Reverse projectScreenPointToPlane linear algebra

By nickoneill on Sat, 09/29/2012 - 03:07

I'm looking to do something that's the reverse of what projectScreenPointToPlane does in the dominoes sample and I'm having trouble reversing the linear algebra in that function. I'd like to get the x,y position on the screen where the center of the current tracking image is located. Has anyone done anything similar?
