GPU Based Evaluation and LOD Rendering of NURBS Surfaces

Abstract

This paper proposes a new GPU method for the evaluation and LOD (Level of Detail) rendering of NURBS surfaces. Compared with the existing evaluation method of basis function, the approach simplifies the process by just one-pass and saves the graphics memory with only one texture array. The wavelet based LOD rendering method also saves the time to re-evaluate and re-transfer the data for rendering.
