HMorphAnimClass
|
||||
|
||||
This is an animation format designed for facial animation. It basically morphs the
|
||||
htree between a set of poses. These animations are created by exporting an
|
||||
HRawAnimClass which contains the poses, using Magpie to create a text file
|
||||
describing which pose to use on each frame, and finally using W3dView to combine
|
||||
the data into an HMorphAnimClass.
|
||||
|
||||
There can be multiple channels for the morphing. For example, some of the
|
||||
bones can be controlled by the "phoneme" poses (e.g. mouth) while other bones are
|
||||
controlled by the "expression" poses (e.g. eyebrows)
