Synthesis of human and animal skin deformation [thesis]

Zheng Guo
To synthesize skin deformations for an articulated character, the skin of the character is decomposed into patches and the deformation of every patch is created individually. Using this strategy of decomposition, two skin deformation methods are proposed: Example Based Transferable Layered Enveloping (EBTLE) and Skinning With Deformable Chunks (SWDC). EBTLE uses the skeleton to deform the skin through a base control mesh, which is derived from the patch structure of the skin. Based on radial

Furthermore, using the base control mesh as a common platform, with the parameterizations of the skin patches, EBTLE can use the examples of one character to guide the skin deformations of other geometrically similar characters. The experiments have shown that EBTLE can generate aesthetically pleasing results at interactive speed.
