FK/IK Switching: Matching IK to FK

• Exploit the “translationâ€? abilities of constraints

• The easy part:

  • Each FK limb carries a copy of the control object
  • Copy has same pivot & local orientation as the original
  • Step by step IK > FK script:
    • Duplicate IK control (in same space as original)
    • Point & orient constrain duplicate to FK limb's copy
    • Copy duplicate's xform values over to original control
    • Delete duplicate

• Repeat for all IK controls (eg, world & body space)
