Abstract

The short overview of several acceleration techniques for ray tracing algorithm is presented. The aim of this paper is to show how combination of both software improvements and hardware support can help to achieve higher speed of rendering. Such simple but memory and time consuming algorithm like ray tracing is an ideal case for understanding of typical speeding up methods used in three dimensional computer graphics. Most of presented approaches thus have more general validity. Keywords computer graphics, rendering, ray tracing, speeding up, parallel algorithm. 1 Introduction The ray tracing algorithm is one of the most popular methods in computer graphics and probably everybody at least partially experienced in 3D graphics knows it. The simplicity of a ray tracing (its basic version respectively) has attracted many people to implement it with the highest possible efficiency. But still no real--time ray tracer is known to author, although research papers on software improvements a...
