Real-time Rendering of Deformable Translucent Objects

Abstract

This paper introduces an efficient real-time shading model to simulate light transport in translucent materials. In this work no pre-processing step is needed, allowing us to deform translucent objects at interactive rates. The proposed technique avoids the pre-processing of texture atlas and texture coordinates that may entail distortions and self-occlusion errors. We create a cube map texture atlas on the GPU by a specific projection providing accurate access to neighborhood information is accurate. The texture atlas is generated on-the-fly each time the mesh geometry is modified, allowing us to deform the object geometry in real time keeping valid the subsurface light transport computation.
