Design
We're going to make a 3D scanner using "structured light".  The components include:
   * A turntable, on which to place the object, which has a sensor for angular position.
   * Two cameras (web cams) for taking pictures of different sides of the object.
   * A light source, which can be nothing more complicated than a
     vertical slice of light (think a flaslight with a mask), but
     could be as complicated as a laser or a projector. We'll 
     shoot for simple.  Kyunghee will get a few sources.

   Data format:
      Two data structures.  First, a vector of angles (T):
          [T1, T2, T3, T4 ... TN]
      Second, a 2D array in which the rows index the angles
      in the vector (n), and columns are the distance for all Z slices.
         [[d00, d01, d02, d03 ... d0z],
          [d10, d11, d12, d13 ... d1z],
          ...
          [dn0, dn1, dn2, dn3 ... dnz]]

Parts to get
   * 2) Webcams that can ideally interface with windows/linux/os x,
     and function with python webcam libraries.  High resolution is 
     important, speed/framerate/etc. is not.  It is important that the 
     cameras be controllable from software.  Minimum 1.3 megapixel.

   * Light sources.  thin lines; masks and flashlights, etc.
