Abstrakt v dalším jazyce:	In a process of the radiosity computation, the most demanding part is to evaluate a form factor (FF). Therefore, a lot of investigation has been done in order to speed up the part while preserving accuracy of the result. One of the first methods used for the form factor evaluation was the hemicube (HC) approach. Nevertheless, the original HC method still consumes too much time and memory, so that high resolution could be afforded only on really powerful hardware. In this paper we show, how can this method be used for fast and accurate form factor computation. We have implemented and compared several variants of the original scheme and propose a new algorithm which drastically reduce memory requirements of FF evaluation.
