Abstract

This paper presents an algorithm for animation in global illumination environment for dynamic scenes illuminated by arbitrary, static light sources. Global illumination techniques are difficult to apply for the generation of photorealistic animations because of their high computational costs. These costs are so huge that they take many weeks of computation even on expensive rendering farms, using traditional frame-by-frame rendering systems. Reducing high computational and time costs is of significant practical importance.
