Finger tips now also have a z value indicating the distance from the Kinect in mm. I've already got some ideas how to use this!
I've added three configuration "templates": default, fast and accurate. I'll tweak these settings, but for now I've just picked some values which I thought reasonable.
... and I've fixed a dispose problem that lead to performance issues in the sample app when the hand and finger detection button was clicked more than once.
Get the release here, the source code is here.
