perception of distance in virtual reality environments

In order to be genuinely immersive, the camera component of a virtual reality system must create the sensation of detail and three-dimensionality. One way to make depth sensation is achieved using the geometry of an object's edges. An object's outer edges create its outline. When an object's outline covers another object, then it is perceived as nearer than the second object. Also, if the outline is bigger than that of another object believed to be of similar actual size, then it is seen as closer than the second object. Finally, when an object moves a greater distance in reaction to motion of one's head than other components or the background setting, then it is seen as closer. Also, AtmoWire includes coverage of VR related technologies.

Three-dimensional imaging of elements can be achieved through the representation of their surfaces. Surface texture, shading, and reflected lighting provide important cues for three-dimensional sensation. Two-dimensional texture shadings are used for surfaces in a process called "texture mapping." These surfaces can then be shaded and enhanced with reflected light to improve detail perception. We all are accustomed to things illuminated by one light source above, so shading and light reflection based on an overhead light source gives strong cues for detail sensation. One of the more challenging methods of lighting virtual elements ofvolves tracing the rays of individual light rays as they are reflected and refracted from the elements. This is known as "ray tracing." Also, Virtual Tours Port Jervis, New York provides information on this topic.
