OK, thanks for the explanation. How can this be used for distortion-correct projection for curved screens? > Martin - I didn't understand what switching VR/2D projection does in > your case, does it switch on/off distortion correction? In '2D projection' mode, we pretend the cylinder is planar, and can then use a 2D rectangular region on this plane as our viewport. The calibration still has to make sure that a rendered rectangle is still rectangular on the plane (because it is not really a plane).
