Creating 3D environments without polygons!

Igor Hardy writes: "I've conducted a very interesting interview concerning a new episodic indie adventure game series called Casebook. What's quite uncommon, especially for these kind of independently developed and published productions, they include professionally created FMV — the entire footage filmed in real locations. Yet what is even more interesting, the games use an innovative photographic technology that recreates a fully, explorable, 3D environment through the use of millions of photos instead of building from polygons. How it works exactly is explained by Sam Clarkson the creative director of the series."
