DESCRIPTIONgluPwlCurve 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. If type is GLU_MAP1_TRIM_2, then it describes a curve in two-dimensional (u and v) parameter space. If it is GLU_MAP1_TRIM_3, then it describes a curve in two-dimensional homogeneous (u, v, and w) parameter space. See the gluBeginTrim reference page for more information about trimming curves.NOTESTo describe a trim curve that closely follows the contours of a NURBS surface, call gluNurbsCurve.SEE ALSOgluBeginCurve, gluBeginTrim, gluNewNurbsRenderer, gluNurbsCurve
