Real-time variable rigidity texture mapping

Conference Proceeding
Koniaris, C., Mitchell, K., & Cosker, D. (2015)
Real-time variable rigidity texture mapping. In CVMP '15 Proceedings of the 12th European Conference on Visual Media Production. https://doi.org/10.1145/2824840.2824850
Parameterisation of models is typically generated for a single pose, the rest pose. When a model deforms, its parameterisation characteristics change, leading to distortions i...
