Attic Under Spotlights

Tien-Tsin Wong, Chi-Wing Fu and Pheng-Ann Heng "Attic Under Spotlights", Technical Slide, SIGGRAPH'98.



Traditional panorama is an image with fixed illumination. The images shown in this slide demonstrate a new image-based rendering technique. It allows not just navigating the panorama, but also changing the lighting setup of the scene shown in the panoramic image. The top image shows an attic environment illuminated by several spotlights, each with different intensity. The three bottom images show three snapshots when the panorama is viewed perspectively. Note how the blue and white spotlights correctly illuminate the scene. All results are generated from images, not geometrical objects.

Hardware: SGI Octane.
Software: Proprietary illumination-controllable panorama renderer
