significant advantage of ray tracing is that it can directly handle a wide range of geometric primitives including free-form primitives such as splines and subdivision surfaces. However, all...

ing algorithms for ray tracing free-form surfaces are much too slow for interactive use. In this paper we present a simple and generic approach for ray tracing free-form surfaces together with specific implementations for cubic Bézier and Loop subdivision surfaces. We show that our approach allows to increase the performance by more than an or-

Directly handling free-form surfaces such as spline or subdivision surfaces instead of first tesselating them offers many advantages such as higher precision results, reduced memory requirements, and faster preprocessing due to less primitives. However, existing algorithms for ray tracing free-form surfaces are much too slow for interactive use.

In this paper we present a simple and generic approach for ray tracing free-form surfaces together with specific implementations for cubic B\'ezier and Loop subdivision surfaces. We show that our approach allows to increase the performance by more than an order of magnitude, requires only constant memory, and is largely independent on the total number of free-form …
