Figure 1: Rendering of the Frog model (left), using feature-adaptive subdivision [Nießner et al. 2012a] takes 0.68ms (middle); our method only takes 0.36ms by performing locally adaptive subdivision (right); colors denote different subdivision levels. AbstractFeature-adaptive subdivision (FAS) is one of the state-of-the art real-time rendering methods for subdivision surfaces on modern GPUs. It enables efficient and accurate rendering of subdivision surfaces in many interactive applications, such as video games or authoring tools. In this paper, we present dynamic feature-adaptive subdivision (DFAS), which improves upon FAS by enabling an independent subdivision depth for every irregularity. Our subdivision kernels fill a dynamic patch buffer on-the-fly with the appropriate number of patches corresponding to the chosen levelof-detail scheme. By reducing the number of generated and processed patches, DFAS significantly improves upon the performance of static FAS.
