The invention relates to an illumination determination method for a volume cloud in a virtual environment, related equipment and a storage medium. The method comprises the following steps of: determining a theoretical illumination value of any pixel of a volume cloud in a current frame of virtual image; determining occlusion change information of the current frame of virtual image relative to N frames of images before the current frame of virtual image in any pixel; determining a mixing coefficient corresponding to any pixel according to the occlusion change information of the current frame of virtual image relative to N frames of images before the current frame of virtual image in any pixel; and according to the mixing coefficient, mixing the illumination value of any pixel in the Nth frame of image and the theoretical illumination value to obtain the illumination value of any pixel in the current frame of virtual image. The method and the device are used for solving the problem that when a moving object exists in a volume cloud area in a virtual scene, the concentration after volume cloud rendering is affected by the moving object, and deviation exists between the volume cloud and a simulated real scene.
Description
technical field [0001] The present application relates to the field of virtual reality technology, and in particular to a method for determining illumination of volumetric clouds in a virtual environment, related equipment and storage media. Background technique [0002] Volumetric Clouds, generally called volumetric clouds or volumetric fog, volumetric clouds in virtual reality scenes such as games use image engines to simulate the translucent and irregular performance of real clouds and fog. [0003] Ray Marching (English name: Ray Marching) is a commonly used technique for rendering light in the process of making volumetric clouds or volumetric fog, and is used for fast rendering of real-time scenes. The main rendering idea is: simulate the camera position, according to the expansion angle of the viewing frustum, take the camera position as the origin, and emit rays step by step. When the ray hits the object, return its depth information. If the maximum distance to the vi...
