Synergetic CG Choreography through Constraining and Deconstraining at Will

This paper presents an interface for creating whole body motions of human and animal characters without reference motion Its basic function is to enable an imators to generate a natural motion by dragging a link to an arbitrary position with any number of links pinned in the global frame as well as other constraints such as desired joint angles and joint motion ranges Each constraint can be switched on or o strength ened or weakened for each joint at a user s will The interface is based on a new online inverse kinematics technique that allows more exible attachment of pins and various types of constraints Editing or retarget ing captured motion requires only a small modi cation to the original method although the method can create natural motions from scratch We also demonstrate the power and usability of the proposed method by a number of example motion clips
