In order to make the solution of the present application easier to understand, the following explains some concepts involved in the present application:
the virtual scene is a virtual scene displayed when an application runs on the terminal. The virtual scene may be a simulation environment of a real world, a semi-simulation semi-fictional virtual environment, or a pure fictional virtual environment. The virtual scene may be any one of a two-dimensional virtual scene, a 2.5-dimensional virtual scene, or a three-dimensional virtual scene.
The virtual character is a virtual portrait with high reality drawn by a modeling rendering technology. The virtual character is not limited to a human character, and may be a character such as an animal. Wherein the virtual character comprises a player character.
The player role refers to a role controlled by a player in a role-playing game.
A non-player character refers to a game character that is not manipulated by a real player in a game, and is generally controlled by artificial intelligence of a computer, and is a character having its own behavior pattern.
When the game-related application program is run, the display card of the terminal device renders and displays the virtual scene and the virtual character of the application program on the screen of the terminal device. When the virtual character is rendered, in order to improve the display effect of the virtual character, the virtual character is subjected to illumination rendering according to the position, the illumination direction, the illumination color and the like of a light source in a virtual scene. Generally, there are three light effects formed by illumination rendering, namely direct illumination, indirect illumination and sub-surface scattering formed by direct illumination or indirect illumination. In order to make the virtual character more three-dimensional, three illumination effects of direct illumination, indirect illumination and sub-surface scattering are added to the human body model of the virtual character for rendering, so that the virtual character displayed finally is more three-dimensional and real, and the skin texture details on the human body model can be displayed. However, rendering a virtual character by superimposing three illumination effects requires three different illumination calculations for the virtual character, and in a large-scale network Game, such as a Multiplayer Online Role Playing Game (mmoptg), hundreds of virtual characters may need to be simultaneously displayed on a terminal screen, at this time, if three different illumination calculations are performed for each virtual character, a GPU of a display card may need to perform thousands of calculations, the calculation amount is large, and the calculation amount may exceed an upper limit of the calculation capability of the GPU of the display card, so that the drawing speed of the display card is reduced, a phenomenon that a picture displayed on the screen of the Game is delayed, and a phenomenon that the Game is flashed off and the display card is damaged, which affects player experience.
In order to solve the above technical problems, embodiments of the present application will be described in detail below with reference to the accompanying drawings. The virtual role rendering method provided by the embodiment of the application is applied to an environment comprising terminal equipment, a plurality of database instances and a plurality of storage instances. The above example may be a virtual machine, a container, or a server, and in the embodiment of the present application, a server is taken as an example for description. FIG. 1 is a diagram of an application environment of a method for rendering virtual characters in one embodiment. In the application environment, the terminal device 110 is connected to the server 120 through a network, the terminal 110 may specifically be a desktop terminal 110 or a mobile terminal 110, and the mobile terminal may be one of a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. The server 120 may be implemented by an independent server 120 or a server cluster composed of a plurality of servers 120, and may also be a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a web service, cloud communication, middleware service, a domain name service, a security service, a CDN, and a big data and artificial intelligence platform. In this embodiment, the terminal device 110 may be used as a front end of a game client running a game, and the server 120 may be used as a background of the game client, so that after the server 120 obtains a data call request sent by a game player in the terminal device 110 through the game client, a long connection may be quickly established with the terminal device 110.
The terminal device 110 is loaded with a game, and when the game runs, before entering a virtual scene, a role display interface is entered; or after entering the virtual scene, the terminal device 110 responds to the interface switching operation of the player, and if a click operation initiated by the player in the designated area is received through a display screen of the terminal device 110, the character display interface is entered. In the role display interface, a plurality of human body models with different target light effects are displayed, wherein the target light effects comprise one or two of direct illumination, indirect illumination and sub-surface scattering. After entering the character display interface, the terminal device 110 receives a selection operation of a player for any one of the human body models, marks the selected human body model as a target human body model, obtains a target light effect corresponding to the target human body model, and renders each virtual character obtained from the memory of the terminal device 110 and the server 120 in the current virtual scene according to the target light effect corresponding to the target human body model. Wherein each virtual character comprises a player character and a non-player character. The determination of the current virtual scene is to obtain the character information and the operation information of the player character from the server 120 according to the operation of the player or through the communication link, for example, to move the player character to a target direction or a target point, so that the terminal device 110 may determine the current virtual scene according to the character information and the operation information of the player character and display the current virtual scene on the display interface; alternatively, the terminal device 110 may also directly obtain the current virtual scene from the memory of the terminal device 110 or from the server 120 and display the current virtual scene on the display interface according to a request or an instruction of the player, such as a selection operation for a game map. The memory or the server executes the operation according to the instruction or the request, which belongs to the prior art, so that the content or the form of the instruction or the request is not particularly limited.
Less light effects are added to each virtual character in the current virtual scene, so that the calculation amount of a display card when a plurality of virtual characters are displayed is reduced, the display speed of a terminal screen to the virtual characters is increased, the light effects needing to be added can be determined by a player, the calculation amount is reduced, the final display effect can meet the requirements of the player as far as possible, and the game experience of the player is guaranteed.
Hereinafter, the virtual character rendering method provided by the embodiments of the present application will be described and explained in detail through several specific embodiments. As an alternative embodiment, the method may be performed by the terminal device, or by both the server and the terminal device.
As shown in FIG. 2, in one embodiment, a method of virtual character rendering is provided. The embodiment is mainly illustrated by applying the method to computer equipment. The computer device may specifically be the terminal device 110 in fig. 1 described above.
Referring to fig. 2, the virtual character rendering method specifically includes the following steps:
s11, responding to selection operation of a player for a target human body model in each human body model, and obtaining target light effects corresponding to the target human body model, wherein different target light effects are added to each human body model respectively, and the target light effects comprise one or two of direct illumination, indirect illumination and sub-surface scattering.
In an embodiment, after a display screen of the terminal device enters a role display interface, a plurality of human body models are displayed in the role display interface, and different target light effects are added to each human body model. Since the sub-surface scattering needs to be formed by illumination, and the target light effect of the single sub-surface scattering cannot be formed, the role display interface comprises a human body model added with direct illumination, a human body model added with indirect illumination, a human body model added with direct illumination and sub-surface scattering, and a human body model added with indirect illumination and sub-surface scattering. Each human body model is displayed in different areas of the character display interface, and the size of each area is the same, so that a player can conveniently observe the human body models. In order to enable the player to conveniently observe the human body model added with the target light effect, the background of the character display interface adopts a dark background color, such as black. After a plurality of human body models are displayed, the selection operation of a player for any one of the human body models is received, wherein the selection operation comprises clicking operation on the area where the human body model is located, or inputting the number of the area where a certain human body model is located in an information input column in a role display interface, so that the selection operation on the human body models is realized, and the like. And when the selection operation is received, taking the human body model selected by the selection operation as a target human body model, and extracting the target light effect added by the target human body model from a memory of the terminal equipment or a server. And if the light effect added by the target human body model is direct illumination, extracting data representing the direct illumination.
In order to eliminate other interferences, a user determines a target human body model to be selected according to a target light effect, in one embodiment, each human body model is generated by adding different target light effects to an initial model of the same virtual character. Wherein the initial model is a basic model without any added light effect. As the player pays more attention to the character controlled by the player in the game process, each human body model can be generated by adding different target light effects to the initial model of the player character. Different target light effects are added to the initial model of the same virtual character to generate each human body model, so that the target light effects are the only variables, and the player can conveniently display and compare the target light effects.
And S12, rendering each virtual character in the current virtual scene according to the target light effect.
In an embodiment, after the target light effect is determined, virtual characters in the current virtual scene displayed by the display screen are rendered through the target light effect. Each virtual role may be all virtual roles in the current virtual scene, or all virtual roles within a certain specific range in the current virtual scene. When all the virtual characters in a certain range are selected, the certain range can be selected by a player according to actual needs, or preset by an application program.
In one embodiment, when the target light effect is direct illumination, the front highlight and the back shadow can be formed by adding parallel light towards the front of each virtual character in the current virtual scene in real time, and adding parallel light towards each virtual character in real time. Wherein adding parallel light to each virtual character toward the front of each virtual character, and adding parallel light to each virtual character, can be performed synchronously or asynchronously. When the target light effect is indirect illumination, acquiring indirect illumination brightness corresponding to each vertex on an environment map appointed in the current virtual scene in real time according to the normal direction of each vertex on the surface of the virtual character in the current virtual scene, multiplying the indirect illumination brightness of each vertex with the color value of each vertex to obtain the indirect illumination brightness on each virtual character, and adding indirect illumination to each virtual character by using the indirect illumination brightness on each virtual character. When the target light effect is the combination of direct illumination and sub-surface scattering, the added back parallel light penetrates through the sub-surface scattering of the partial models of the virtual characters according to the added back parallel light of the direct illumination in real time. Similarly, when the target light effect is the combination of indirect illumination and sub-surface scattering, the sub-surface scattering of the partial model of each virtual character is penetrated by the added indirect illumination according to the indirect illumination in real time.
Less light effects are added to each virtual character in the current virtual scene, so that the calculation amount of a display card when a plurality of virtual characters are displayed is reduced, the display speed of a terminal screen to the virtual characters is increased, the light effects needing to be added can be determined by a player, the calculation amount is reduced, the final display effect can meet the requirements of the player as far as possible, and the game experience of the player is guaranteed.
To further alleviate the operating and computational stress, the above embodiment, as shown in fig. 3, for S12, includes:
and S21, matching the target light effect with the skin map set of each virtual character in the material library, and acquiring each target map matched with the target light effect from the skin map set, wherein each target map corresponds to each virtual character one to one.
In an embodiment, the set of skin maps of the virtual character is stored in a material library, wherein the material library may be stored in a server or cached in the terminal device. Different skin maps in the skin map set of the virtual character in the material library are template images for realizing the realistic effect of the skin of the virtual character. Different skin maps in the skin map set of the virtual character in the material library can be obtained by rendering, calculating and modeling through different target light effects in advance, or obtained by hand drawing in advance, or obtained by making an application program for drawing a graph in advance, and then stored, so that the different skin maps can be directly called as required when a game runs. In addition, different skin maps of virtual characters in the material library are associated with target light effects adopted when the skin maps are obtained and skin rendering is carried out, and if direct illumination is adopted for carrying out skin rendering to obtain the skin map 1, the direct illumination is associated with or bound to the skin map 1. I.e. the skin map 1 can be determined from direct illumination. The binding or association of the target light effect with the skin map is not particularly limited.
And S22, rendering each virtual character according to each target map.
In an embodiment, the terminal device renders the skin area of the virtual character in the current virtual scene according to the obtained target maps of the virtual characters. The method comprises the steps that a skin area of a virtual character is rendered according to a target map, the same content as the target map can be generated on the skin area according to the content of the target map, and then the target character is generated; and mapping processing can be carried out in the skin area through the target mapping to obtain the target character.
By matching the target light effect with the skin map set in the material library and rendering each virtual character in the current virtual scene according to the target map matched with the target light effect, a large amount of module surface number calculation and complex program algorithms do not need to be carried out in real time, and therefore when each virtual character is displayed on the terminal, the operation and calculation pressure of the terminal can be relieved, and the efficiency of displaying each virtual character is improved.
In order to highlight details of the virtual character and improve the display effect, in an embodiment, after rendering each virtual character in the current virtual scene, depth of field processing is performed on each virtual character.
In one embodiment, after rendering of the virtual character is completed, an image of the virtual character may be obtained. By carrying out depth of field processing on the image of the virtual character, the details of the human body model can be highlighted, and the depth of field effect formed by the imaging principle of a real camera can be simulated.
In an embodiment, each virtual character rendered according to the target light effect includes a first virtual character which is a player character operated by the target terminal and a plurality of target virtual characters selected from among the second virtual characters which include a non-player character and a player character operated by the non-target terminal. The first virtual role is a target terminal, i.e., a player role operated by the terminal device 110, i.e., a virtual role played and controlled by a player in a massively multi-player online role-playing game. The player can input operation into the terminal device through an input device such as a keyboard, a game handle and the like, and the terminal device generates corresponding operation according to the operation input by the user so as to control the first virtual character. The player character operated by the non-target terminal among the second virtual characters refers to a virtual character operated by a terminal other than the terminal device 110.
In order to control the number of virtual roles to be rendered, and thus prevent the display card from being damaged due to uncontrollable operation amount, in an embodiment, a plurality of target virtual roles are determined after being sequentially selected from the second virtual roles according to the distance between the first virtual role and each second virtual role in the current virtual scene, and the number of the target virtual roles meets a preset condition. As an example of this embodiment, according to the distances between each second virtual character and the first virtual character, multiple target characters may be selected from the second virtual characters in an order from small to large, where, if there are 3 second virtual characters in the current game scene, and the distance between the first virtual character and the 3 second virtual characters is 2m, 3m, and 1m, the second virtual character with the distance between the first virtual character and the first virtual character being 1m is selected first, the second virtual character with the distance between the first virtual character and the first virtual character being 2m is selected, and finally the second virtual character with the distance between the first virtual character and the first virtual character being 3m is selected until the number of the selected second virtual characters meets a preset condition, the selection is stopped, and each selected second virtual character is marked as a target virtual character. The preset condition is used for setting the number of the second virtual roles to be selected. And if the number of the second virtual roles in the current virtual scene is more than or equal to the number in the preset conditions, sequentially selecting the number of the second virtual roles limited by the preset conditions from small to large according to the distance between each second virtual role and the first virtual role. If 13 second virtual characters exist in the current virtual scene and the number of the second virtual characters to be selected is 10, the terminal device sequentially selects 10 second virtual characters from the current virtual scene according to the sequence of the position information from small to large. When the position distances between the plurality of second virtual characters and the first virtual character are the same, and if the number of the plurality of second virtual characters with the same position distance is larger than the number limited by the preset condition, the terminal device may randomly select one or more second virtual characters from the plurality of second virtual characters with the same position distance until the preset condition is met, for example, 13 second virtual characters exist in the current virtual scene, the number of the second virtual characters to be selected limited by the preset condition is 10, and after the 9 second virtual characters are sequentially selected from small to large according to the position information, the distances between the remaining 4 second virtual characters and the first virtual character are 10m, at this time, the terminal device may randomly select one of the 4 second virtual characters to meet the number requirement of 10 limited by the preset condition; the terminal device may also stop selecting 9 second virtual characters. And if the number of the second virtual roles existing in the current virtual scene is smaller than the number in the preset condition, the terminal equipment sequentially selects all the second virtual roles from small to large according to the position distance between each second virtual role and the first virtual role, and then stops selecting.
Because the plurality of target virtual characters meeting the preset condition number are selected to perform subsequent rendering processing through the distance between the first virtual character and each second virtual character in the current game scene, the number of the virtual characters needing the subsequent rendering processing can be controlled in the game scene with a large number of virtual characters, the calculation amount required by the GPU of the display card can be controlled, the calculation capacity of the GPU of the display card is prevented from exceeding the upper limit, the damage of the display card is further avoided, and the calculation amount of the GPU of the display card is reduced.
When each virtual character rendered according to the target light effect includes a first virtual character and a plurality of target virtual characters selected from second virtual characters, in an embodiment, as shown in fig. 4, a flowchart of a virtual character rendering method in another embodiment is shown. In this embodiment, in addition to the steps shown in fig. 2, the method further includes:
s13, when each virtual character rendered according to the target light effect includes the first virtual character and a plurality of target virtual characters selected from the second virtual characters, stopping the rendering and displaying process for the non-target virtual characters except the target virtual character in the second virtual characters.
In an embodiment, after the selection of the target virtual character is completed, the remaining second virtual characters are far away from the first virtual character, and the attention of the player to the second virtual character is not high, so that the terminal device stops the rendering and displaying process of the non-target virtual character in each second virtual character after the selection of the target virtual character is completed.
After the target virtual character is selected, the drawing and display process of the remaining second virtual character is stopped, so that the GPU operation amount of the display card is reduced, and meanwhile, when the display card performs target light effect rendering on the virtual character in the current game scene, the peak value of the GPU operation amount is determinable, and the damage of the GPU of the display card due to uncontrollable operation amount is avoided.
It is to be understood that, in performing S14, the depth of view processing of the avatar in the above-described embodiment may be performed synchronously, or S14 and the depth of view processing of the avatar may be performed asynchronously.
