Nowadays, with films like Avatar grossing more than the GNP of many small nations, it’s not surprising that many are taking a renewed interest in 3D technology. Just last spring, vision scientists and filmmakers at York University founded 3D Flic, a stereoscopic film research initiative destined to stake out Toronto’s own slice of the increasingly well-rendered 3D pie.
