Abstract

The invention discloses a method and a device for simulating global illumination in a scene. The method comprises the steps that a three-dimensional scene space is simulated to be formed by a plurality of continuous spatial polyhedrons; for each vertex of the spatial polyhedrons, a camera is respectively simulated to face toward the vertex to perform image capturing on the three-dimensional scene space in multiple preset directions taking the vertex as a benchmark, and multiple scene images simulated in the multiple preset directions are acquired; ambient light color information of the vertex in the preset directions is determined according to pixel colors of each pixel in the scene images simulated in the preset directions; the acquired ambient light color information of each vertex of each spatial polyhedron in the different preset directions is stored to be global illumination parameters of the three-dimensional scene space. The method and device disclosed by the invention can improve the accuracy of ambient light information of different spatial position points in the built scene, thereby being conducive to reflecting global illumination effects of a dynamic object more authentically.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for simulating global illumination in a scene. Background technique [0002] Global illumination is a very important research field in computer graphics. By simulating the lighting conditions in nature, it captures the lighting effects such as soft shadow and indirect refraction produced by the multiple propagation of light in the real environment (such as refraction and reflection). , these effects can greatly enhance the realism of the rendering results. At present, global illumination has been widely used in animation, virtual reality, games and other fields. [0003] In the fields of animation, virtual reality or games, in addition to static objects (objects or characters fixed in the scene, etc.), the scene will also contain a large number of dynamic objects (objects or characters that can move in the scene) Wait). For static obj...
