Sample Questions

  1. In computing the impulse force of a collision, what 4 components are there in computing the relative velocity of the points involved in the collision?
  2. Discuss the forces that are used in controlling the motion of a member in a flock?
  3. Describe explicit Euler integration. What is the underlying assumption being used with regard to integrating acceleration to produce a new velocity at the end of a time step? This assumption is wrong in the case of time-varying forces such as that found in simulating a spring.
  4. What is the Frenet Frame? Describe considerations of its continuity.
  5. In the motion capture process, What is involved in 'cleaning the data'?
  6. Describe the use of the transpose of the Jacobian In inverse kinematics.
  7. What are the tradeoffs between using quaternions and using Euler angles to represent object orientation.
  8. In behavior animation, what are the different types of 'vision' that can be computed for a character?
  9. Given a rod attached at one end to a wall by a hinge joint, what does the force of gravity do to the rod - describe the situation in terms of forces and torques.
  10. In collision response, what is the 'penalty method'?
  11. How does the CCD method of IK differ from the method that uses the transpose of the Jacobian - consider the configuration draws on the board.
  12. Discuss the problem of tracking markers in mocap. What is the main advantage of active optical mocap as opposed to passive optical mocap with respect to tracking markers
