“Simplified� Reverse Foot

• Construction:

  • World space foot control object
    • pivot at ball of foot
  • Elevation proxy parented to foot control
    • Same pivot
    • Only 1 DOF – counter-rotates against elevation of foot control
  • Pivot proxies parented to elevation proxy
    • Elevation only
    • Elevation slaved to foot control via constraint or driver
    • Heel, ball, toe, ankle
  • Effector control parented to elevation proxy
    • Located at ankle
    • Point & orient constrained by all pivot proxies
    • Constraint weight handoff via expression

• Issues:

  • Eulerization
  • Foot control pivot issues
  • Ambiguities in position
