IGL

from The Free On-line Dictionary of Computing (8 July 2008)
IGL

   Interactive Graphic Language.  Used primarily by Physics Dept
   at Brooklyn Poly, uses numerical methods on vectors to
   approximate continuous function problems that don't have
   closed form solutions.

   [Is this being confused with Tektronix's graphics library by
   the same name?]
