-.SH DESCRIPTION
-\%\f3gluPwlCurve\fP describes a piecewise linear trimming curve for a NURBS surface.
-A piecewise linear curve consists of a list of 
-coordinates of points in the parameter space for the
-NURBS surface to be trimmed. These points are connected
-with line segments to form a curve. If the curve is
-an approximation to a curve that is not piecewise linear, 
-the points should be close enough in parameter space that the 
-resulting path appears curved at the resolution used in the application.
-.P
-If \f2type\fP is
-\%\f3GLU_MAP1_TRIM_2\fP, then it describes a curve in two-dimensional (\f2u\fP 
-and \f2v\fP) parameter space. If it is \%\f3GLU_MAP1_TRIM_3\fP, then it
-describes a curve in two-dimensional homogeneous (\f2u\fP, \f2v\fP,
-and \f2w\fP) parameter space. 
-See the \%\f3gluBeginTrim\fP reference page for more information 
-about trimming curves. 
-.SH NOTES
-To describe a trim curve that closely follows the contours of a NURBS 
-surface, call \%\f3gluNurbsCurve\fP.
