> One approach would be to use SurfaceMapper – and possibly try using the SurfaceMapperGUI (may need to be updated). The problem with an algorithmic solution in this case is that very tiny variations in your cylinder surface or in the angle of your projection mounts will cause a pure geometric approach to create distortion. An alternative is to create a segmented, bezier-curve controlled surface that you can tweak at installation time and save the settings, like this: The GUI might ne…
