Abstract

The invention relates to a volume cloud rendering method and device, electronic equipment and a storage medium. The method comprises the steps: drawing at least one layer of grid model outwards from an original grid model of volume cloud according to a vertex normal vector; screening pixel points of the grid model based on the noise threshold corresponding to each layer of the grid model to obtaina drawing model; calculating illumination information corresponding to the drawing model according to the illumination parameters; and rendering the drawing model according to the illumination information to obtain a to-be-displayed volume cloud. According to the technical scheme, the shape of the volume cloud is determined based on the grid model instead of the shape of the noise map, and if theshape of the volume cloud needs to be changed, only the number of additionally drawn layers needs to be set and the noise threshold value of the pixel points needs to be screened, and the specific noise map does not need to be selected in advance; therefore, the number of times of adopting the noise map is reduced, the performance overhead of generating the volume cloud is further reduced, and the volume cloud can smoothly run on the mobile terminal equipment.

Description

technical field [0001] The present application relates to the technical field of image rendering, and in particular to a volumetric cloud rendering method, device, electronic equipment and storage medium. Background technique [0002] Volumetric clouds are an important part of outdoor scenes in games. In most real-time rendering systems for small-scale 3D scenes or scenes with viewpoints near the ground, volumetric clouds are usually drawn using Ray Marching or parallax mapping. accomplish. [0003] The Ray Marching method is to expand the ray forward with equal length, sample the 3D noise map, and superimpose the multiple sampling results to generate a volume cloud. [0004] The parallax map method uses a height map to calculate the sampling position where the pixel should be offset, thereby deceiving the human eye and creating a sense of volume. [0005] The characteristic of the Ray Marching method is that the effect is very real, but it comes with a very high performan...
