Common IK solvers for character rigs include FABRIK and CCD. CCD stands for which method?
ACellular Computational Dynamics
BConstant Connection Detector
CCyclic Coordinate Descent
DCumulative Curve Differential
Answer & Solution
Correct answer: C. Cyclic Coordinate Descent
CCD = Cyclic Coordinate Descent: iteratively rotates each joint to align the end-effector with the target. FABRIK = Forward And Backward Reaching IK.
