The Stereo end-Viewer is the critical part for success, in my opinion. Maybe slightly more tricky to control is inter-ocular 3D scene view convergence in a camera-phone. Digital cameras are tending toward "pinhole" cameras with "infinite" focus-depth and hence no focus-plane. 3D geometry from-Stereo is yet a bit less robust. Google "Street-View" is what we used to call QuickTime-VR and has been used as a basis for the design of some computer games ("Zork-II: Nemesis" -- I worked on it.) It requires a motorized camera tripod rotator head synchronized over an interface to the camera frame control. How far are we from LIDAR in a camera-phone? Is a DVD-RW laser big enough for LIDAR? Honestly, retail companies like Looxis will build glass blocks from 3D data files you supply. Why not set up a custom portrait-sculpture franchise in tandem with a company like Looxis? Minolta makes 3D scanners. They only need to evolve to the Digital-SLR camera scale before you have a lot of consumer-created 3D input content looking for the output medium. --Stewart Dickson (c) 2010 (Some rights reserved) G.
