use of wire figures for three-dimensional graphics

First generation 3D graphics used the basic geometry of object edges, generally groups of straight lines, to create moving three-dimensional, invisible "transparent outline" figures. While volumetric graphics have become significantly more advanced, the foundational geometry of object outlines remains central to 3D rendering. User Interface Designs discusses some of these issues as well.

In order to successfully achieve complete engagement of a person inside a Virtual Reality (VR) setting, the Virtual Reality (VR) system should involve vital sensory pathways in a believable manner. The most vital senses by which people learn about their surroundings are sight, hearing, and touch. Thus, these are the basic elements of today's VR systems. If sensory input from these things is not coordinated, then immersion will not be achieved. For instance, latency between location determination by the inner ear and location determination by vision will detract from the feeling of immersion in a realistic world. Similarly, delays or gaps between hearing and touch or between hearing and vision also create difficulties. Such lags cause sickness. Similar topics at Virtual Tours Arlington, Texas .
