The Virtual Reality Laboratory at the University of Iowa has developed novel technologies for visualization of physics-based simulation using realistic (indeed photorealistic) graphics that is based on PC workstations.

Large screen and multi-wall systems:  The VR Lab's methodologies for large screen rear or front projection has enabled us to simulate one-to-one scale vehicles, humans, weapons, and systems. 

LCD, CRT, and DLP projectors are used in our research. Our lab is equipped with state-of-the-art display technologies, unmatched anywhere else in the world.  Indeed, we are in the process of building the world's first 6-walled CUBE system that is PC based.

• Research Issues:
  - High quality quadbuffer stereoscopic visualization
  - High frame rates
  - High level of photorealism
  - High number of polygons per second
  - High number of polygons per channel
  - Dynamic levels of fidelity
  - Visualization of complex data
  -  Visualization of fluid flow, large dams, and complex topology
  - Visualization of biological data
  - Visualization of medical imaging data

a. The world's first 6-wall PC-based VR CUBE (under construction)
b. A 3-walled PC-based VR systems
c. A one walled large active viz system
d. A 3-walled large active system
e. A portable passive visualization system

Our facilities continue to grow, and we continue to add new technologies in terms of sensory interaction, presence, and perception.  We are particularly interested in human-computer interaction because of our close association with the Virtual Soldier Research program.
