Real-time Rendering of Heterogeneous Translucent Objects using Voxel Number Map

Eurographics 2016

Abstract:
Rendering of tranlucent objects enhances the reality of computer graphics, however, it is still computationally expensive Download Patternmaker. In this paper, we introduce a real-time rendering technique for heterogeneous translucent objects that contain complex structure inside.
 First, for the precomputation, we convert mesh models into voxels and generate Look-Up-Table in which the optical thickness between two surface voxels is stored 제 5인격. Second, we compute radiance in real-time using the precomputed optical thickness. At this time, we generate Voxel-Number-Map to fetch the texel value of the Look-Up-Table in GPU 피스메이커. Using Look-Up-Table and Voxel-Number-Map, our method can render translucent objects with cavities and different media inside in real-time.
