Customized rendering method of volumetric cloud, equipment and storage medium

Abstract

The embodiment of the invention provides a customized rendering method of volumetric clouds, equipment and a storage medium. According to the method, when a custom-designed volumetric cloud is rendered in a target scene, a model of the volumetric cloud can be obtained; signed distance field information of the target scene is calculated according to the model of the volumetric cloud and a position of the volumetric cloud in the target scene, wherein the signed distance field information includes a minimum distance of a point in the target scene to a surface of the volumetric cloud; and the signed distance field information of the target scene can be used as a rendering resource file of the target scene, so that the volumetric cloud can be rendered based on the signed distance field information of the target scene when the target scene is rendered. In the implementation mode, a shape of the cloud in the target scene can be specified based on the model of the volumetric cloud and the signed distance field information, and the cloud with the specified shape is rendered, so that customized rendering requirements of the volumetric cloud are met; and meanwhile, modeling of the volumetric cloud and modeling of the target scene can be independently carried out, so that the modeling efficiency of a virtual three-dimensional space can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a customized rendering method, device and storage medium for volumetric clouds. Background technique [0002] Volumetric Cloud (Volumetric Cloud) can also be called volumetric cloud or volumetric fog. When rendering virtual scenes (such as game scenes), image engines are usually used to simulate the translucent and irregular performance of real clouds and fog. However, in the existing volumetric cloud rendering methods, the volumetric cloud is usually obtained based on the superposition of noise maps, and the cloud of a specified shape cannot be rendered. Therefore, a solution remains to be proposed. Contents of the invention [0003] Various aspects of the present application provide a customized rendering method, device, and storage medium for volumetric clouds, which are used to flexibly render volumetric clouds according to a customized volumetric cl...
