In this paper, we present a local motion planning algorithm for character animation. We focus on motion planning between
two distant postures where linear interpolation leads to penetrations. Our framework has two stages. The motion planning problem is
first solved as a Boundary Value Problem (BVP) on an energy graph which encodes penetrations, motion smoothness and user control.
Having established a mapping from the configuration space to the energy graph, a fast and robust local motion planning algorithm is
introduced to solve the BVP to generate motions that could only previously be computed by global planning methods. In the second
stage, a projection of the solution motion onto a constraint manifold is proposed for more user control. Our method can be integrated
into current keyframing techniques. It also has potential applications in motion planning problems in robotics.
