Deformation and Animation
Vertex deformation is a popular technique to animate an object using a controlling stick-figure skeleton. Previously, however, it has been difficult to deform those vertices near multiple limbs of the skeleton while maintaining a natural-appearing surface.By applying convolution to the medial axis/surface of the object, the weights associated with vertex deformation can be computed automatically. Fewer undesired artifacts are evident in the animated surface.
