Sorry, Richard, but I forgot to point out that you must be at Release 3.0,
which is standard on the IRIS 4D/GT.  If you are still at Release 2.0 on
the IRIS 4D, this code can be converted:

	change references from lsetdepth to setdepth
	change czclear to RGBcolor(), clear(), and zclear()
	change bgnpolygon(), n3f(), v3f(), endpolygon() to
		normal(), pmv(), normal(), pdr(), normal(), ..., pclos()

See the Graphics Library Guide for the precise syntax of these subroutines.

Thanks, again.
