Abstract
An aspect provides a computer-implemented method for generating an animation control rig configured to manipulate a skeleton of an animated character. The method comprises associatinga plurality of animation control points to an animated skeleton; traversing () a node graph representing the plurality of animation control points of the animated skeleton; analyzingthe hierarchical node graph to determine which nodes of the hierarchical node graph are inversely solvable; analyzingthe hierarchical node graph to determine which other nodes of the hierarchical node graph are solvable with at least one solution that violates a constraint of the animated skeleton; and modifyingan operation of at least one node of the other nodes that violates a constraint to approximate the constraint within a tolerance level.
