Abstract
In this paper we present a method for interactive rendering general procedurally defined functionally represented
(FRep) objects using the acceleration with graphics hardware, namely Graphics Processing Units (GPU). We
obtain interactive rates by using GPU acceleration for all computations in rendering algorithm, such as raysurface
intersection, function evaluation and normal computations. We compute primary rays as well as
secondary rays for shadows, reflection and refraction for obtaining high quality of the output visualization and
further extension to ray-tracing of FRep objects. The algorithm is well-suited for modern GPUs and provides
acceptable interactive rates with good quality of the results. A wide range of objects can be rendered including
traditional skeletal implicit surfaces, constructive solids, and purely procedural objects such as 3D fractals.
