Virtual model
Appearance

A Virtual Model, in the general sense, is a model of a physical object, be it a person, a room, a house, a city or a planet. This model is a digital description of the object (typically greatly simplified) that can be used in a computer simulation or Virtual Reality.
The most common examples of Virtual Models are those created in 3D for the purpose of visualisation. The field of architecture has greatly popularised the use of virtual models to animate fly-throughs of yet-to-be-built buildings.
The first known example of a virtual model is the Utah Teapot.
