Abstract:
In animation, hair styles can often be modeled without the consideration of physics. One of the side effects of this workflow is that external forces such as gravity will deform the groom from the designed shape when simulated. We present a simple optimization algorithm that preloads the rest shape to compensate for the external forces to maintain the groom shape during simulation. The algorithm provides artistic control over how much force is compensated for at each vertex.
