Real-time Variable Rigidity Texture Mapping-Image

Parameterisation of models is typically generated for a single pose, the rest pose. When a model deforms, its parameterisation characteristics change, leading to distortions in the appearance of texture-mapped mesostructure. Such distortions are undesirable when the represented surface detail is heterogeneous in terms of elasticity (e.g. texture with skin and bone) as the material looks “rubbery”. In this paper, we introduce a technique that preserves the appearance of heterogeneous elasticity textures mapped on deforming surfaces by calculating dense, content-aware parameterisation warps in real-time. We demonstrate the usefulness of our method in a variety of scenarios: from application to production-quality assets to real-time modeling previews and digital acting.
