I suspected that. Unfortunately there isn't just one checkerboard, there are hundreds of versions, depending on which squares are visible, so that won't be so convenient. (FYI, we're recreating a perceptual stimulus for vision research - see

What I've done most recently is to do all the math by hand, finding the intersection of the line between the camera and each point in the checkerboard, and the plane onto which I want the points projected. This seems to "mostly work", aside from some small error that I haven't been able to track down. Gets a little messy since I'm dealing with head-tracking and a PowerWall.
