Report Success in Watchout 3D on Complex Multi Projector Curves in WATCHOUT FORUM Posted March 30, 2018 The calibration of things. Even when using known locations, carefully entered based on measurements and extensive drafting image was always off. And calibration using points, even when measured out and gridded, were horrible failures resulting in projectors being flung to locations in space that would have been hundreds of meters outside the venue. Including with projectors on their sides, and projectors in normal orientation. Honestly the only success i've had where 3D has worked as it should, was on a simple L-shaped wall the projector was hitting at a simple 45 degree angle with a 1.0 lens in landscape.
