In this paper, we describe techniques for supporting a wide-field-of-view multiprojector curved screen display system. Our main contribution is in achieving automatic geometric calibration and efficient rendering for seamless displays, which is effective even in the presence of panoramic surround screens with the multiview calibration method without polygonal representation of the display surface. We show several prototype systems that use a stereo camera for capturing and a new rendering method for quadric curved screens. Previous approaches have required a calibration camera at the sweet spot. Due to parameterized representation, however, our unified calibration method is independent of the orientation and field of view of the calibration camera. This method can simplify the tedious and complicated installation process as well as the maintenance of large multiprojector displays in planetariums, virtual reality systems, and other visualization venues.
