The Implementation of Virtual Reality

Steve Bryson is an employee of Computer Sciences Corporation working under contract for the Applied Research Office of the Numerical Aerodynamics Simulation Systems at NASA Ames Research Center.

This course provides an introduction to the issues encountered when implementing a virtual reality application. We will start with a description of display, interaction and computation concepts and hardware. Then the issues of performance and their implication will be examined. Finally, a systematic framework for the design of useful virtual environments will be presented. Avoiding pitfalls and finding effective compromises between conflicting requirements will be stressed.

Modern Optical Testing

James C. Wyant is a professor at the Optical Sciences Center at the University of Arizona and the president and founder of WYKO Corporation.

This course describes the basic interferometry techniques used in the evaluation of optical components and optical systems. It discusses interferogram interpretation, computer analysis, and phase-shifting interferometry, as well as various commonly used wavefront-measuring interferometers. The instructor describes specialized techniques such as testing windows and prisms in transmission, testing 90-degree prisms and corner cubes, measuring index inhomogeneity, measuring radius of curvature, testing cylindrical and aspheric surfaces, determining the absolute shape of flats and spheres, and the use of infrared interferometers for testing ground surfaces. The course also covers state-of-the-art direct phase measurement interferometers.
