||Generating content for holographic three dimensional display systems is a
computationally heavy task. The problem differs from computer graphics
approaches used for two dimensional displays. This talk will discuss a
novel approach to Computer Generated Holography (CGH) from three
dimensional models. We will review the principle of a Spatial Light
Modulator based display, and discuss some existing rendering approaches.
The presented method is the first results of a recent analytic approach to
render wave fields and holographic interference patterns. We use mesh
based 3D models, and show how to compute the light distribution from each
triangle in the hologram plane.
This allow rendering of solid objects rather than point clouds, while
avoiding aliasing problems present in FFT-based approaches. The theory
behind the technique is presented together with some first results.
