Abstract
Animating strands (such as long hair), for movies, videos, etc. is accomplished using computer graphics by use of differential algebraic equations. Each strand is subject to simulation by defining its motion path, then evaluating dynamic forces acting on the strand. Collision detection with any objects is performed, and collision response forces are evaluated. Then for each frame a differential algebraic equations solver is invoked to simulate the strands.
