Hair When discuss in g the pr actical algorithm for simulatin g the dynamic beh av-
ior of cloth , it was suggested the relaxation-Vertlet algorith m could be adapted
to simulate the movement of hair. Thought of as a rigid chain of small segments
attached at one end (at the root of the hair) and free at the other, each segment
carries a small mass that is subjected to inertial and gravitational for ces . As the
root is moved, the rest of the hair follows with its motion determined us in g an
algorithm similar to that used for cloth in listing 6.7. To be realistic it will be
necessary to build th e model with many hundreds
