Re: Cardinal shape interpolation when blending weights between shape clips

[Bradley Gabe <withanar(at)stanwinston.com>]

If you have all the points on an area of the face travel from shapeA to shapeB, it doesn't matter if their path is linear from a standard weight blend, or curved from a cardinal interpolation, all the points move from pose to pose, they start at the same time and they stop at the same time. It ends up looking like a morph.

This is okay for some situations and some kinds of motion, but almost never for natural looking facial animation or flesh effects. What we see on the surface of the skin is obviously the result of many compound motions, so we need our animation to reflect many compound motions and not the pose to pose nature of shape animation.
