Abstract

The invention provides a cloud layer rendering method and device, equipment and a storage medium, and the method comprises the steps: determining a current illumination direction in a virtual scene, obtaining the light path information of a to-be-rendered cloud layer corresponding to the current illumination direction,wherein the light path information isdetermined by the RGBA channel position parameters of a texture map of the to-be-rendered cloud layer, and coloring the to-be-rendered cloud layer according to the light path information. The cloud layer rendering method provided by the invention is not high in equipment performance requirement, reduces the performance overhead of the equipment, and increases the visual expressive force of the cloud layer.

Description

technical field

[0001] The present application relates to the technical field of image processing, and in particular, to a cloud layer rendering method, apparatus, device, and storage medium. Background technique

[0002] With the rapid development of game production technology, the pictures presented in the game are becoming more and more realistic. Among them, the sky is an indispensable element in most games. The sky can be divided into background atmosphere and clouds. The performance of the atmosphere and clouds at different times and under different weather conditions forms a colorful sky with strong visual expression.

[0003] In the prior art, in order to render a realistic cloud layer effect, ray stepping (English: Raymarch) is often used to sample 3D texture maps to obtain the basic shape of the cloud layer, and then a physics-based lighting algorithm is used to calculate the lighting of the cloud layer, so that the Create dynamic, expressive cloud effects at diff...
