Another example of "real 3D space" attached - created by an app called Canoma (really old link - but still descriptive) that came out in 1999 and used photogrammetry to create photorealistic 3D environments. It was way ahead of its time - and such a delight to use (like Hype). Bought from its original owners (MetaCreations) & buried by Adobe ("Atmospheres").
What is interesting about this demo is it used one of Vermeer's paintings (called "the Music Lesson") as its basis. Vermeer is believed to have used a camera obscura to set the geometry of his works which makes it a viable image to create a 3D fly around - into a room that existed over 350 years ago.
Perhaps version 5 of Hype might offer a similar ability to create graphic "immersive" environments?
