Here is a demo with the help of David Johnson from Mind Opera using Dataton’s Watchout™ software with multiple SHOWWX projectors. Using up to 3 projectors, we were able to create a seamless projected image approximately 10 feet long by 3 feet tall. Real-time modifications include warping the video to remove key-stoning—the projectors were in a semi-circle, but the images are more or less straight.
We also took a standard lampshade and projected a seamless video using two projectors.
The scan lines seen in the video are artifacts from the video camera shutter not keeping up with each projector. They are not seen in person.
