Patent ID: 7129950

Claim:
A method for improving visual depiction of animation splines in a computer assisted animation system, the method comprising: producing a source spline formed of paths between a sequence of knots to define a path between a first end knot and a second end knot; displaying the source spline on a computer display monitor of the computer assisted animation system wherein first axes represent time and second axes represent distance; analyzing the source spline to designate pose knots and timing knots between the first and second end knots, wherein at least one timing knot is established between successive pose knots; thereafter producing a flipped spline wherein second axes through the pose knots are reversed; displaying the flipped spline on the computer display monitor as a sawtooth spline display for evaluation and to allow adjustment of the source spline; adjusting the source spline to adjust a trajectory of the source spline between the first end knots and the second end knot; and using the source spline to produce an animation sequence.
