When you tried the approaches for the elbows, did you still use IK solvers and did you use the Vive Trackers on your elbows? Because it sounds to me like you were only tinkering with the elbows rotations so that it can benefit the IK solver, correct me if I’m wrong. IK solvers aren’t beneficial if we use Vive Trackers on our elbows, there’s definitely a better solution because it’s enough tracking points to drive each joint independently on the arms besides the clavicles. And tracking each joint is obviously more accurate than IK
I’m not interested in overriding the elbows calculation if that means keeping the IK solvers, because I want to completely discard the arm’s IK solvers and replace them with an FK-like solution. Is that possible? You still haven’t answered my question.
Also, no offense, but I just can’t see CCDIK being any different when we bring our arms down. I’ll eat my words if it does work but every IK solver is bound to have the same “non stretch arm” problem because the wands gradually closes in towards the shoulders once we bring arms down (from a T-pose to an A-pose). And no IK solver in the world (besides Ikinema’s) can accurately solve that “non stretch arm” problem.
I’m not looking forward to this CCDIK feature, I am however excited for the clavicle and spine feature. I’ll eat my words if you managed to figure out the “non stretch arm” with the CCD IK solution but I personally believe that the safest way to track the arms is to track the shoulder and elbow joints independently WITHOUT an IK solver. Can’t beat an FK-like solution
