In the case of Renault and other OEMs, visualization does not try to eliminate all prototypes or all design models. Just the non-starters. So are its Tier 1 suppliers. He's referring to the redundancies of drawing a part in Catia, milling a model, verifying it, then having everybody scrutinize the model. Now, with all of the verification and analysis tools in the workstation, a physical model is not needed until late in the design development process.
Light reflections can show surface imperfections.
You don't want to see any bumps. Using real-time analysis, Bradley can manipulate that surface to evaluate how the light reflections will change. Once Bradley is done with the design on the computer, then it's sent to conference rooms set up with Catia and big screens for people to sit and critique the designs. An infrared signal triggers the liquid crystal shutters in stereosscopic shutter glasses, such as these CrystalEyes from StereoGraphics. The shutters' opening and closing is synchronized with the right and left perspectives that are alternately displayed on the monitor.
