DETAILED DESCRIPTION

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

The components of the embodiments of the present application generally described and shown in the drawings herein may be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

In addition, the flowchart used in this application shows the operations implemented according to some embodiments of the present application. It should be understood that the operations of the flowchart can be implemented out of order, and the steps without logical context can be reversed in order or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flowchart under the guidance of the content of this application, and can also remove one or more operations from the flowchart.

In order to enable those skilled in the art to use the content of this application, the following implementation is given in conjunction with a specific application scenario: the rendering of a game scene as an example. For those skilled in the art, the general principles defined herein can be applied to other embodiments and application scenarios without departing from the spirit and scope of this application. Although this application is mainly described around the rendering of a game scene, it should be understood that this is only an exemplary embodiment.

It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

To facilitate understanding of this application, some terms involved in this application are explained as follows:

Shader: Shader stores the GPU's execution code, which is used to tell the GPU how to draw the color of the target pixel. It is widely used in the field of 3D graphics. Various 3D graphics effects can be obtained through shader code.

Direct light: The light that directly shines from the light source to the object is called direct light.

Indirect light: In the real world, objects can be illuminated by indirect light. Indirect light means that light usually reflects between multiple objects and finally enters the camera, which means that before the light enters the camera, it is reflected by more than one object.

Physical Based Rendering (PBR): It is a real-time rendering method widely used in recent years. The corresponding material system is called PBR material system, which includes multiple parameters such as base color, metallic, roughness, etc.

Image Based Lighting (IBL): In the PBR system, specular reflection is achieved through IBL technology. The effect of ambient light in real-time rendering is achieved by using environment maps (which can be taken by a camera in the real world or rendered in real time by a camera in the game).

Rendering pipeline: The rendering pipeline is the core component of real-time rendering. The function of the rendering pipeline is to render a two-dimensional image by giving a virtual camera, three-dimensional scene objects, light sources and other scene elements.

It is worth noting that before the present application was filed, in order to illuminate the scene, the prior art usually used direct light and indirect light in the game engine. In order to prevent the part not illuminated by direct light from appearing "dead black", that is, to highlight the details of the dark area, the light source or the environmental reflection would be used to interact with the object, that is, the light generated by the direct light and the indirect light needs to interact with the surface of the object, so as to obtain the rendering and shading results and display them. However, this method will not only increase the performance consumption, but also in some game scenes, such as water, ice and smooth snow, it will be difficult to balance the contrast between the bright and dark parts, resulting in the problem that the artist has adjusted the bright parts but the dark parts are overexposed or the dark parts are adjusted but the details of the bright parts are not obvious.

The game scene rendering method provided in the present application can directly obtain the first material rendering parameter and the second material rendering parameter of the material shader of the object to be rendered, and perform material rendering on the directly lighted area and the area not directly lighted according to the first material rendering parameter and the second material rendering parameter, respectively. There is no need to perform additional lighting processing on the area not directly lighted. The effects of the directly lighted area and the area not directly lighted in the game scene can be adjusted in a simple manner, thereby balancing the contrast between the directly lighted area and the area not directly lighted, avoiding the "dead black" effect of the area not directly lighted, and improving the rendering effect of the game scene. It can also solve the problem in the prior art that the light generated by direct light and indirect light interacts with the surface of an object to obtain the final rendering and shading effect and display it, resulting in high performance consumption, thereby simplifying the rendering process of the game scene.

The following is an explanation of a game scene rendering method provided by an embodiment of the present application in combination with multiple specific application examples. FIG1 is a flow chart of a game scene rendering method provided by an embodiment of the present application. As shown in FIG1 , the method includes:

S101: Obtaining a first material rendering parameter and a second material rendering parameter of an object to be rendered through a material shader of the object to be rendered in a game scene.

In the method provided in the present application, since the material shader includes a first material rendering parameter and a second material rendering parameter, the material shader provided in the present application can obtain two parts of material rendering parameters for the object to be rendered, and according to the two parts of material rendering parameters, render the materials corresponding to the bright and dark areas respectively.

S102: Performing material rendering on a directly illuminated area of the object to be rendered using a physically based rendering method according to the first material rendering parameter.

Optionally, material rendering can be performed on objects corresponding to all direct light illumination areas in the game scene according to the first material rendering parameters; or, according to the first material rendering parameters and in combination with a user's selection operation, material rendering can be performed only on a few selected objects in the direct light illumination area in the game scene; or, according to the first material rendering parameters and in combination with a user's selection operation, material rendering can be performed only on multiple objects of a selected target type among multiple types of objects in the direct light illumination area in the game scene; the method for determining the specific material rendering object can be flexibly adjusted according to user needs, and is not limited to the above-mentioned embodiments.

The directly illuminated area in the game scene is the bright area of the current scene. Material rendering is performed on the directly illuminated area based on the first material rendering parameter, which ensures the rendering effect of the bright area. In this way, the rendering effect of the bright area can be controlled by configuring or changing the first material rendering parameter.

S103: performing material rendering on the area of the object to be rendered that is not illuminated by direct light, using a physically based rendering method according to the second material rendering parameter.

Optionally, in some possible embodiments, the method of performing material rendering on areas not illuminated by direct light may be, for example: performing material rendering on objects corresponding to all areas not illuminated by direct light in the game scene; or performing material rendering on only a few selected objects in areas not illuminated by direct light in the game scene based on user selection; or performing material rendering on only multiple objects of a selected target type among multiple types of objects in areas not illuminated by direct light in the game scene based on user selection; the determination of specific material rendering objects may be flexibly adjusted based on user needs and is not limited to the above embodiments.

Among them, the area in the game scene that is not directly illuminated by light due to occlusion and other reasons is the dark area of the current scene. For example, some areas blocked by high-rise buildings or plants, or areas in caves or indoors with no light source at all are the dark areas in the current game scene. The second material rendering parameter is used to control the rendering effect of the dark area.

By adopting the game scene rendering method provided by the present application, since the rendering is performed by directly obtaining the first material rendering parameter and the second material rendering parameter of the material shader of the object to be rendered, and material rendering is performed on the directly illuminated area and the not directly illuminated area in the game scene according to the first material rendering parameter and the second material rendering parameter, there is no need to perform additional lighting processing on the not directly illuminated area in the game scene. The effects of the directly illuminated area and the not directly illuminated area in the game scene can be adjusted in a simple manner, thereby balancing the contrast between the directly illuminated area and the not directly illuminated area in the game scene, thereby avoiding the "dead black" effect of the not directly illuminated area, improving the rendering effect of the game scene, and ensuring the layering effect between the directly illuminated area and the not directly illuminated area in the game scene after rendering, and the rendering effect is more realistic.

Optionally, based on the above embodiment, the embodiment of the present application may also provide a game scene rendering method. The following is an example of the implementation process of obtaining material rendering parameters in the above method in conjunction with the accompanying drawings. Figure 2 is a flowchart of a game scene rendering method provided by another embodiment of the present application. As shown in Figure 2, S101 may include:

S104: Obtaining a first material rendering parameter through a first configuration area on a configuration interface of a material shader.

Among them, the first configuration area is used to receive the first material rendering parameters. For example, the first configuration area can be displayed at a corresponding position pre-set in the setting interface in the form of a setting interface. The user can determine that the user-input parameters obtained are the first material rendering parameters by entering parameters in the first configuration area.

S105: Obtain second material rendering parameters through a second configuration area on a configuration interface of the material shader.

Among them, the first configuration area is used to receive the first material rendering parameters. In some possible embodiments, for example, the second configuration area can be displayed at a corresponding position pre-set in the setting interface in the form of a setting interface (wherein the first configuration area and the second configuration area are different areas on the setting interface). The user can determine that the user-input parameters obtained are the second material rendering parameters by entering parameters in the second configuration area.

Optionally, the first material rendering parameter and the second material rendering parameter can be manually configured by an artist, or can be determined by the artist through selection operations in preset configuration options. The specific method of determining the material rendering parameters can be flexibly adjusted according to user needs, and this application does not impose any restrictions here.

Optionally, based on the above embodiment, the embodiment of the present application may also provide a game scene rendering method. The following is an example of the implementation process of obtaining the first material rendering parameter in the above method in conjunction with the accompanying drawings. Figure 3 is a flowchart of a game scene rendering method provided by another embodiment of the present application. As shown in Figure 3, S104 may include:

S106: Receive a material map input through the first configuration area.

In some possible embodiments, the material map can be a material map selected from multiple material maps in a preset material map library, or a material map drawn by an artist, or a material map crawled from the Internet. The specific method of obtaining the material map can be flexibly adjusted according to user needs and is not limited to the above embodiments.

S107: Reading a first material rendering parameter from a preset channel in a material map.

Among them, the preset channel in the material map records the corresponding type of material rendering parameters, which are used to render the material of the directly illuminated area according to the corresponding type of material rendering parameters in the material map, so that if the material of the directly illuminated area needs to be changed, it is only necessary to change the corresponding material map.

In one embodiment of the present application, the first metalness value can be read from the R channel of the material map, and the first roughness value can be read from the G channel of the material map, that is, the metalness of the directly illuminated area is material rendered according to the read first metalness value, and the roughness of the directly illuminated area is material rendered according to the read first roughness.

Optionally, based on the above embodiment, the embodiment of the present application may also provide a game scene rendering method. The following is an example of the implementation process of obtaining the first material rendering parameter in the above method in conjunction with the accompanying drawings. Figure 4 is a flowchart of a game scene rendering method provided by another embodiment of the present application. As shown in Figure 4, S105 may include:

S108: Receive a preset type of material rendering parameter input through the second configuration area.

The second material rendering parameters include: material rendering parameters of a preset type.

Optionally, in one embodiment of the present application, the second configuration area has: an input box for at least one preset type of material rendering parameter; S108 is to receive each preset type of material rendering parameter input through the input box for each preset type of material rendering parameter: the second material rendering parameters include: at least one preset type of material rendering parameter.

For example, at least one preset type of material rendering parameter may include: a second metallic value, and/or a second roughness value. In one embodiment of the present application, at least one preset type of material rendering parameter includes: a second metallic value and a second roughness value; its value may be, for example, any value in the range of 0-1, wherein when the second metallic value is 0, it indicates that the effect corresponding to the current material is not metallic at all, and the closer the second metallic value is to 1, the stronger the metallic texture of the effect corresponding to the current material; the closer the second roughness value is to 0, the lower the roughness of the effect corresponding to the current material, that is, the smoother the effect corresponding to the current material, and the closer the second roughness value is to 1, the higher the roughness of the effect corresponding to the current material, that is, the less smooth the effect corresponding to the current material; however, it should be understood that for materials of the preset type, the specific contents included in the rendering parameters can be flexibly adjusted according to user needs, and are not limited to the above embodiments.

By adopting the method provided by the present application, compared with the method of only reading the first material rendering parameters in the prior art, the present application additionally adds a second material rendering parameter to replace the original method of only reading a set of parameters. Thus, the configuration of the bright and dark effects in the scene can be achieved through simple settings, without the need for complex processes such as interactive calculations based on direct light and indirect light. If the effects of the bright and dark parts need to be modified later, only simple modifications are required to achieve the modification of the bright and dark effects in the scene, thereby improving the work efficiency of artists.

Optionally, based on the above embodiment, the embodiment of the present application may also provide a game scene rendering method. The following is an example of the implementation process of material rendering for areas not directly illuminated by light in the above method in conjunction with the accompanying drawings. FIG5 is a flowchart of a game scene rendering method provided by another embodiment of the present application. As shown in FIG5, S103 may include:

S109: According to the second material rendering parameter, a highlight item of indirect light of a rendering pipeline based on a physically based rendering method is configured.

By adopting the method provided in the present application, since the PBR part in the rendering pipeline is improved, by processing the part of the IBL read in the PBR, the material shader of the object to be rendered can receive separate first material rendering parameters and second material rendering parameters, that is, in the method provided in the present application, the PBR needs to receive two different material rendering parameters, and then perform material rendering on different areas in the game scene according to the received different material rendering parameters, and the two different material rendering parameters are used to render the material effects of the bright area and the dark area in the current game scene, respectively; wherein, the highlight item of the IBL part of the indirect light of the PBR rendering pipeline can be configured according to the second material rendering parameter, for use in the subsequent highlight calculation in the IBL.

S110: Based on the configured rendering pipeline, material rendering is performed on the area of the object to be rendered that is not illuminated by direct light.

In an embodiment of the present application, the material rendering of the directly illuminated area (bright part) and the area not directly illuminated by light (bright part) are performed separately. Specifically, the target bright area is rendered according to the first material rendering parameter, and the target dark area is rendered according to the second material rendering parameter. The final shading effect in the scene includes the result of material rendering of the area illuminated by direct light and the result of material rendering of the area not directly illuminated by light.

The following is an example description in conjunction with the rendering of a virtual snow layer in a game scene. Figure 6 is a schematic diagram of a configuration interface provided by an embodiment of the present application. As shown in Figure 6, for example, the current game scene rendering method is used as an example for rendering a snow layer in a game scene: the object material shader configuration interface can be, for example, a terrain mosaic material shader configuration interface, and the configuration interface can include, for example, parameter configuration areas such as terrain standard parameters and snow basic color parameters. In addition, a second configuration area 130 can be additionally set in the object material shader configuration interface for receiving second material rendering parameters; at this time, in addition to the standard parameter and basic parameter configuration areas, the snow layer Snow Layer also has two layered configuration areas: a first configuration area 120 and a second configuration area 130, which are respectively used to read different metallicities and roughnesses corresponding to bright areas and dark areas, and perform subsequent material rendering on the objects to be rendered in the current game scene according to the read parameters.

Among them: the first layer is to read the first material rendering parameter through the first configuration area 120, that is, the snow layer mixing parameter SnowLayer Mix interface. The interface reads a material map, wherein the R channel in the material map stores the metalness value, and the G channel stores the roughness value. The first material rendering parameter is determined according to the two parameters read, and then the material rendering is performed on the bright area illuminated by direct light according to the first material rendering parameter. If the artist needs to modify the material effects of the two areas in the current game scene, the first material rendering parameter corresponding to the above interface can be modified directly by modifying the material map, thereby adjusting the material effect corresponding to the bright area in the current game scene.

The second layering is to read the second material rendering parameters through the second configuration area 130, namely the snow layer metallicity specification parameter SnowLayerSpecCubeMetallic interface and the snow layer roughness specification parameter SnowLayerSpecCube Roughness interface, and then perform material rendering on the dark area not directly illuminated by light according to the second material rendering parameters; the two interfaces in the above-mentioned second configuration area 130 are used to read the corresponding material rendering parameters, which respectively allow receiving a value ranging from 0 to 1, and different values correspond to different roughness or metallicity, which is used to subsequently process the metallicity and roughness of the dark area according to the values of the two interfaces read; in the process of configuring the game scene, if the artist needs to modify the material effect of the dark area in the current game scene, he can directly adjust the material effect corresponding to the dark area in the current game scene by modifying the material rendering parameters corresponding to these two interfaces in the first configuration area 120 and the second configuration area 130 corresponding to the parameter configuration interface.

In the method provided in the present application, the PBR calculation needs to receive two different metallicity and roughness values for processing the bright material effects and the dark material effects in the current game scene. In the IBL part, the required metallicity and roughness values are used to add a second configuration area in the present application, wherein the second configuration area includes two interfaces (SnowLayerSpecCube Metallic and SnowLayerSpecCube Roughness). When the method provided in the present application is used to modify the material effects in the current game scene, the bright material effects and the dark material effects can be modified by simply modifying the parameters, which simplifies the operation of the artists and allows the artists to control the bright and dark material effects in the game scene more easily.

By adopting the game scene rendering method provided by the present application, the target bright area and the target dark area are rendered respectively by configuring the first material rendering parameters and the second material rendering parameters in the first configuration area and the second configuration area. Compared with the traditional technology of rendering the dark area according to the interaction of direct light and indirect light, the rendering method provided by the present application is simple, easy to operate and easy to modify, which makes it convenient for artists to control the bright and dark effects of objects of any material in the game scene by adjusting the first material rendering parameters and the second material rendering parameters.
