Abstract
We present an algorithm for ray tracing implicit surfaces.
The algorithm first divides space uniformly and areas of interest are adaptively
subdivided using an octree method. We review earlier work on
reducing intersection calculations in ray tracing and introduce a new
data structure, a variation on the octree, that is more efficient in
both time and memory requirements. Our results indicate that using this
hybrid algorithm retains the benefits of both uniform and octree subdivision
while providing better average performance than using either one of these
approaches alone.
