Real engineering in a virtual world
VR technology can be thought of as the next point on a continuum that leads from 1-D data (such as the text and numbers on a finite element analysis printout), through 2-D drawings and 3-D solid models to 4-D digital prototypes that eventually will have texture and weight and can be held in one`s hand. If it lives up to its potential, VR could become just another tool--like 3-D CAD/CAM systems and FEA software--that can be used to pursue continuous improvements in design and manufacturing processes. For example VR could help manufacturers reduce the number of prototypes and engineering change orders (ECOs) generated during the product life cycle. Virtual reality could also be used to promote concurrent engineering. Because realistic virtual models are easier to interpret and interrogate than 2-D drawings or even 3-D solid models, they have the potential to simplify design reviews. They could also make it easier for non-engineers (such as salespeople and potential customers) to contribute to the design process. VR technology still has a way to go before it becomes a standard engineering tool, however. Peripheral devices are still being perfected, and engineers seem to agree that the jury`s still out on which peripherals are most appropriate for which applications. Further, advanced VR applications are largely confined to research and development departments of large corporations or to public and private research centers. Finally, potential users will have to wait a few years before desktop computers are powerful enough to run such applications--and inexpensive enough to survive a cost-benefit analysis.
