Embodiment Construction

[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0020] In the development of virtual scenes, Volumetric Fog is usually used to simulate fog or clouds in real scenes. However, the existing methods for rendering volumetric fog consume too much computing resources, and when it is necessary to render volumetric fog with richer details, the operating efficiency of the rendering system will be greatly hi...

Abstract

The embodiment of the invention provides a volume fog rendering method and device, equipment and a storage medium. Wherein when the volume fog is rendered, the rendering texture of the current frame is drawn by adopting a down-sampling resolution ratio, and when the light stepping is carried out, the stepping starting point of the current frame is shifted; and carrying out illumination calculation by adopting the shifted light stepping point to obtain the volume fog rendering texture of the current frame, and mixing the volume fog rendering texture of the current frame with the volume fog rendering texture of the historical frame to obtain the updated volume fog rendering texture of the current frame. Based on the implementation mode, the rendering overhead of each frame can be reduced through a mode of performing downsampling on each frame, and missing pixels in the current frame are supplemented through a mode of performing multi-frame rendering texture mixing on the current frame and the historical frame, so that the rendering overhead can be reduced under the condition of ensuring that the rendered volume fog has relatively high pixel precision, and the rendering efficiency of the volume fog is improved. And the rendering fluency is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a volumetric fog rendering method, device, equipment and storage medium. Background technique [0002] In the development of virtual scenes, Volumetric Fog is usually used to simulate fog or clouds in real scenes. However, the existing methods for rendering volumetric fog consume too much computing resources, and a new solution needs to be proposed. Contents of the invention [0003] Various aspects of the present application provide a volumetric fog rendering method, device, device, and storage medium to reduce the rendering overhead of volumetric fog. [0004] An embodiment of the present application provides a volumetric fog rendering method, including: drawing a cube model in the current frame of the target scene according to the downsampled resolution of the target scene; the cube model is used to represent the volumetric fog in the target scene Co...
