Title: Efficient visibility calculation for light transport simulation in participating media Author: Čestmír Houška Department / Institute: Department of Software and Computer Science Educa- tion Supervisor of the master thesis: doc. Ing. Jaroslav Křivánek, Ph.D. Abstract: This thesis investigates the use of acceleration methods for the testing of visibility in light transport calculation algorithms with the emphasis on conser- vativeness and low accelerated query overhead. Several published non-directional and directional distance field methods are presented with the description of their characteristic properties. Two of these methods are then implemented and thor- oughly tested in an existing rendering framework on a path tracing volumetric integrator as well as on an own implementation of a ray marching single scattering integrator. A method that further accelerates the original distance field methods by pre-caching results of some of the queries is also proposed, implemented and tested. Furthermore, several possible extensions to this method are outlined. Keywords: computer graphics, rendering, participating media, visibility
