Chapter 6: Review

• Arm rigs strongly determined by kinematics

• They're variable, so they usually need switching

• For locomotion animations:

  • FK or body space IK; Torso or body space pole vectors

• For performance animations:

  • FK or world space IK; Body space pole vectors

• For crawling:

  • PV-centric IK or world space PV's

• For aiming

  • “Pseudo-FKâ€? rotate control at shoulder

• Key Concepts:

  • FK-IK switching
  • Pole Vectors
  • Kinematics
  • Spaces
