Attic Under Directional Lights

Tien-Tsin Wong, Chi-Wing Fu and Pheng-Ann Heng "Attic Under Directional Lights", 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 a directional light source. The three bottom images show three snapshots when the panorama is viewed perspectively. Some curved lines are straightened. All results are generated from images, not geometrical objects.

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