CS 426 Exercises
  Animation

  1. What are the differences betweeen animation and simulation? Give an example of each.
  2. What type of aliasing occurs in animation that does not occur during rendering of a single image? How can we avoid such aliasing? Explain why the aliasing occurs and give pseudocode for your method to avoid it.
  3. What are the differences between kinematics and dynamics? Give an example of how an animator would use each. Which did you use in assn 5?
  4. What are the differences between forward and inverse kinematics? Give an example of how an animator would use each. Which did you use in assn 5?
  5. Why are inbetweens harder to compute with inverse kinematics than forward kinematics, especially for complex articulated figures with many joints and few end-effectors?
  6. What are the advantages of an animation system that incorporates dynamics (physics)? What are the challenges?
  7. Derive the equations for computing u and v for the Beier & Neeley morph with one line-pair.
