Per-Pixel Evaluation of Parametric Surfaces on GPU

In this paper, we propose a per-pixel evaluation method of parametric surfaces using GPU which is effective for rendering. For the evaluation of surfaces on GPU, [Bolz and Schröder 2003] have proposed a method for rendering subdivision surfaces. Unfortunately, the final rendering is done by subdivided polygons in this approach. The characteristic of our scheme is to perform the evaluation in the fragment program from parameters of each fragment. This ensures a (at least pixel-based) high quality surface rendering. We also introduce an example of using our per-pixel surface rendering scheme.
