Abstract
Translucency is an attractive and important effect, but it is also a challenge to synthesize efficiently in computer graphics. In this thesis, we propose a new image filter method to render translucent objects based on geometry images. we design the image filter as a hierarchical structure, and we precompute the BSSRDF diffuse scattering term before rendering. We adopt a two-pass illumination approach, which decouples the computation of irradiance at the surface from the evaluation of scattering inside the material. we apply the algorithm on current programmable GPU and reach real-time performance for translucent object rendering.
