Computer-Generated Holography
In the spring semester of 1999 at LSU, I taught an undergraduate "Computational Science" course for physics-majors whose focus was computer-generated holography (CGH). Midway through that semester, I posted the following paragraphs on the LSU Physics & Astronomy web server, accompanied by a Table of Contents that pointed to various class-note chapters.

Preface
The concept of computer-generated holography (CGH) has been of interest to me for a number of years because my astrophysics research group relies heavily upon animation sequences of complicated volume-rendered images to interpret the results of our large-scale fluid simulations and I am always looking for more effective ways to display/examine these complex three-dimensional structures. In the early 1990s I had the general impression that researchers knew quite well how to create holograms digitally from "virtual" computer-generated 3D surfaces but that it had not yet become practical to implement CGH techniques to make, for example, holographic movies because high-resolution digital images would require many many many (!) 2D FFTs. But it also seemed clear to me that with the advent of massively parallel computers (my group was effectively utilizing an 8K-node MasPar at the time), particularly ones that might utilize digital-signal-processing (DSP) hardware, the community might just be crossing a threshold that would make CGH techniques practical.
