1. A computer-implemented method of rendering an object present in a scene, wherein rendering is part of animation and animating comprises determining a visual presentation of the object in the scene over a plurality of animation frames, the method comprising:
receiving information identifying a plurality of position and orientation animation variables that are coupled; receiving a first set of knots defined for one or more animation variables in the plurality of position and orientation animation variables, each knot for an animation variable identifying a time point and a value for the animation variable at that time point, the first set of knots corresponding to a first subset of a set of data points, wherein the first set of knots includes a first knot that identifies a first time point and a first value of a first animation variable; generating a second set of knots for the plurality of position and orientation animation variables, the second set of knots including a second knot defined for a second animation variable at the first time point, wherein the value for the second knot for the second animation variable is determined based on the first value of the first knot at the first time point, the second set of knots corresponding to a second subset of the set of data points; for at least one animation variable in the plurality of position and orientation 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 using the plurality of position and orientation animation variables and the at least one animation variable; and storing the rendered object to a non-transitory computer readable medium. |
