Computer Animation

FK & IK

Character-animation studies spanning forward kinematics, inverse kinematics and grounded foot placement.

PUBLISHED
FK & IK

In this project, I implemented some basic functions with Forward Kinematics & Inverse Kinematics.

Foward Kinematics

Implemented basic FK logic:



Inverse Kinematics

Implemented Inverse Kinematics with serveral methods:

  • Limb-based
  • CCD (Cyclic Coordinate Descent)
  • Pseudo-Inverse


Foot IK

Implemented the guide point logic in Unity with Foot IK to make character keep walking smoothly to the target point with foot standing on ground correctly.
