  abstract={Realistic rendering algorithms such as ray tracing
are computationally very expensive. The time complexity is determined
by a multitude of factors such as image size, geometry, material properties
and the quality of the required rendering. This paper presents an algorithm
to estimate the cost of ray tracing a scene. Assuming an octree spatial
subdivision, the cost per voxel is predicted. For parallel processing
purposes, this cost distribution can then be used to calculate an initial
data distribution, such that the workload per processor should be more
or less equal. The method avoids intersection tests, because those
may affect the short response times required for preprocessing stages.},
