Ray Tracing of Quadratic Parametric Surface

Part of the Mathematics for Industry book series (MFI, volume 4)


Over the past decades, vast research has been done on the ray-triangle intersect test but not much attention has been paid to the ray-quadratic parametric surface intersection test. In this chapter we present two direct ray tracing methods for quadratic parametric surfaces and introduce a simple optimization technique for them.
