A good keyframe animation computer system
limits the number of key parameters and maximizes the utility of each.
- Parameters should have immediate
geometric or visible significance.
Entries in a transformation matrix are not good parameters.
- Properties of objects that are static should be maintained
- Relationships between parts of articulated objects should be
- Interpolation routines should be optimized to particular
parameter types. Motion paths, orientation, camera attitude, and
surface properties all require different types of control.
A real-time interface should be provided
to interactively set parameters and iteratively improve the animation.
