GPU-Based Adaptive-Subdivision for View-Dependent Rendering

Abstract

In this paper, we present a novel view-dependent rendering approach for large polygonal models. In an offline stage, the input model is simplified to reach a light coarse representation. Each simplified face is then assigned a displacement map, which resembles the geometry of the corresponding patch on the input model. At runtime, the coarse representation is transmitted to the graphics hardware at each frame. Within the graphics hardware, the GPU subdivides each face with respect to the viewparameters, and adds fine details using the assigned displacement map. Initial results show that our implementation achieves quality images at high frame rates.
