, and color of the virtual eyeball.

[0098] For example, Figure 9 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 9 As shown, the steps may include, but are not limited to, the following:

[0099] S1, Obtain the target switching request and perform an interactive operation on "Switch Emoji";

[0100] S2, Select the first eye socket texture from the first texture set, and select the first eyeball texture from the second texture set;

[0101] S3: Obtain the first eye socket texture selected in the first texture set, and obtain the first eyeball texture selected in the second texture set. Combine the first eye socket texture and the first eyeball texture to obtain a virtual expression.

[0102] The above is merely an example, and the embodiments in this application do not impose any specific limitations.

[0103] In this embodiment, when the current virtual expression of the target virtual object is a virtual expression synthesized from the second eye socket texture in the first texture set and the second eyeball texture in the second texture set, a target switching request is obtained. When the target switching request requests to switch the virtual eye socket and virtual eyeball in the current virtual expression, the first eye socket texture selected in the first texture set and the first eyeball texture selected in the second texture set are obtained. The first eye socket texture is different from the second eye socket texture, and the first eyeball texture is different from the second eyeball texture. By creating the virtual eye socket and virtual eyeball separately and controlling the switching of the virtual eye socket and virtual eyeball simultaneously using code, a new virtual expression can be generated. This achieves a high degree of freedom in customizing virtual expressions, allowing different virtual eye socket effects and different virtual eyeball effects to be combined to achieve a high degree of freedom in customizing virtual expressions. This reduces the cost of art production and lowers the cost of generating virtual expressions, thus solving the technical problem of high generation cost of virtual expressions in related technologies.

[0104] As an alternative solution,

[0105] The above method further includes: when the current virtual expression of the target virtual object is a virtual expression obtained by compositing the second eye socket texture in the first texture set and the second eyeball texture in the second texture set according to the second display parameters, obtaining a target switching request, wherein the second display parameters are display parameters used to display the virtual eyeball represented by the second eyeball texture in the virtual eye socket represented by the second eye socket texture;

[0106] Obtain the first eye socket texture from the first texture set, obtain the first eyeball texture from the second texture set, and obtain the first display parameters, including: when the target switching request is used to request switching the display parameters of the virtual eyeball in the current virtual expression, use the second eye socket texture as the first eye socket texture, use the second eyeball texture as the first eyeball texture, and obtain the first display parameters, wherein the first display parameters are different from the second display parameters.

[0107] Optionally, in the embodiments of this application, the target switching request may include, but is not limited to, a switching request generated by the user or the system. In other words, the user may perform an interactive operation to trigger the execution of the target switching request, or a corresponding time point may be pre-configured, and then the system may trigger the execution of the target switching request at the aforementioned time point.

[0108] Optionally, in this embodiment of the application, the above-mentioned target switching request is used to request the switching of the second display parameter of the virtual eye socket to the first display parameter, so as to realize the rapid adjustment of the display parameters of the virtual eyeball in the virtual eye socket.

[0109] It should be noted that the above display parameters can be adjusted using the material ball.

[0110] Optionally, in this embodiment of the application, the above-mentioned second eyeball texture and the above-mentioned second eye socket texture are the current virtual expressions of the target virtual object. The above-mentioned target switching request can switch the current virtual expressions of the target virtual object. The difference between the above-mentioned first display parameters and second display parameters may include, but is not limited to, the different sizes of the eye shadow range of the virtual eyeball in the virtual eye socket, and at least one of the different color-changing information, scaling information and position information of the virtual eyeball.

[0111] For example, Figure 10 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 10 As shown, the steps may include, but are not limited to, the following:

[0112] S1, obtain the target switching request and perform the interactive operation on "adjust highlight point";

[0113] S2, obtain the first display parameter from the material sphere;

[0114] S3, Based on the first display parameters, the first eye socket texture and the first eyeball texture are combined to obtain a virtual expression.

[0115] The above is merely an example, and the embodiments in this application do not impose any specific limitations.

[0116] In this embodiment, when the current virtual expression of the target virtual object is a virtual expression synthesized by combining the second eye socket image from the first image set and the second eyeball image from the second image set according to the second display parameters, a target switching request is obtained. The second display parameters are used to display the virtual eyeball represented by the second eyeball image within the virtual eye socket represented by the second eye socket image. When the target switching request requests a change in the display parameters of the virtual eyeball in the current virtual expression, the second eye socket image is used as the first eye socket image, the second eyeball image is used as the first eyeball image, and the first display parameters are obtained. The method involves creating virtual eye sockets and virtual eyeballs separately and configuring corresponding material spheres. By modifying the material spheres using code, the display parameters of the virtual eyeballs within the virtual eye sockets can be changed, generating new virtual expressions. This achieves a high degree of freedom in customizing virtual expressions, allowing virtual eye sockets and virtual eyeballs to be combined with different display parameters. This reduces the cost of art production and lowers the cost of generating virtual expressions, thus solving the technical problem of high virtual expression generation costs in related technologies.

[0117] In addition, the size and direction of the virtual eyeballs can be configured according to the player's preferences, including but not limited to. For example, the virtual eyeballs can be shrunk to express shock, or the virtual eyeballs can be tilted upwards when in normal state to show a shy expression in conjunction with a custom blush effect, thus achieving a high degree of freedom in eye expression effects.

[0118] Meanwhile, when needing to create dazzling virtual eye effects in cartoon style, the HSV color-changing scheme can be used, including but not limited to, to ensure that the color gradient effect is preserved during the color-changing process. In addition to freely combining eye socket and eyeball effects, players can achieve any facial expression without having to draw a massive number of facial textures. For players, the process of creating virtual expressions is simple: just replace the textures of the virtual eye socket and virtual eyeball. By adjusting the parameters appropriately, players can obtain custom expressions that meet their actual needs, optimizing the user experience and improving the efficiency of creating complex virtual expressions.

[0119] As an optional approach, based on the first display parameters, the first eye socket texture and the first eyeball texture are combined to form the first virtual expression of the target virtual object, including:

[0120] If the first display parameters include the orbital range of the virtual eye socket represented by the first eye socket texture, the virtual eyeball represented by the first eyeball texture is added to the middle of the orbital range to obtain the first expression texture to be used;

[0121] Generate the first virtual emoticon based on the first emoticon image.

[0122] Optionally, in the embodiments of this application, the expression texture may include, but is not limited to, dividing the expression texture into eye socket texture, eyeball texture and function texture. By designing two sets of UVs, one set is used to flatten the face of the target virtual object, and the other set is used to process the eye area. Finally, the eye area effect is blended with the facial effect.

[0123] For example, Figure 11 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 11 As shown, the steps may include, but are not limited to, the following:

[0124] S1, flatten the face of the target virtual object, such as UV1. At this time, only the parts of the target virtual object's face other than the eye expression are processed.

[0125] S2, flatten the eye area of ​​the target virtual object, such as UV2, and add the first eye socket map and the first eyeball map to UV2;

[0126] S3, based on the first display parameters, add a virtual eyeball to the middle of the eye socket area to achieve the processing of the eye area effect.

[0127] The above is merely an example, and the embodiments in this application do not impose any specific limitations.

[0128] As an optional approach, a first virtual emoticon is generated based on the first emoticon image, including one of the following:

[0129] If the first display parameters also include the eyeshadow range of the virtual eye socket represented by the first eye socket texture, the eyeshadow of the virtual eyeball represented by the first eyeball texture is added to the middle of the eyeshadow range in the first expression texture to obtain the second expression texture; and the first virtual expression is generated based on the second expression texture.

[0130] If the first display parameters also include the blinking position coordinates of the virtual eye represented by the first eye map, the blinking point of the virtual eye represented by the first eye map is added to the blinking position coordinates in the first expression map to obtain the third expression map; and the first virtual expression is generated based on the third expression map.

[0131] If the first display parameters also include the eyeshadow range of the virtual eye socket represented by the first eye socket texture and the blinking position coordinates of the virtual eyeball represented by the first eyeball texture, the eyeshadow of the virtual eyeball represented by the first eyeball texture is added to the middle of the eyeshadow range in the first expression texture, and the blinking point of the virtual eyeball represented by the first eyeball texture is added to the blinking position coordinates to obtain the fourth expression texture; the first virtual expression is generated based on the fourth expression texture.

[0132] Optionally, in this embodiment, the aforementioned eyeshadow range represents the shadow range of the upper eyelid of the virtual eyeball, and the aforementioned flashing position coordinates represent the display position coordinates of the highlight of the virtual eyeball.

[0133] Optionally, in this embodiment, the second, third, and fourth emoticon images are all first virtual emoticons with modified display parameters.

[0134] As an optional approach, after generating the first virtual emoticon based on the first emoticon image, the method further includes:

[0135] Upon receiving a color update instruction, the color of the virtual eye represented by the first eyeball texture is modified according to the color update instruction in order to update the first virtual expression;

[0136] Upon receiving a scaling update instruction, the virtual eyeball represented by the first eyeball texture is scaled according to the scaling update instruction in order to update the first virtual expression;

[0137] Upon receiving a location update command, the display position of the virtual eyeball represented by the first eyeball texture inside the virtual eye socket is modified according to the location update command in order to update the first virtual expression.

[0138] Optionally, in the embodiments of this application, the above-mentioned method of modifying the first eyeball texture according to the color update instruction, scaling update instruction and position update instruction may include, but is not limited to, modifying only the left eye or the right eye in the first eyeball texture, and then using a UV folding scheme to deform the other side accordingly.

[0139] Optionally, in the embodiments of this application, the above-mentioned color update instruction, scaling update instruction and position update instruction are all adjustment instructions executed on the eyeball by the shader, and the relevant parameters of the material ball are modified by the algorithm to update the first virtual expression.

[0140] As an optional approach, obtaining the first texture set and the second texture set includes:

[0141] The various textures to be synthesized virtual expressions are classified to obtain multiple texture sets representing different expression types. These multiple texture sets are stored in a database according to different expression types.

[0142] In response to the expression type selection operation, the first and second image sets are obtained from multiple image sets respectively.

[0143] Optionally, in this embodiment of the application, each texture of the virtual emoticon to be synthesized is designed by an art designer, and the emoticon type corresponding to the emoticon ID is predefined, for example, 0: normal, 1: closed eyes, 2: smiling, etc. During production, the texture names are processed according to the previously defined specifications so that when generating emoticons later, the texture of the corresponding emoticon type can be selected directly by adjusting the emoticon ID.

[0144] As an alternative solution,

[0145] Obtaining the first eye socket texture from the first texture set includes: in response to an expression type selection operation, determining the first loading path of the first eye socket texture; and determining the first eye socket texture from the first texture set based on the first loading path.

[0146] Obtaining the first eyeball image from the second image set includes: in response to an expression type selection operation, determining a second loading path for the first eyeball image; and determining the first eyeball image from the second image set based on the second loading path.

[0147] Optionally, in this embodiment, the first loading path and the second loading path can be stored in a database configuration file, and can be stored in a key-value format, for example, the key is the emoji ID and the value is the loading path of the emoji.

[0148] As an alternative approach, the method also includes:

[0149] Obtain the object type of the virtual object to be configured;

[0150] If the object type indicates that the virtual object to be configured is controlled by the target account, the first virtual object is configured to the virtual object to be configured.

[0151] When the virtual object whose object type indicates that the virtual emoticon to be configured is controlled by the server, the preset virtual emoticon is configured to the virtual object of the virtual emoticon to be configured.

[0152] Optionally, in this embodiment of the application, the above-mentioned object types may include, but are not limited to, virtual objects controlled by the user's login target account, such as game protagonists, and virtual objects automatically controlled by the server according to preset rules, such as NPCs.

[0153] It should be noted that when the virtual object to be configured is a virtual object controlled by the target account, the first virtual emoticon will be configured for that virtual object. When the virtual object to be configured is a virtual object controlled by the server, the pre-generated preset virtual emoticon will be configured for that virtual object.

[0154] The following specific examples will further explain this application:

[0155] This application provides a solution for highly customizable eye expressions in game characters, and optimizes the game production process. The solution is as follows: the eye texture is split into three parts: an eye texture without the pupil (corresponding to the aforementioned eyeball), a functional texture of the pupil area, and a separate pupil texture. These are integrated into a material sphere using an algorithm, and the changes in expression and pupil are controlled by the material sphere parameters.

[0156] By creating the eye sockets and pupils separately, controlling the switching of eye sockets through code, and using shader algorithms to process the pupils by changing their color, scaling, and displacement, different combinations of eye socket and pupil effects and eyeball perspective following effects can be achieved. This allows for the creation of almost all cartoon eye expression effects while reducing the cost of art production, reducing the package size, and enabling highly customizable player expressions.

[0157] In addition, to simplify the workflow and reduce the performance overhead of the game, a solution for non-highly customizable NPC expressions is also provided, which uses preset image sets of expressions and controls the generation with shader switches.

[0158] Specifically, this includes, but is not limited to, the following:

[0159] Model Design:

[0160] Two sets of UV filters need to be designed: one to flatten the face and the other to treat the eye area. Finally, the effect of the eye area will be blended with the effect of the face.

[0161] Eye socket texture design (corresponding to the aforementioned first eye socket texture):

[0162] The eye socket texture is designed by the art team and can have some color gradient tendencies. However, due to the need to match various skins and for performance and game requirements, the eye socket texture cannot have too strong a color tendency. In order to make the transition natural, the base color of the eye socket needs to be the color of the standard skin.

[0163] Pupil texture (corresponding to the aforementioned first eyeball texture) design:

[0164] To achieve the vibrant pupil effect characteristic of cartoons, the HSV color-changing scheme can be used, among other things, to ensure that the color gradient effect is preserved during the color-changing process.

[0165] When drawing pupils, artists need to design them based on standard pupil size and position to ensure that deformation parameters can be reused in the game.

[0166] When designing the artwork, it is necessary to ensure that the center point of the pupil is consistent with the reference pupil coordinates. The reference coordinates for scaling and displacement of the pupil in the shader are the center point of the left pupil. The pupil is deformed accordingly using a UV folding scheme.

[0167] Functional texture design:

[0168] The three channels of the functional texture store the eye socket area, eyeshadow area, and highlight flicker point area, respectively. The alpha channel has no function yet and is reserved.

[0169] For example, Figure 12 This is a schematic diagram of another optional method for generating virtual emoticons according to an embodiment of this application, such as... Figure 12 As shown, the steps may include, but are not limited to, the following:

[0170] The first step is to determine whether the virtual emoticon to be generated is the main character's emoticon. If not, switch to the conventional solution to reduce rendering pressure.

[0171] The second step is to determine whether the eye socket texture needs to be switched. If it needs to be switched, the database configuration file is read to obtain the corresponding eye socket texture and the corresponding function texture loading path. After loading, the original eye socket texture and the corresponding function texture are replaced.

[0172] The third step is to determine whether to switch the pupil texture. If switching is required, the database configuration file is read to obtain the corresponding eye socket texture loading path. After loading, the original pupil texture is replaced.

[0173] The fourth step is to determine whether the pupil transformation data has changed. The data comes from the initial configuration information of each pupil stored on the server and the parameters manually adjusted by the player. If it is determined that the pupil's color change information, scaling information, and position information have been updated, then the pupil-related parameters on the material ball are modified.

[0174] All required emoticon paths are configured through a database table, which can be added without limit. The emoticon ID and corresponding emoticon type are predefined, such as 0: normal, 1: closed eyes, 2: smiling, etc. When creating and configuring the table, the emoticon naming is handled according to the previously defined specifications.

[0175] In this embodiment, since the face and expression effects are blended using a single material sphere, no additional semi-transparent layer is needed to process the expression, reducing overdraw overhead. Assuming the expression transformation variables include switching eyes (x), switching pupils (y), changing pupil color (z), pupil scaling (w), and displacement (t), a conventional atlas solution would require creating x... y z w With t types of textures, the number of textures increases exponentially for complex requirements. However, the embodiment of this application only requires creating x types of textures. 2 (eye socket and function maps) + y types of maps greatly improve the workload for artists and reduce the size of the package.

[0176] In addition to freely customizing the eye socket and eyeball effects, players can also configure the size of the eyeballs and the direction of observation according to their preferences. For example, to express shock, the eyeballs can be shrunk, or the eyeballs can be tilted upwards when in a normal state, and a shy expression can be expressed by combining them with a custom blush effect.

[0177] In theory, this method can achieve any facial expression effect without drawing a huge number of facial expression textures, providing a simplified production process for cartoon animation.
