[comp.sys.sgi] polygon data to IGES format

adaptive@libra.cs.nps.navy.mil (zyda res acct) (10/27/90)

I am trying to convert image files consisting of polygonal
data into IGES format so that I can display the data using
AUTOCAD. I believe this requires converting the polygonal
data into parametric cubic splines and then storing the coefficients
of the parametric equations in IGES format. If anyone has had
experience with this conversion, I would appreciate a reply.

	thanks,
