Real-time variable rigidity texture mapping

Charalampos Koniaris, Kenny Mitchell, Darren Cosker
2015 Proceedings of the 12th European Conference on Visual Media Production - CVMP '15  
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".  ...  We demonstrate the usefulness of our method in a variety of scenarios: from application to production-quality assets, to realtime modelling previews and digital acting.  ...  Acknowledgements We would like to thank Malgorzata Kosek for textures and the Blowfish and MugJug models, Martin Klaudiny for the face model, Stephen Grabli and Jose A.  ...
