Seamless Multi-Projector Display on Curved Screens

We describe a new technique to display seamless images using overlapping projectors on curved surfaces. Our method addresses issues such as automatic registration, smooth intensity blending and efficient render-ing. Previous techniques for automatically registered seamless displays have focused mainly on planar dis-plays. Techniques for curved screens currently involve cumbersome manual alignment to make the installation conform to the intended design.
