  ray tracing
       
           A technique used in computer graphics to create
          realistic images by calculating the paths taken by rays of
          light entering the observer's eye at different angles.  The
          paths are traced backward from the viewpoint, through a point
          (a pixel) in the image plane until they hit some object in
          the scene or go off to infinity.  Objects are modelled as
          collections of abutting surfaces which may be rectangles,
          triangles, or more complicated shapes such as 3D splines.
          The optical properties of different surfaces (colour,
          reflectance, transmitance, refraction, texture) also affect
          how it will contribute to the colour and brightness of the
          ray.  The position, colour, and brightness of light sources,
          including ambient lighting, is also taken into account.
       
          Ray tracing is an ideal application for parallel processing
          since there are many pixels, each of whose values is
          independent and can thus be calculated in parallel.
