virtual reality and texture mapping

"Texture mapping" is an effective means to create surfaces for three-dimensional virtual things by overlaying basically two-dimensional texture shadings on the exterior exteriors of objects. Depth perception of these surfaces can be then be refined through the application of shading and reflected light. "Ray tracing" takes light reflection to the next level by tracing individual beams of light as they reflect among things and eventually bounce from the exterior surfaces of objects to the viewer. Texture mapping, light shading, and ray tracing require considerable computing power, especially for complex computer moving worlds with travelling things. Conveniently with respect to computing economy, humans do not follow as much vision detail in moving things as in stationary things. Thus, computing effort in virtual reality can be conserved absent significant loss in perceptual realism by displaying the exteriors of moving things in less depth than the exteriors of stationery elements.

To qualify as being genuinely three-dimensional, the imaging component of a Virtual Reality (VR) system must create the sensation of depth and three-dimensionality. One way to make detail sensation is achieved using the shape of an object's edges. An object's outer edges form its outline. When an object's outline overlaps over that of another object, then it is seen as nearer than the second object. Similarly, if the outline is bigger compared to another object thought to be of similar magnitude, then it is seen as nearer than the other object. Lastly, when an object moves an extended distance in reaction to head movement than other things or the environmental background, then it is seen as nearer.
