Does anyone have any experience drawing smooth curves on an IRIS using a package called NURBS? If so, please tell me where I can get it and what you think of it. I am looking for a better way of drawing curves than is available in the graphics library at present. Thanks Much!

NURBS is not a package (well maybe it is but I've never heard of it) but stands for: Non-Uniform Rational B-Splines. These are now available from the graphics library. Here are the available on-line man pages: bgnsurface, endsurface (3G) - delimit a NURBS surface definition bgntrim, endtrim (3G) - delimit a NURBS surface trimming loop getnur (3G) - returns the current value of a trimmed NURBS surfaces display property getnurbsproperty (3G) - returns the current value of a trimmed NURBS surfaces display property nurbscurve (3G) - controls the shape of a NURBS trimming curve nurbssurface (3G) - controls the shape of a NURBS surface pwlcurve (3G) - describes a piecewise linear trimming curve for NURBS surfaces setnur (3G) - sets a property for the display of trimmed NURBS surfa ces setnurbsproperty (3G) - sets a property for the display of trimmed NURBS surfa ces trimnurbs (1) - create, display and edit trimmed, non-uniform, rationa l B- Spline surfaces (NURBS) -- "Mister!
