Volume fog generation method and device, electronic equipment and storage medium

Abstract

The invention provides a volume fog generation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring scene depth information and terrain information; setting a volumetric fog area; determining information of a bounding box according to the scene depth information and the volume fog area; and generating volume fog according to the topographic information and the information of the bounding box. Therefore, the volume fog and scene interaction problem is solved, the volume fog is generated in combination with the scene, the concentration and form diversification in the volume fog are achieved, different areas can be adjusted according to the depth information of the scene, the rendering effect is better and more real, the immersion in the virtual scene is improved, and the user experience is improved. And additional scattering part and dark part highlight calculation are added on fog effect rendering, so that the scattering effect of the volume fog is enhanced, and the problem that the volume fog of the projection shadow part has no effect is solved through self-luminous superposition of the same effect.

Description

technical field [0001] The present application relates to the technical field of computer images, and in particular to a volumetric fog generation method, device, electronic equipment and storage medium. Background technique [0002] In order to pursue the sense of immersion in the virtual scene, volumetric fog can be introduced into the virtual scene. In related technologies, the UE4 engine is often used to generate fog effects based on the range of the bounding box. In the Unreal 4 engine, the material editor is used to create through node connections. The material uses noise to shape the shape of the volumetric fog, uses the RayMarch volumetric algorithm to render the volumetric fog, and introduces it into the virtual scene. [0003] However, the related technology is only a simple model-based bounding box rendering. The rendered effect is relatively rigid in the virtual scene, and the concentration and shape inside the volumetric fog are single, which is not conducive to...

Problems solved by technology

[0003] However, the related technology is only a simple model-based bounding box rendering. The rendered effect is relatively dull in the virtual scene. The concentration and shape inside the volumetric fog are single, which is not conducive to adjustment according to different regions.
