Virtual International Space Station by NASA Langley Research Center Spacecraft & Sensors Branch

Unrealty was something completely different. From late 1998 to late 2001, Unrealty used the most advanced "real-time" 3D technology available — video game technology — to allow you to explore a fully-realized, three-dimensional structure on your desktop PC, with no special hardware required. Unlike panoramic photographs or streaming video, you were able to walk anywhere and look at anything, from any angle, at any time.

Questions? Unrealty is no longer being licensed for any use at all, including casual downloading, and support is no longer available. Problems with newer video cards, operating systems or chipsets will not be addressed, and it is no longer possible to create your own content for the Unrealty software. Architectural firms, real estate developers, and educational or governmental organizations interested in real-time 3D models might consider contacting Daniel Patton or 3dx3. A next-generation Unrealty-style product may be found in the form of the UnrealEngine2 Runtime by Epic Games, developers of the 3D technology on which Unrealty was based. The original VSMM'99 paper on Unrealty is available here, and I can be contacted via unrealty underscore yourname at unrealty dot net, where "yourname" actually is your name, e.g. unrealty_quentinspammer.
