- In case anyone is curious about what an "animated heirarchical
- free-form deformation lattice" is:
-
- It gives the user the ability to define a lattice of points that
- serve as a "duct-works" that the object or heirarchy of objects
- travels through. Imagine that you wish to model the path that a piece
- of paper takes on it's journey through a photocopy machine. If you
- try to create morph targets for each bend in a system that only offers
- morphing, you would find that the paper would start to bend before
- it reached the bend. To compensate you would have to create more
- targets. Ultimatly, you would have to create as many targets as frames
- in the animation. In the AFFD system, a "tube" would be built, and this
- tube would be bent into the shape of the desired path. The object/s
- bend/stretch/squash to follow the shape of the tube.
-
- It's an incredible technique, and one that most of the very high-end
- packages lack. I first became aware of the method at this last SIGGRAPH.
