Getting started with Inverse Kinematics in U3D

Inverse kinematics (IK) is a technique used in game engines and animation software to control the movement of a character’s joints in a more realistic way. It allows the game developer to specify the desired end position for a character’s limb, and then calculates the rotations of the individual joints that are required to reach that position. This is the opposite of forward kinematics, where the position of a limb is determined by the rotations of its joints.

IK is particularly useful
