The block diagrams depicted in the figures are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.
FIG. 1 illustrates a schematic diagram of an exemplary system architecture for a method of character model processing to which embodiments of the present disclosure may be applied.
As shown in fig. 1, system architecture 1000 may include one or more of terminal devices 1001, 1002, 1003, a network 1004, and a server 1005. The network 1004 serves as a medium for providing a communication link between the terminal apparatuses 1001, 1002, 1003 and the server 1005. The network 1004 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation. For example, the server 1005 may be a server cluster formed by a plurality of servers.
A user can interact with a server 1005 via a network 1004 using terminal apparatuses 1001, 1002, 1003 to receive or transmit messages or the like. The terminal devices 1001, 1002, 1003 may be various electronic devices having a display screen including, but not limited to, smartphones, tablet computers, portable computers, desktop computers, and the like. In addition, the server 1005 may be a server providing various services.
In one embodiment, the execution subject of the method for processing a character model of the present disclosure may be a server 1005, and the server 1005 may acquire a plurality of first material ball files and animation data corresponding to the character model sent by the terminal devices 1001, 1002, 1003, merge the plurality of first material ball files to obtain one or more second material ball files, bake the animation data into a map to obtain a map file with animation data, generate a blueprint including a plurality of action nodes according to the map file, and render the character model according to the second material ball files, the map file, and the blueprint. In addition, the method of character model processing of the present disclosure may be performed by the terminal apparatuses 1001, 1002, 1003, etc. to implement a process of rendering a character model according to the second material ball file, the map file, and the blueprint.
Further, the implementation of the method of character model processing of the present disclosure may also be implemented by the terminal devices 1001, 1002, 1003 and the server 1005 in common. For example, the terminal device 1001, 1002, 1003 may acquire a plurality of first material ball files and animation data corresponding to the character model, merge the plurality of first material ball files to obtain one or more second material ball files, bake the animation data into a map to obtain a map file with animation data, generate a blueprint including a plurality of action nodes according to the map file, and send the second material ball files, the map file and the blueprint to the server 1005, so that the server 1005 may render the character model according to the second material ball files, the map file and the blueprint.
With the rapid development of software and hardware, more and more game engine tools have been developed. For example, unreal Engine (ghost engine 4, ue 4) may provide various tools for game designers to write games, which aims to enable the game designers to easily and quickly make game programs, to realize quick development, and to enable the game engines to call resources in order of the game design requirements and to control the running of the game.
In some games, character models are required to be set, and when the character models trigger certain preset conditions, corresponding actions are triggered. For example, in some life simulation games, multiple identical or similar passer-by characters may be set in the game scene, and when a player-controlled character collides with a passer-by character, the passer-by character will avoid the player-controlled character; or in some instant strategic games (Real-TIME STRATEGY GAME, RTS), an opponent soldier character may be set within the game scene that will attack the player-controlled soldier character as the player-controlled soldier approaches the opponent soldier character. In the UE4, an AI system is provided for game designers to handle the actions of character models of the type described above. A character model can be built, a plurality of material balls are rendered on the model, and then the CPU controls the character model, so that the character model executes corresponding actions.
However, since the character model has a plurality of material balls, if the number of character models needs to be increased, the number of the character models is increased by DRAW CALLS, so that the rendering speed is reduced, and the game frame rate is reduced rapidly; the CPU processes the animation data of the character model, and the pressure on the CPU is smaller when the number of the character models is smaller, but the operation pressure of the CPU is continuously increased along with the increase of the number of the character models, and the reduction of the game frame rate is also caused, so that the game running performance is influenced; in addition, as the number of character models increases, the interaction of actions between character models increases more and more frequently, further increasing the operation pressure of the CPU, resulting in a decrease in the game frame rate, and thus in a decrease in the game performance, resulting in discontent players.
According to the method for processing the character model provided in the present exemplary embodiment, a character model to be processed, a plurality of first material ball files and animation data corresponding to the character model may be obtained, the plurality of first material ball files are combined to obtain one or more second material ball files, the animation data are baked into a map to obtain a map file with animation data, a blueprint including a plurality of action nodes is generated according to the map file, and the character model is rendered according to the second material ball files, the map file and the blueprint. As shown in FIG. 2, the method of character model processing can include the steps of:
Step S210, acquiring a character model to be processed, and a plurality of first material ball files and animation data corresponding to the character model;
Step S220, combining the plurality of first material ball files to obtain one or more second material ball files;
step S230, baking the animation data into the map to obtain a map file with the animation data;
Step S240, generating a blueprint comprising a plurality of action nodes according to the mapping file, wherein the action nodes are used for indicating the positions of actions in the mapping file;
And step S250, rendering the character model according to the second material ball file, the map file and the blueprint.
According to the embodiment of the disclosure, the material ball files corresponding to the character model can be combined, the animation data are baked into the map file, and the character model is rendered through the combined material ball files, the map file and the blueprint. On one hand, the number of material balls of the character model can be reduced, the number of DRAW CALLS is reduced, the rendering speed is improved, and the game frame rate is improved; on the other hand, the animation data is baked into the map, and a plurality of actions of the character are realized through the animation map, so that the operation pressure of the CPU can be reduced, and the game performance can be improved.
Next, steps S210 to S250 of the character model processing in the present exemplary embodiment will be described in more detail with reference to the drawings and embodiments.
Step S210, acquiring a character model to be processed, and a plurality of first material ball files and animation data corresponding to the character model;
In one example embodiment of the present disclosure, the character model may include game characters in various games, such as TPS (third person perspective shooting), FPS (first person perspective shooting), RPG (role playing game), ACT (action game), SLG (strategy class game), FTG (fighting game), SPG (sports game class game), RCG (racing game), AVG (adventure game), RTS (instant strategy game), etc., and the character model processing scheme of the present disclosure may be applied as long as the scene relates to the character model. The character model may also include characters in an interactive application image application, and the like. Note that the present disclosure is not limited to the application scenario of the character model.
In one example embodiment of the present disclosure, a character model may include a main character, a match character, an enemy, a unit object in a game, a plurality of groups of objects having independent action elements, and the like, and a presentation form of the character model may include a human form, an animal form, an object form, and the like, and the character model may further include character models in which some characters have poor sense of existence, and which are embodied in a device form (e.g., a machine in a machine-class game, a tank in a tank-class game, an aircraft in an aviation-class game, and the like). The specific form of the color model is not particularly limited in the present disclosure.
In one example embodiment of the present disclosure, a character model may be created in a model creation tool. For example, a character model may be created in a Zbrush, maya, 3DMax, or the like tool and a material sphere rendered for the character model. Specifically, when rendering a texture ball for a character model, the texture ball rendering tool may be used. For example, an object to be rendered may be selected in a texture editor, and then a ball of the texture to be rendered may be selected to complete rendering. Furthermore, the material balls in the material ball rendering tool can be used, the material balls manufactured by other authors can be downloaded into the material ball rendering tool, or the material balls can be manufactured and used by themselves.
In one example embodiment of the present disclosure, when rendering a character model, the character model may be obtained after rendering a plurality of material balls in the character model due to different characteristics of various locations of the character model, and thus the character model has a plurality of first material ball files. For example, for a certain character model, the material balls may include a diffusion type material ball, a reflection type material ball, an opaque type material ball, and a concave-convex type material ball, and each type material ball further includes a plurality of material balls with different patterns, so that a plurality of first material ball files corresponding to the character model may be obtained.
In one example embodiment of the present disclosure, animation data corresponding to a character model may be acquired. Specifically, the animation data can be used to drive the character model to perform corresponding actions, and after the character model is created, the animation data corresponding to the character model can be created through an animation data creation tool.
For example, animation data corresponding to a character model can be produced through 3Dmax, a skeleton system corresponding to the character model is created according to the character model, binding between the skeleton system corresponding to the character model and the character model is performed, influence weight values of each skeleton in the skeleton system on corresponding parts of the character model are adjusted, so that the skeleton system corresponding to the character model is completely matched with the character model, action data of the corresponding skeleton are adjusted on key frames of each time axis, and then all actions of the character model are recorded through all the key frames on the time axis, so that the animation data corresponding to the character model is obtained. The animation data corresponding to the character model may be stored in a memory or a server of the terminal device, and may be acquired in the memory or the server when the animation data corresponding to the character model needs to be used. The method for generating the animation data corresponding to the character model is not particularly limited in the present disclosure.
Step S220, combining the plurality of first material ball files to obtain one or more second material ball files;
In an example embodiment of the present disclosure, a plurality of first material ball files may be combined to obtain one or more second material ball files. Specifically, in the process of rendering the character model, a draw call is called once per rendering, and as the number of first material ball files corresponding to the character model increases, the number of draw calls also increases, so that a plurality of first material ball files can be combined to obtain one or more second material ball files. When the combination is carried out, the material balls can be combined according to the material ball attributes of the material balls. For example, the first material ball files may be combined according to the style of the material ball, for example, the first material ball files of the same style may be combined together, the material ball may be combined according to the type of the material ball, and the material ball may be combined according to the processing mode of the material ball. For example, the material balls can render the character model in a NORMAL BUMP mode, or render the character model in a DirectX loader mode, and the material balls adopting a unified rendering mode can be combined together, so that the rendering of the material balls of the character model is facilitated, and the calculation pressure of the processor is reduced. The inventor of the application discovers that for 192 character models, 7700 times of draw calls are needed before the material ball files of the character models are not combined, and only 1000 times of draw calls are needed after the material ball files are combined, so that the game frame rate and the game stability are greatly improved. Note that, the method of merging the first material ball files is not particularly limited in this disclosure.
In an example embodiment of the present disclosure, a plurality of first material ball files may be combined to obtain one or more second material ball files. Specifically, the number of the second material ball files may be one or more. For example, the first material ball files may be merged into one or more second material ball files according to the type of the material ball files, if the plurality of first material ball files belong to the same material ball type, only one merged material ball file exists, and if the plurality of first material ball files include two material ball types, two merged material ball files exist; or the standard value of the number of the second material ball files can be set, so that the number of the combined second material ball files is a specific value, for example, a plurality of first material ball files can be combined according to the combination standard, if the number of the current material ball files is equal to the standard value of the number, the combination of the first material ball files is stopped, and all the current material ball files are used as the second material ball files. Note that, the number of the second material ball files is not particularly limited in this disclosure.
In an example embodiment of the present disclosure, the plurality of first material ball files may be combined according to the number of the plurality of first material ball files to obtain one or more second material ball files. For example, when the number of the first material ball files is large, a plurality of first material ball files may be combined; or when the number of the material ball files of a certain type in the plurality of first material ball files is large, the plurality of first material ball files can be combined. Note that, the specific manner of merging the plurality of first material ball files according to the number of the plurality of first material ball files is not particularly limited in the present disclosure.
In an example embodiment of the present disclosure, when the number of the plurality of first material ball files is greater than or equal to a first preset value, the plurality of first material ball files may be combined to obtain one or more second material ball files. Specifically, the first preset value may indicate that when the number of first material ball files corresponding to the character model is greater than the first preset value, the pressure is greater when rendering the character model. Therefore, when the number of the first material ball files is greater than or equal to the first preset value, the plurality of first material ball files can be combined. The first preset value can be adjusted according to the service scene, and is stored in the terminal equipment or the server, and when the number of the first material ball files is required to be compared with the first preset value, the first preset value is called from the terminal equipment or the server. It should be noted that, the specific numerical value of the first preset value is not particularly limited in this disclosure.
In an example embodiment of the present disclosure, the plurality of first material ball files may be combined according to the material ball attributes of the plurality of first material ball files to obtain one or more second material ball files.
Specifically, the ball properties corresponding to the plurality of first ball files may be acquired, and after the plurality of first ball files corresponding to the character model are acquired, the ball properties corresponding to the plurality of first ball files may be acquired. Specifically, the material ball attribute may include general material attributes such as color, material ball transparency, environmental color, self-luminescence, etc.; special effects such as hidden sources, glow intensity, etc. may also be included; high light coloration such as eccentricity, high light diffusion, reflectivity, etc. may also be included; ray tracing may also be included. Such as refractive index, refractive confinement, light absorptivity, etc. Note that, the material ball properties are not particularly limited in this disclosure. When the character model is rendered, different material balls can be rendered at different positions of the character model, and material ball attributes corresponding to a plurality of first material ball files can be determined in a material ball rendering tool. For example, when obtaining the ball attribute corresponding to the first ball file, the tool such as maya/3Dmax may click on the position corresponding to the first ball file, and at this time, the ball attributes corresponding to the plurality of first ball files may be determined according to the prompt information; or a plurality of first material ball files corresponding to the character models can be obtained through the material ball rendering tool, and the material ball attributes corresponding to the first material ball files are extracted according to the first material ball files. Note that, the manner of obtaining the material ball attribute is not particularly limited in this disclosure.
After the material ball attributes corresponding to the plurality of first material ball files are obtained, the plurality of first material ball files can be combined into one or more second material ball files according to the material ball attributes. Specifically, the first material ball files with the same material ball attribute may be combined together. Note that, the manner of merging the first material balls is not particularly limited in this disclosure. The number of material ball files can be reduced, the number of draw calls can be reduced, and the frame rate of the game can be improved.

step S310, obtaining the similarity of the material ball attributes among a plurality of first material ball files;
In an example embodiment of the present disclosure, a similarity of material ball properties between a plurality of first material ball files may be obtained. Specifically, a specific value of a material ball attribute of the first material ball file may be obtained, where the closer the specific value of the material ball attribute is, the higher the similarity of the material ball file is.
For example, the transparency of the ball file a is 50%, the transparency of the ball file B is 60%, and the transparency of the ball file C is 60%, so that the similarity between the ball attributes of the ball file a and the ball attributes of the ball file B is greater than the similarity between the ball attributes of the ball file a and the ball attributes of the ball file C. The similarity of the ball properties between the first ball files may be numerically characterized. Note that, the method for obtaining the similarity of the material ball attributes among the plurality of first material ball files is not particularly limited in this disclosure.
Step S320, merging the first material ball files with similarity greater than or equal to the second preset value to obtain one or more second material ball files.

Specifically, the second preset value may indicate that the similarity of the material ball attributes of the material ball files is higher, and at this time, the material ball files may be combined.
The second preset value can be adjusted according to the service scene, and the second preset value is stored in the terminal equipment or the server, and when the similarity of the material ball attributes between the first material ball files is required to be compared with the second preset value, the second preset value is called from the terminal equipment or the server. It should be noted that, the specific numerical value of the second preset value is not particularly limited in this disclosure.
Through the steps S310 to S320, the similarity of the material ball attributes among the plurality of first material ball files can be obtained, and the first material ball files with the similarity greater than or equal to the second preset value are combined to obtain one or more second material ball files.
Step S230, baking the animation data into the map to obtain a map file with the animation data;
In one example embodiment of the present disclosure, after the animation data corresponding to the character model is obtained, the animation data may be baked into a map to obtain a map file with the animation data. Specifically, the change information of the vertex data of the character model may be included in the map file of the animation data. At this time, the animation data is not calculated by the CPU, but is calculated by the GPU (graphics processor, graphics processing unit), so that the calculation pressure of the CPU is greatly reduced, and the game performance is improved.
In one example embodiment of the present disclosure, animation data corresponding to a character model may be baked into a map file of animation data, and when baking is performed, the animation data corresponding to the character model may be baked into a map file of animation data by an animation baking tool. For example, the animation data corresponding to the character model may be baked into a map file of animation data by DCC software such as tools such as maya/3 Dmax and related plugins (e.g., vertex Anim Toolset plugins in UE 4). The specific manner of baking the animation data into the map to obtain the map file with the animation data is not particularly limited in the present disclosure.
Step S240, generating a blueprint comprising a plurality of action nodes according to the mapping file, wherein the action nodes are used for indicating the positions of actions in the mapping file;
In one example embodiment of the present disclosure, a blueprint including a plurality of action nodes may be generated from a map file. Wherein, the blueprint can be used for driving the character model to switch states, namely, driving the character model to execute actions corresponding to the animation data. Specifically, a plurality of map files are stored in the blueprint, and the state switching can be performed by driving the character model through the map files. Specifically, the blueprint further comprises a plurality of action nodes, and the action nodes can be used for indicating the positions of actions in the mapping file, namely, the actions to be applied can be searched in the mapping file through the action nodes.
Further, the action nodes may also be used to indicate a switching relationship between actions. Specifically, the next action to be switched can be known by the action node, or the specific position of the next action to be switched in the map file can be known by the action node, or the switching time can be known by the action node. The specific form of the switching relationship is not particularly limited in this disclosure.
Specifically, the action nodes comprise example object random nodes, vector nodes and judging nodes. Wherein the example object random nodes are used to randomly determine an initial action from the map file for the character model; the vector node is used for determining other actions except the initial action from the mapping file; the judging node is used for determining the action to be switched and the switching time from the mapping file, for example, when the character model meets the action triggering condition, the character model can be controlled to make corresponding action.
Specifically, when the character model is driven to switch states by the map file, vertex data of the character model can be acquired in the map file. For example, the model vertex data can be directly accessed by the vertex detection plugin, and also can be determined by a manual labeling mode. And then recording the model vertex data corresponding to the character model of each time unit according to the time change, or recording the model vertex data corresponding to the character model in sequence according to the sequence of the key frames. It should be noted that, the method for obtaining the model vertex data is not particularly limited in this disclosure. After the model vertex data corresponding to the map file is obtained, the motion of the character model can be controlled according to the model vertex data corresponding to the map file. In particular, the current character model may be controlled to move in accordance with changes in model vertex data.
For example, the character model includes a vertex a with coordinates (15, 20, 15), and the vertex a corresponding to the first time unit in the map file has coordinates (15, 20, 20), then the vertex a of the character model is moved to the position (15, 20, 20), and so on, all vertices in the character model are moved according to the map file, so that the motion of the character model can be controlled by the model vertex data. The specific manner in which the character model is driven to switch states by the map file is not particularly limited in this disclosure.
And step S250, rendering the character model according to the second material ball file, the map file and the blueprint.
In one example embodiment of the present disclosure, the character model may be rendered from the second material ball file, the map file, and the blueprint. Specifically, after the second material ball file, the map file, and the blueprint are obtained through the steps, the character model may be rendered according to the second material ball file, the map file, and the blueprint. At this time, the number of material ball files is reduced, and the state switching is performed by using the map files and the blueprint to drive the character model, so that the calculation pressure of the CPU can be reduced, and the game performance can be improved.
In one example embodiment of the present disclosure, the aspects of the present disclosure may be used in an application scenario for clustering character models. Wherein multiple character models may be included in a clustered character model. As shown in FIG. 4, multiple character models may be included in a clustered character application scenario.
In one example embodiment of the present disclosure, the second material ball file, the map file, and the blueprint corresponding to the character model may be generated in a batch manner by instantiating the mesh model. Specifically, in the application scenario of the cluster game, if multiple character models are to be added, the number of draw calls is more, and at this time, the second material ball file, the map file and the blueprint corresponding to the character model may be generated in batches by using the instantiation grid model, and the cluster character model may be rendered according to the second material ball file, the map file and the blueprint. Specifically, the instantiation grid model (INSTANCEMESH) can call the existing second material ball file, map file and blueprint, so as to achieve the purpose of generating the second material ball file, map file and blueprint in batches, and the inventor of the application finds that when 216 character models are generated in batches without using the instantiation grid model, the game frame rate is 51, and when 900 character models are generated in batches by using the instantiation grid model, the game frame rate is 53, and the calculation pressure of cpu (central processing unit ) is reduced due to the fact that the character models are generated in batches by using the instantiation grid model, so that the game performance is ensured.
In one example embodiment of the present disclosure, the actions of multiple character models may be controlled by a centralized control architecture. Specifically, in processing actions of multiple character models, all of the character models can be controlled by a single overall console due to the large number of character models. For example, when a character model collides within a game scene, the collision information may be sent to a console, which in turn controls the character model to react accordingly (e.g., avoid). Through the centralized control architecture, the running performance of the game can be improved.
In an example embodiment of the present disclosure, the centralized control architecture may include an Entity-Component-System (ECS) architecture, which follows a combinatorial-over-inheritance principle, each role model being an Entity, each Entity in turn being made up of one or more components, each Component containing only data representing its characteristics (i.e., no method in the Component), the System being a tool to handle a collection of entities having one or more identical components, which have only behavior (i.e., no data in the System), the Entity and the Component being in a one-to-many relationship, the behavior of the Entity being changed at run-time by dynamically adding or deleting components. The ECS architecture is a data-oriented design, and can process data in parallel, so that the processing speed is improved.
In an example embodiment of the present disclosure, the second material ball file, the map file, and the blueprint corresponding to the character model may be stored in the component in a coarse manner, and the execution action corresponding to each character model may be controlled by the system. Specifically, the components in the ECS architecture have no specific behavior, and when the role model needs to be controlled to execute an action, the system needs to send a command to the component corresponding to the action, and the system sends the command to the corresponding component to control the component corresponding to the role model to complete the corresponding action. The ECS architecture optimizes the rendering efficiency of the CPU end, improves the running frame rate of the game, and further improves the stability of the game.
In one example embodiment of the present disclosure, the action trigger instructions corresponding to each character model may be monitored, and after the action trigger instructions for a particular character model are received, the action trigger instructions may be sent to the system of the ECS architecture. Specifically, the character model receives an action trigger instruction in an application scenario (game scenario). For example, in an instant strategy game, when a player-controlled character is located a distance from a hostile character (non-player character, npc, non-PLAYER CHARACTER), an action trigger command for the hostile character may be monitored, where the action trigger command is aimed at causing the current hostile character to attack the player-controlled character. At this point, an action trigger instruction may be sent into the ECS architecture system.
When the system receives the action trigger instruction, the component corresponding to the character model can be controlled to switch to the action corresponding to the action trigger instruction. Specifically, the system can send a command for executing the action to the component corresponding to the action triggering command, so that the component corresponding to the character model is switched to the action corresponding to the action triggering command, and the character model is controlled to make the corresponding action. Where each character model acts as an entity, it may have one or more components, each of which may carry different actions.
For example, in an instant strategic game, when a player-controlled character is close to an a-distance from a hostile character (character model), the hostile character may make an a-action (e.g., vigilance tense) corresponding to the a-component, and when a player-controlled character is close to a B-distance from the hostile character (character model), the hostile character may make a B-action (e.g., attack the player-controlled character) corresponding to the B-component.
In an example embodiment of the present disclosure, a character model may be imported, a plurality of first material ball files corresponding to the character model may be obtained, the plurality of first material ball files may be combined to obtain animation data corresponding to the character model, the animation data may be baked into a map, the character model may be generated in batches by instantiating a mesh model, and the actions of the character model may be centralized. Referring to fig. 5, a method for processing a character model of the present disclosure may include the following steps S510 to S570:
Step S510, importing a character model; step S520, a plurality of first material ball files corresponding to the character model are acquired; step S530, combining the plurality of first material ball files; step S540, obtaining animation data corresponding to the character model; step S550, baking the animation data into the map; step S560, generating character models in batches by instantiating the grid models; step S570, the actions of the character model are collectively processed.
In the method for processing the character model provided by the embodiment of the disclosure, a character model to be processed, a plurality of first material ball files and animation data corresponding to the character model can be obtained, the first material ball files are combined to obtain one or more second material ball files, the animation data are baked into a map to obtain the map file with the animation data, a blueprint comprising a plurality of action nodes is generated according to the map file, the action nodes are used for indicating positions of actions in the map file, and the character model is rendered according to the second material ball files, the map file and the blueprint.
According to the embodiment of the disclosure, the material ball files corresponding to the character model can be combined, the animation data are baked into the map file, and the character model is rendered through the combined material ball files, the map file and the blueprint. On one hand, the number of material balls of the character model can be reduced, the number of DRAW CALLS is reduced, the rendering speed is improved, and the game frame rate is improved; on the other hand, the animation data is baked into the map, and a plurality of actions of the character are realized through the animation map, so that the operation pressure of the CPU can be reduced, and the game performance can be improved.
