The multi-projection display system “D-vision” has a hybrid curved screen for immersive virtual environments. The screen consists of differently shaped surface elements that are partial surfaces of such objects as planes, spheres, cylinders and tori. High-quality stereoscopic images are generated with 24 PCs and 24 projectors. Our rendering algorithm using image processing hardware and 3-D graphics hardware realizes a seamless and non-distorted projection on the hybrid screen. Distortion of the images observed by two or more users is also reduced by the characteristic seamless shape of the screen. In this paper, we give an overview of D-vision and the technologies used for the rendering and projection hardware. We also show the effectiveness of our system by comparing it with conventional immersive projection displays.
