summary |
We present new algorithms for efficient ray tracing of three procedurally defined objects: fractal surfaces, prisms, and surfaces of revolution. The fractal surface algorithm performs recursive subdi- vision adaptively. Subsurfaces which cannot intersect a given ray are culled from further consideration. The prism algorithm transforms the three-dimensional ray-surface intersection problem into a two-dimensional ray-curve intersection problem, which is solved by the method of strip trees. The surface- of-revolution algorithm transforms the three-dimensional ray-surface intersection problem into a two-dimensional curve-curve intersection problem, which again is solved by strip trees. |
