Illumination calculation method and device, computer equipment and computer readable storage medium

Abstract

The invention discloses an illumination calculation method and device, computer equipment and a computer readable storage medium, and relates to the technical field of image processing. A view cone of a target scene is divided to obtain a plurality of polyhedrons, light source lists are generated by judging the relative relation between the polyhedrons and light sources, the light source list corresponding to the polyhedron where a fragment is located is used for calculation, and the cut light source is used for illumination calculation of the fragment, so that the calculation amount is reduced, the possibility of serious performance problems in a complex scene is greatly reduced, and the bandwidth pressure is relieved. The method comprises the following steps: dividing a view cone of a target scene in a preset dimension to obtain a plurality of polyhedrons; determining a relative relationship between the plurality of polyhedrons and a plurality of light sources in the target scene, and generating a plurality of light source lists according to a determination result; determining a target fragment, and querying a target polyhedron to which the target fragment belongs in the plurality of polyhedrons; and performing illumination calculation on the target fragment based on the target light source list corresponding to the target polyhedron.

Description

Technical field [0001] The present application relates to the field of image processing, and in particular, to a light-sensitive method, a device, a computer device, and a computer readable storage medium. Background technique [0002] In recent years, image processing technology has been continuously developed. Whether it is user or developers, the requirements for image quality are getting higher and higher, in order to improve the quality of computer animations, enhance their true sense, environment-based lighting for illumination and light rendering It has become a key point in image processing. [0003] In the relevant technique, in the light rendering, the forward rendering is usually carried out. The forward rendering is also called forward rendering. It is a direct way of rendering objects. In traditional forward rendering, first, determine all of the objects that need to be rendered in the scene, and select any object. Subsequently, the selected object is intersected wit...
