Download the IK Source Code
I have committed the Away3D version of the IK source code along with the dragon demo I blogged on earlier to the Away3D repository in the ‘IK’ branch. Feel free to check it out. Sorry it took so long but I have been very busy with paid work and my regular job lately.

This is my first commit and as such is very basic. Essentially, it’s just the math needed to solve the IK problem numerically without any sort of error checking or joint angle restrictions. If you decide to play with it you will need to do a lot of tweaking in order to get your application to work correctly but it still has a lot of potential. I will be doing one more demo (robotic arm) and then I will start adding ‘utility’ functions in order to make development of interactive IK applications easier and more robust.
Away3D Inverse Kinematics
Inverse Kinematics Superimposed on Key-framed Animation
I was inspired to create some basic inverse kinematics functionality for the Away3D open source library when I had read that they had added collada bones functionality to their project. My first demo of inverse kinematics with the Away3D version can be seen here. The dragon’s head, neck and tail can be controlled interactively with inverse kinematics but the flying animation is key-framed. The inverse kinematics code for the head, neck and tail simply overrides the key-framed animations.
I know a lot of you have been asking for the source to the robot arm demo that I did in PV3D but I would rather release the Away3D version because I’m going to continue to develop and debug it. I’ll see if I can provide the source to the dragon demo I did in Away soon.
New Site
I finally realized that I won’t ever have the time to finish my flash site so I thought I would just go ahead and create a simple Word Press blog. I’ll start posting my experiments and work as I have time.
