Abstract: This paper introduces a new method-volumetric radiosity method, which can be used to generate virtual reality images. Based on the emission, absorption, diffusion, reflection and scatteration of light by a voxel, it is suitable for generating and rendering realistic images of complex scenes. In this paper, the basic principle of volumetric radiosity is briefly introduced. It covers intensity calculation, radiosity equations, form factors and image generation method.
