Spatial deformation transfer

Mirela Ben-Chen, Ofir Weber, Craig Gotsman
2009 Proceedings of the 2009 ACM SIGGRAPH/Eurographics Symposium on Computer Animation - SCA '09  
Deformation transfer simplifies this process by allowing to infer deformations of a new shape from existing deformations of a similar shape.  ...  We propose a novel deformation transfer method, which can be applied to a variety of shape representations -tet-meshes, polygon soups and multiple-component meshes.  ...  In this paper we propose to combine the two ideas to facilitate spatial deformation transfer.

Controllable high-fidelity facial performance transfer

Feng Xu, Jinxiang Chai, Yilong Liu, Xin Tong
2014 ACM Transactions on Graphics  
Current methods for facial expression transfer, however, are often limited to large-scale facial deformation.  ...  The key idea of our approach is to decompose high-fidelity facial performances into high-level facial feature lines, large-scale facial deformation and fine-scale motion details and transfer them appropriately  ...  However, frame-by-frame deformation transfer often fails to preserve spatial-temporal correlation embedded in the source animation sequence.  ...

Quanta transfer in quantized space

Sydney Ernest Grimm
2020 Zenodo  
However, not only the phenomena emerge from the basic quantum fields, the law of Conservation of energy and the universal constants must have its origin from the same spatial structure.  ...  Conservation of quanta transfer The cause that is responsible for the pass on of topological deformation between the units is a property of every spatial unit.  ...  Because if unit B is deformed by the transfer of 1 quantum by unit A during 1 t (0→1), unit B has to deform unit C synchronously.  ...
