Abstract
A system and method for intuitively generating computer-assisted animation utilizes a transformation space in which a computer input device such as a three-dimensional drawing wand is moved to generated constructed poses from a plurality of source poses. The transformation space may be in the form of a tetrahedron with each of the four vertices representative of a source pose. At any point within the three-dimensional volume of the tetrahedron, a constructed pose may be defined based on weighted averages of the four source poses. The animator may create a sequence of animation simply by moving the drawing wand within the tetrahedron. The rate of change of the transformations of the constructed poses is controlled by the rate of movement of the drawing wand but may be altered after the sequence of constructed poses is defined.
