real world behavior for virtual objects

In order to be categorized as Virtual Reality (VR), objects within the computer-created place should also allign with reasonable accuracy to the physical and biological laws relevant to their real counterparts. This is needed for the artificially-VR objects to appear real to the higher-order systems in the human brain, not merely lower-level perception. It is not enough for a cube to just appear like a cube, it should also behave like a cube concerning the quantity of matter, gravity, momentum, and other laws that direct the real world. This is more challenging with more challenging tangible or even biological components inside an artificially-generated setting. Imitating an organism is harder than artificially creating a geometric object. The page on Virtual People in a Computer World discusses similar topics.

To get intelligent animation of components in the setting, computer-artificially constructed elements should act in enough harmony with the tangible, living, or other rules to which their actual counterparts match so that the artificially-artificially constructed components seem realistic to higher-order processing by one's brain in addition to basic-level sensation. It is not requisite for Virtual Reality (VR) to have a geometric object appear like a cube; it should also behave reasonably like a cube when a human interacts with it. This standard becomes more difficult as the tangible and living complexity of the computer generated environment grows. To be specific, simulating a biological organism is harder than simulating a room of simple cubes, spheres, and other shapes. You may also see Virtual Tours Plano, Texas for more about VR.
