Zobrazování vlasů a srsti metodou sledování paprsků

Abstract

This thesis deals with ray-tracing hair and fur. At the beginning of this thesis, the development of algorithms in given area is chronologically captured. The following describes the three current techniques addressing this issue. A detailed analysis of one of these current methods follows. The chosen method is able to determine the ray-curve intersection without using its approximation by polygons where it is not clear how to determine an appropriate tessellation rate. This approach is advantageous because it always ensures a smooth fibers rendering. The second part of the text focuses on the implementation of selected method and evaluation of results.
