Difference: CPSC526ComputerAnimation (6 vs. 7)

Review : "Practical Character Physics for Animators" Contribution: - Interactive system to enhance character motions, by incorporating physical properties into a existing key frame system. - Tools to enhance realism of balistic motions. - Investigate physical accuracy of manually created animation by skilled animators.

Result Evaluation:

1. Ballistic Paths : The path is created based upon the center of mass m and a constraint. The animator has 2 ways to incorporate this into the animation, either by adjusting the timing of the motion, freezing the initial and final positions or manualy adjust the path and then retime the entire motion.

2. Angular Momentum: An iterative approximation algorithm is suggested to compute the configuration (T_o) of the character given the momentum (h) specified by the user. THe method makes use of the rigid body inertia (J), velocity (v_i), the position (x)

Reproducibility:

The paper should be reproducible to a considerable extent. All the techniques used are backed up with corresponding pseudo code/step-by-step algorithm. The variables are clearly explained in both the cases of ballistic path and angular momentum. An appendix explaining the background on the equations governing the physical properties of an animation is also provided for assistance.
