Porting Trimming Curves

OpenGL trimming curves are very similar to IRIS GL trimming curves. The following table lists the IRIS GL functions for defining trimming curves and their equivalent OpenGL functions.

IRIS GL function	OpenGL function	Meaning
bgntrim	gluBeginTrim	Begins trimming-curve definition.
pwlcurve	gluPwlCurve	Defines a piecewise linear curve.
nurbscurve	gluNurbsCurve	Specifies trimming-curve attributes.
endtrim	gluEndTrim	Ends trimming-curve definition.
