ABSTRACT:
A computer-implemented method and apparatus for animating a property (such as the position of an object) using floating keyframes to selectively decouple property space and time constraints. Fixed keyframes and floating keyframes may used to specify a path through an n-dimensional property space, but the motion along the path is controlled only by the fixed keyframes. The timing of the floating keyframes is determined by temporal attributes of the nearest fixed keyframes.
