Realtime shape-enhanced shading of large scale skinned meshes with fast normal updating

Shape exaggeration is highly expected in many applications such as cultural heritage, cartography, educational demos, game etc. Although there have been some research on shape-exaggerated shading, most of them are too slow for real-time applications when large scale meshes are involved. We notice the bottleneck is updating of surface normal. Based on this observation, we present a real-time shape-exaggerated shading method for large scale skinned meshes. The key component is a fast normal updating method tailored for skinned meshes. Experimental results show that our method can generate shading results that are comparable to existing methods in real-time.
