Abstract or Summary
  • Phase-space trajectories are often used to describe a system's stability or response characteristics. It is desirable to observe such a phase-space trajectory directly from an analog simulation of a system, but a conventional oscilloscope display does not provide an axis for the third variable, A third axis could be provided by simulating visual parallax in two planar displays and viewing them stereoscopically. The third axis is then provided by depth perception associated with binocular vision. The method of producing visual parallax developed in this thesis involves generating a diode equation approximation of the differential parallax equation from optical theory. Once the differential parallax is generated, it is used to modify a planar display so three dimensional vision is simulated with the aid of a stereoscopic viewer. Photographs of laboratory results are provided as evidence of the success of this approach to the display of phase-space trajectories.
