A simple example of IK is the human arm: While we intuitively know the target position of an object we want to reach for, our brains need to figure out how much to move each joint in our arm to get to that target. It starts from the initial pendulum model with constrained end point (zero DOF). Positions and velocities of links are defined by the values and speeds of the scalar joint parameters (angles, distances). Instead of posing each bone in a chain from the base to the tip, IK solves the rotations of preceding bone(s) in the chain automatically based on the position of the IK-constrained bone. following the approach of inverse kinematics. image for clarification. Not only to bring a robot arm, point A to Point B there are a lot of usage of inverse kinematics in every. Drawing an analogy to the traditional use of skeleton-based inverse kinematics for posing skeletons, we define mesh-based inverse kinematics as the problem of finding meaningful mesh deformations that meet specified vertex constraints.
