My graphics computing career began at NASA Ames Research
Center, where I wrote scientific visualization software. This software
enabled scientists to examine three dimensional models of aircraft on the
computer screen, along with information such as air pressure and
temperature distributions. This could be computer-generated simulation data, or
flight test data measured by sensors on the surface of an actual aircraft.
I also wrote software that added stereophonic audio to
visualization systems, by generating sound waves from fluctuations in the
pressure data. The scientist would wear headphones and interactively move
the listening location within the data region. The simulated sound waves
reached the ear nearest to the sound source first, to provide realistic
directional perception.
