Abstract
Images for non-planar display systems are generated using polygon definitions that are pre-distorted using panel shear transforms. Initially, panel shear transforms are generated based on the configuration and orientation of a screen, a projector and a viewer. Polygons defined in model space are mapped to a two-dimensional space and then transformed to a panel space using the panel shear transforms. This transformation technique enables the use of standard two-dimensional rendering processes to scan-convert the polygons.
