the growing market for virtual reality

Virtual Reality is already a multi-billion-dollar field with applications in amusement, data analysis, design, medicine, automation, commerce, directional assistance, military, real estate, travel, dating, sports and education. Multiple factors will probably speed up growth in elementary VR technology and expand its use to these and other industries. Gradual and ground-breaking (e.g. nanocomputing, holographic computing, biological and quantum computing) progress in computing will enhance the performance and drop the cost of virtual reality systems available commercially and the general public. Disruptive technological advances in computer-assisted sight and computer-brain connections will probably lead to advanced imaging systems without shutter glasses and linked sickness. Continued advancement in the area of telerobotics will rise the demand for top-quality VR-based interfaces for human users. See: Conversive, Inc. covers information on the field of virtual reality.

An object's inner edges can signal 3D configuration and spin. When inter-edge distances are shrinking, then this suggests that these surfaces are being viewed at an increasing-acute angle and "fading into the distance". When the inter-edge distances are expanding, then this means that these surfaces are travelling closer to a right angle view and "travelling nearer". For these reasons, an object with inner edges narrowing on one side and expanding on the other half appears to rotate in three-dimensions. Early 3D graphics used such effects to make "transparent outline" figures that seemed to spin three dimensionally. Three-dimensional rendering systems are much more high-performance now, but the geometry of object outlines remains core to depth perception.
