from what i remember of an old version of that program, you can change the positions it expects to find the dots in 3d as long as you follow a simple rule (like for 4 dots they can't be coplanar, I'm not sure about the requirements for 3 dots), so a generic pattern for the position of things in the face should work with minimum calibration
