Podpovrchový rozptyl světla v průsvitných materiálech

Abstract

This thesis addresses the issues of subsurface scattering of translucent materials within computer image synthesis. In the theoretical section, a mathematical apparatus is introduced for describing the transport and scattering of light. The radiative transfer equation and the generalized form of the rendering equation are explained. This is followed by a detailed description of the random walk method, which is used to render translucent materials in the context of global illumination. The overview of used methods also includes the accelerating technique of diffusion approximation. The second part of the thesis describes the implementation of selected methods within a shader for the NVidia OptiX 8.0 library.
