Abstract

The invention discloses a calculation method and device for global illumination. The method comprises the following steps that: obtaining directed distance field information and/ or illumination information corresponding to each pixel in a plurality of preselected pixels in a screen, wherein the directed distance field information and/ or illumination information corresponding to each pixel is stored in a two-dimensional map mapped from a three-dimensional map; and according to the directed distance field information and/ or illumination information corresponding to each pixel, carrying out global illumination calculation. By use of the method, the technical problem that a calculation method for the global illumination in the relevant art consumes more hardware resources and a presented picture effect is not ideal can be solved.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a calculation method and device for global illumination. Background technique [0002] At present, global illumination has always been a hot spot in real-time game rendering. The rendered picture not only needs to consider the effect of the light emitted by the scene light source directly irradiating the surface under consideration (that is, the surface of the object), but also needs to consider the light from the light source reflected by other surfaces. Then hit to consider the lighting effect of the surface. Global illumination plays a huge role in the blending of object lighting realism and surrounding environment. In order to solve the global rendering equation, the global illumination requires multiple iterative integration, but there is no analytical solution, so only the integration method related to Monte Carlo can be used to obtain the numerical solution. Cons...
