Abstract

Horizontal-parallax-only holographic stereograms of nearly SDTV resolution (336 pixels by 440 lines by 96 views) of textured and normal-mapped models (500 polygons) are rendered at interactive rates (10 frames/second) on a single dual-head commodity graphics processor for use on MIT's third-generation electro-holographic display. The holographic fringe pattern is computed by a diffraction specific holographic stereogram algorithm designed for efficient parallelized vector implementation using OpenGL and Cg vertex/fragment shaders. The algorithm concentrates on lightfield reconstruction by holographic fringes rather than the computation of the interferometric process of creating the holographic fringes.
