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 threedimensional raysurface intersection problem into a twodimensional raycurve intersection problem, which is solved by the method of strip trees. The surface ofrevolution algorithm transforms the threedimensional raysurface intersection problem into a twodimensional curvecurve intersection problem, which again is solved by strip trees.
