Abstract:
1. A method of animating an object, the method comprising: receiving information identifying a plurality of animation variables that are coupled; receiving a first set of knots defined for one or more animation variables in the plurality of animation variables, each knot for an animation variable in the first set of knots identifying a time point and a value for the animation variable at that time point; and generating a second set of knots for the plurality of animation variables based upon the first set of knots; for at least one animation variable in the plurality of animation variables, generating, based upon the first set of knots and the second set of knots, a value for the at least one animation variable at a time point at which no knot exists for the at least one animation variable in the first set of knots or the second set of knots; rendering the object on an output device using the plurality of animation variables; generating a path based upon the first set of knots and the second set of knots; and generating a timing spline for the path, the timing spline comprising a knot for each control-point in the set of control-points, each knot of the timing spline identifying a time point and an indication of distance traveled along the path at that time point.
