ARCGraph -> Tek 4693D

[Brent L. Bates AAD/TAB MS361 x42854]

    ARCGraph is a metafile format designed at Ames Research Center
and is used and produced by the Ames software: PLOT3D, GAS, SURF,
FAST, and others.  ARCGraph has options for pixels, voxels, 2D & 3D lines,
polygons with all sorts of shading, vectors, almost any kind of graphical
entity presently being used.  Since the SGI imagelib is not documented,
I have documentation for ARCGraph, and most of the software I use
produces & use's it, I decided to use it as my standard metafile reference.
I don't use SGI imagelib at all so I don't have anything that works with
it.  If SGI ever decides to support and document it I may change,
but not until then.
    If you want to try to modify my software to read SGI imagelib files,
try looking at the source files in 4Dgifts/iristools.  The source files
are the only "documentation" available for the imagelib.
    Sorry I can't be of any more help.

 getting use unknown)
