Real-time variable rigidity texture mapping (2015)
Presentation / Conference Contribution
Koniaris, C., Mitchell, K., & Cosker, D. (2015, November). Real-time variable rigidity texture mapping. Presented at Proceedings of the 12th European Conference on Visual Media Production - CVMP '15

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 unde...
