Ray tracing surfaces of revolution: An old problem with a new perspective
February 2001Proceedings of Computer Graphics International Conference, CGI
Abstract
We present a new subdivision scheme that is shown to improve the performance of
ray tracing surfaces of revolution over Kajiya's (1983) classical work. This is
based on a monotonic interval partitioning of a generatrix of a surface of
revolution. The algorithm has a search complexity upper bound of O(log(m n)) for
m monotonic intervals and n subdivisions for each interval and runs up to three
times faster on large scenes. This method also suggests a novel hybrid bounding
volume scheme that reduces this number of intersection tests between a ray and
the actual object surface
