Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the present embodiment, there is provided a game image processing method, as shown in fig. 1, the method including:
102, writing the three-dimensional scene resource data into a three-dimensional image cache of a target rendering pipeline, and rendering the three-dimensional scene resource data in the three-dimensional image cache through a three-dimensional rendering channel of the target rendering pipeline to obtain three-dimensional image cache data in a linear space, wherein the target rendering pipeline is obtained by adding a first conversion channel and a second conversion channel into a general rendering pipeline;

and 104, converting the color space of the UI rendering result into a linear space through the second conversion channel.
According to the embodiment of the application, under the condition that the UI material manufacturing workflow is not changed, the problem that color difference exists after the three-dimensional scene graph in the linear space and the interface UI graph manufactured in the gamma space are mixed is solved, the accuracy of the UI graph cannot be lost, and the image effect can be improved.
In the above embodiment, first, three-dimensional scene resource data of any target game scene in the game and interface UI material data that is pre-made corresponding to the scene are obtained, where the three-dimensional scene resource data may be obtained by a game developer by making the resource in a linear space through a game engine and by drawing the scene, and the interface UI material data may be obtained by making the interface UI material data in a gamma space through image processing software PS. Secondly, the data is written into a pre-constructed target rendering pipeline, which is obtained by adding two conversion channels for color space conversion to a general rendering pipeline. Rendering three-dimensional scene resource data in a three-dimensional image cache of a target rendering pipeline through a default three-dimensional rendering channel (such as Draw Object Pass), capturing the rendered three-dimensional image cache data, converting a color space of the three-dimensional image cache data from a linear space to a gamma space through a first conversion channel added in the pipeline in advance, transferring the color space to a UI cache of the gamma space, and simultaneously putting interface UI material data belonging to the gamma space into the UI cache so as to perform UI rendering. And finally, UI rendering is carried out on the three-dimensional image cache data and the interface UI material data which are placed in the UI cache through a default UI rendering channel in the target rendering pipeline, alpha mixing is carried out on the three-dimensional scene cache data and the UI material in the linear space in the gamma space through the UI rendering process, correct transparency can be ensured, then the final rendering result is converted back to the linear space through a second conversion channel which is added in the pipeline in advance, image output is carried out, and the RGB color of the finally output image is ensured to be the correct color for replacing the linear space. Because the alpha blending of the UI picture is completed in the gamma space, there is no wrong alpha blending result, and 3D rendering in the linear space and UI rendering in the gamma space are compatible.
By applying the technical scheme of the embodiment, three-dimensional scene resource data and interface UI material data are obtained, a pre-configured target rendering pipeline is called, then 3D rendering is carried out on the three-dimensional scene resource data through a default three-dimensional rendering channel in the target rendering pipeline, a color space of a 3D rendering result is converted into a gamma space through a first conversion channel, UI rendering is carried out on the 3D rendering result and the UI material through the default UI rendering channel under the gamma space, so that alpha mixing of the three-dimensional scene resource and the interface UI material is achieved, and finally the color space of the UI rendering result is converted into a linear space through a second conversion channel so as to be imaged. According to the embodiment of the application, the existing UI picture manufacturing workflow does not need to be changed, the drawing space of the UI material does not need to be manually adjusted, the color precision loss is avoided while the image manufacturing efficiency is improved, the problem that color difference exists after the current UI picture enters a game development engine to be rendered is solved, and the game expressive force is improved.
In the embodiment of the application, the user-defined general rendering pipeline is transformed, the UI rendering problem is solved by the transformed target rendering pipeline, and the normal sRGB asset manufacturing process of a UI designer is supported. Such as the universal rendering pipeline URP provided by game engine unit, which is currently a programmable rendering pipeline, supporting customization of the pipeline.
In this embodiment of the application, the target rendering pipeline may be obtained by modifying a general rendering pipeline in the game engine, as shown in fig. 2, optionally, the target rendering pipeline may be generated through the following steps:
s1, determining a universal rendering pipeline in the game engine;
s2, adding a first conversion channel for converting the color space from the linear space to the gamma space after the three-dimensional rendering channel of the general rendering pipeline, and adding a second conversion channel for converting the color space from the gamma space to the linear space after the UI rendering channel of the general rendering pipeline to obtain the target rendering pipeline.
The method and the device for achieving the universal rendering pipeline URP can be modified based on the universal rendering pipeline URP of the game development engine unit to obtain the target rendering pipeline, and the universal rendering pipeline URP comprises a plurality of universal rendering processes, such as a three-dimensional rendering channel (used for achieving 3D rendering), a UI rendering channel (used for achieving UI rendering), a post-processing process and the like. As shown in fig. 3, after determining the general rendering pipeline, a conversion channel of a color space is added after the three-dimensional rendering channel and the UI rendering channel, wherein a first conversion channel is added after a three-dimensional rendering channel 3D pass, for performing a conversion from a linear space into a gamma space, such that a color space of a 3D rendering result is converted from the linear space into the gamma space after 3D rendering, for subsequent alpha blending with UI in gamma space to get the correct transparency, and, in addition, adding a second conversion channel after the UI pass for converting the gamma space to the linear space, so that the color space of the UI rendering result is converted from gamma space into linear space after the UI rendering to make a graph in linear space, ensuring that the RGB colors are correct.
In this embodiment of the application, the rendering process in the rendering pipeline is implemented by a rendering camera, and optionally, the constructing process of the target rendering pipeline further includes:
when a new camera instruction for the target rendering pipeline is received, identifying whether a new camera indicated by the new camera instruction is a UI camera; if the newly-built camera is a UI camera, adding the newly-built camera at the tail of a camera stack of the target rendering pipeline; and if the newly-built camera is not the UI camera, inserting the newly-built camera in front of the UI camera in the camera stack of the target rendering pipeline.
In this embodiment, since the original color space of the rendering pipeline is a linear space, the space is converted to gamma before the UI is rendered in this embodiment, so that alpha blending can be performed to obtain the correctly blended transparency, but since the color (rgb channel) is converted into the space, there is a color difference, so that it is necessary to convert the UI camera into the linear space after the rendering is completed to finally obtain the correct color and transparency. However, if the UI camera is rendered by another camera, the transparency is rendered in the linear space, and the transparency still gets wrong transparency, so the UI camera rendering should be the last rendering process of the pipeline. As shown in fig. 4, taking the Camera Stack of the universal rendering pipeline URP of the game development engine unit as an example, if a Camera is to be newly built in the Camera Stack, the identity of the newly built Camera is confirmed first, if the Camera is a UI Camera for UI rendering, the Camera is added at the last side of the Camera Stack list, and if other cameras (for example, special effect cameras) are inserted in front of the UI Camera in the Camera Stack list, so as to ensure that the rendering order of the target rendering pipeline is 3D Camera- > other Camera- > UI Camera.
Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully explain the specific implementation process of the embodiment, another game image processing method is provided, as shown in fig. 5, and the method includes:
And 203, if not, traversing the UI canvas object corresponding to the target game scene to acquire the interface UI material data corresponding to the UI canvas object.
204, writing the three-dimensional scene resource data into a three-dimensional image cache of a target rendering pipeline, and rendering the three-dimensional scene resource data in the three-dimensional image cache through a three-dimensional rendering channel of the target rendering pipeline to obtain three-dimensional image cache data in a linear space; converting the color space of the three-dimensional image buffer data to a gamma space through the first conversion channel.
Optionally, the three-dimensional image cache data in the linear space obtained through the three-dimensional rendering channel is in a first data format; and the three-dimensional image cache data in the gamma space obtained through the first conversion channel is in a second data format.
In this embodiment, as shown in fig. 6, it is first determined whether a three-dimensional scene object, such as a 3D scene object, is included in the target game scene. If the data is contained in the interface UI material data, traversing a three-dimensional scene object in the scene, acquiring three-dimensional scene resource data, performing 3D rendering through a 3D pass, and converting three-dimensional image cache data (3D cache) in a linear space into a gamma space, wherein the cache format of the three-dimensional image cache data in the linear space can be RGB111110Float (a first data format), and the cache format can be RGBA32UNorm (a second data format) after the data is converted into the gamma space, and further traversing UI canvas objects in pre-made UI canvases, namely the UI canvas objects in FIG. 4, and acquiring the interface UI material data. And if the target game scene does not comprise the three-dimensional scene object, directly traversing the UI canvas to obtain UI material data.
In this embodiment, the color space of the UI material data is converted into the linear space before the UI is rendered, so as to ensure that the UI image can be previewed in the game development engine, ensure that the UI image can be color previewed under the editor, and possibly that part of the UI is rendered on the linear 3D cache as a 3D object (e.g. a monster blood bar), and converting the UI from the gamma space into the linear space can ensure that the UI can be accurately displayed in the linear space of the editor. In addition, the method can also be used for reversely correcting the interface UI materials converted into the linear space in the shader based on the existing flow in the pipeline, then sampling the UI subjected to the reverse correction and converting the UI back into the gamma space so as to perform UI rendering in the next step.
And step 206, putting the three-dimensional image cache data in the gamma space and the sampled interface UI material data into a UI cache.
And step 208, displaying a game image containing the three-dimensional scene resources and the interface UI materials based on the UI rendering result in the linear space.
Optionally, the UI rendering result in the linear space obtained through the second conversion channel is in a third data format.
In this embodiment, the three-dimensional image cache data converted into the gamma space is put into a UI cache as a UI material, UI rendering is performed in the UI cache together with the sampled interface UI material data, and finally, after the UI rendering is completed, the UI rendering result in the UI cache is converted into a linear space to obtain a UI rendering result in a third data format (e.g., RGBA32sRGB), and drawing is performed, and a game image including the three-dimensional scene resource and the interface UI material is displayed on a screen, so as to ensure that the color and the transparency of the game screen displayed on the screen are correct. Fig. 7 shows a rendering effect comparison diagram provided by the embodiment of the application, and as shown in fig. 7, a picture rendered by using the scheme has a better transparency effect than a picture rendered by a current 3D engine.
Through the technical scheme of this embodiment of application, the production of UI picture still uses gamma color space, and color space conversion carries out in 3D engine rendering pipeline, can not cause UI picture source data precision loss, has also avoided the blind accent of developer to cause the work load to increase. In addition, in the scheme, the UI picture production still uses the Gamma (Gamma) color UI picture asset manufacturing stage without changing the workflow, so that the additional workload brought to a UI designer is avoided. The method is beneficial to saving the UI making period in the linear color space and enhancing the universality of the UI assets.
