Experimenting with a new balance/control algorithm based on the COM momentum. First result on a simple rig.
Some improvement. He doesn't wipe out on a 20 degree downhill slope. Although the transition to flat ground at the bottom is too much.
I put my Stable Proportional Derivative controller (PD substitute) up on github github.com/Phong13/UsefulUti…

Testing the physically simulated walking system with a much larger heavier powered ragdoll. #gamedev
Rewrote the IK functions so they generate angular velocity for each limb as well as rotation. This angular velocity makes the Inverse Dynamics a lot more accurate. Still not perfect but the gait is faster and more natural.

Just updated the "SamCon" code repo that was open-sourced last year. Now, it supports multiprocess parallel, a new humanoid similar to SMPL that means we can use large-scale dataset like AMASS to generate reference motion. What's important is code has become cleaner😅

this is really satisfying if you land it, using the banking to jump over the inside barrier, you can see the front right wheel glance off the barrier at the end
The dino rig is walking a little better now. The biggest change was shrinking the foot colliders. #gamedev
