Virtual Reality Modeling Language
VRML stands for Virtual Reality Modeling Language. Technically, VRML is neither virtual reality nor a modeling language. Virtual reality generally implies an immersive 3D experience, which typically requires a head mounted display (HMD) and 3D input devices, such as digital gloves. VRML neither requires nor imposes immersion. VRML provides a bare minimum of geometric modeling features but contains numerous features unavailable in a modeling language.
The Web3D Consortium has been formed to further the collective development of the format.
VRML has never seen much serious widespread use. One reason for this may have been the lack of available bandwidth.
