Inverse Kinematics in Flash
Posted on July 19, 2006
Just launched a project for simyo that uses three inverse kinematic figures (if you don't speak German, just click two large orange buttons).
Inverse kinematics is the process of determining the parameters of a jointed flexible object in order to achieve a desired pose
The ik chain is uni-directional, which means you can only grab one end point of the chain (the left foot) to shake / throw them around. This has the added benefit of making the maths for restricting angles a lot simpler (although it still took two days to get the trigonometry right). This page was useful for the basic trig, but I ended up rewriting the constriction functions entirely. Here's a demo where you can play with the underlying skeleton and see the constraining angles.

Hi NoName,
the .fla is a bit messy, I'm embarrased to say. I was thinking of writing a tutorial when I find the time... Just another one of those projects.

Hi, i am very interested in your Work.
I am a flash animator a i wish to find one day an easy system that allow people like me to build animatable character with IK in Flash. If ever you need a test person for your tools, i am your man.
