Multiple View Generation for Auto-stereoscopic Displays

This paper presents several approaches for accelerating the view generation for auto-stereoscopic displays by exploiting the capabilities of current graphics cards. Besides rendering the scene multiple times, we also investigate 3D image warping for generating intermediate views from a number of reference images. While this approach may introduce artifacts, the particular view arrangement of a multi-view auto-stereoscopic display allows us to directly detect and fill holes during warping at a small additional cost. We show that multi-pass rendering and 3D image warping benefit from the utilization of the geometry shader and perform up to 40 percent faster compared to a multi-pass approach without geometry shader.
