Dynamics for Animation

• a.k.a. physically-based animation
• large number of d.o.f. to direct by hand
• inverse kinematics helps in a limited way
• we're all subject to the laws of physics
• physics greatly constrains our motions
• physics completely constrains the motion of passive objects
• motion capture is cheating which will work in the short term
• motion capture is not a general predictive model
• dynamics can be used to answer "what if" questions
• how do body parameters impact on its motion?
• disadvantage:  need to solve difficult control problems for active objects
• taxonomy of physically-based animation
