Interactive Environments
There are several types of interactive environments. One is to re-create 3D space with visual representations of the museum by a 3D architectural metaphor, which provides a sense of place using various spatial references. They usually use 3D modelling, VRML (Virtual Reality Modelling Language) and now X3D(successor to VRML) for viewing. There have been introduced various kinds of imaging techniques for building virtual museums, such as infrared reflectography, X-Ray imaging, 3D laser scanning, IBMR (Image Based Rendering and Modeling) techniques. In the case of EU-funded projects, the ViHAP3D, a new virtual reality system for scanning museum artifacts, has been developed by EU researchers. Another interactive three dimensional spatial environment is QTVR. Being a pre-rendered, fixed environment it is more restricted in regards to moving freely around in 3D space but the image quality can be superior to that of real-time rendered environments. This was especially the case in the mid 1990s when computing power and online speeds were limited.

Famous quotes containing the word environments:
“Corporate America will likely be motivated to support child care when it can be shown to have positive effects on that which management is concerned about—recruitment, retention and productivity. Indeed, employers relate to child care as a way to provide growth fostering environments for young managers.”
—Dana E. Friedman (20th century)
