Stereo rendering, 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 non-planar single-center projections, such as cylindrical and spherical projections in real-time, is still a challenge. This paper presents the results of adapting existing image-based and object-based approaches for generating interactive stereoscopic non-planar projections for polygonal scenes on consumer graphics hardware. 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 these both approaches with respect to selected criteria.
