This approach to 3D projection could be the technology we have been waiting for. Multiple pico-projectors are used to create a seamless 3D experience. There are lots of approaches to creating 3D displays, but Spheree is a new approach to projecting a realistic model. It uses a spherical projection surface and an array of pico-projectors in place of one or two large high power projectors. The trick is all in the software - you might have guessed that - which automatically calibrates the projectors to produce an even display with no blind spots or other distortions. The whole assembly is light, low-power and doesn't need any special optics - the pico-projectors are unmodified.
