Interactive stereo rendering for non-planar projections of 3d virtual environments

as an additional visual cue for humans, is an important method to increase the immersion into 3D virtual environments. Stereo pairs synthesized for the left and right eye are displayed in a way that the human visual system interprets as 3D perception. Stereoscopy is an emerging field in cinematography and gaming. While generating stereo images is well known for standard projections, the implementation of stereoscopic viewing for interactive non-planar single-center projections, such as cylindrical and spherical pro-jections, is still a challenge. This paper presents the results of adapting an existing image-based approach for generating interactive stereoscopic non-planar projections for polygonal scenes on consumer graphics hard-ware. In particular, it introduces a rendering technique for generating image-based, non-planar stereo pairs within a single rendering pass. Further, this paper presents a comparison between the image-based and a geometry-based approach with respect to selected criteria.
