Embodiment Construction

[0108]In order to make the purpose, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be described clearly and completely in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments These are a part of the embodiments of this application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0109]Volumetric Clouds (Volumetric Clouds) are generally called volumetric clouds. Volumetric clouds in the game use an image engine to simulate the translucent and irregular performance effects of real clouds.

[0110]At present, with the development of mobile games, taking into account the performance limitations of mobile terminals such as mobile phones, it is necessary for m...

Abstract

The present application relates to a volume cloud rendering method, device, electronic equipment and storage medium, the method comprising: drawing the original grid model of the volume cloud according to the vertex normal vector to draw at least one layer of grid model; The noise threshold corresponding to the grid model screens the pixels of the grid model to obtain a rendering model; calculates the illumination information corresponding to the rendering model according to the illumination parameters; renders the rendering model according to the illumination information to obtain Volumetric cloud to be displayed. The shape of the volumetric cloud in this technical solution is determined based on the grid model, rather than the shape of the noise map. If you want to change the shape of the volumetric cloud, you only need to set the number of additional layers drawn and the noise threshold for filtering pixels. , there is no need to pre-select a specific noise map; reducing the number of noise maps used further reduces the performance overhead of generating volumetric clouds, making volumetric clouds run smoothly on mobile devices.

Description

Technical field[0001]This application relates to the field of image rendering technology, and in particular to a volume cloud rendering method, device, electronic equipment and storage medium.Background technique[0002]Volumetric clouds are an important part of outdoor game scenes. In most small-scale 3D scenes or real-time rendering systems for scenes with viewpoints located near the ground, volumetric clouds are usually drawn by Ray Marching or parallax mapping. achieve.[0003]The Ray Marching method is to expand the ray equal length forward, sample the 3D noise map, and superimpose the results of multiple samples to generate volume clouds.[0004]The parallax mapping method uses a height map to calculate the sampling position of the pixel point that should be offset, and then deceives the human eyes and produces a sense of volume.[0005]The characteristic of the Ray Marching method is that the effect is very real, but the performance overhead is very high. It is necessary to calculate...
