Building Virtual Environments that are Reconfigurable, Scalable, Extensible with DIVERSE

The DIVERSE Course,
August 8, 2001

             

Abstract

This class will teach you how to construct Device Independent Virtual Environments- Reconfigurable, Scalable, Extensible (DIVERSE) applications. DIVERSE is comprised of two C++ application progamming interfaces that provide tools to write Performer based applications which can be run on a CAVETM, ImmersaDeskTM, HMD (head mounted displays), desktop and laptop without modification of the applications code.
