virtual reality and product design

Virtual reality can also be a big help for design in the fields of engineering and manufacturing, building design and construction, biotechnology and nanopharmacology, chemistry and modeling at the molecular scale, medicine and bionics, the clothing industry, and the Arts. Three-dimensional artificially constructed molecules and biological structures may be fabricated and handled virtually. Electronics can be assembled and tested absent creation of a physical prototype. Virtual modeling clay can be shaped into various forms for either aesthetic or functional purposes. Link to SIGGRAPH provides further information about VR.

Besides its use in navigation of fighter planes and ships, virtual reality has several potential military uses including telerobotics for surveillance or (eventually) active battle in dangerous areas. VR-based simulations are also helpful for combat training and anti-terrorism scenarios. Link to Virtual Tours Vancouver, Washington provides more information.
