gluPwlCurve()
NAME
  gluPwlCurve - describe a piecewise linear NURBS trimming curve

SYNOPSIS
  void gluPwlCurve(
	  GLUnurbs* nurb,
	  GLint count,
	  GLfloat* data,
	  GLint stride,
	  GLenum type );

PARAMETERS
  nurb
      Specifies the NURBS object (created with gluNewNurbsRenderer()).

  count
      Specifies the number of points on the curve.

  data
      Specifies an array containing the curve points.

  stride
      Specifies the offset (a number of single-precision floating-point
      values) between points on the curve.

  type
      Specifies the type of curve. Must be either GLU_MAP1_TRIM_2 or
      GLU_MAP1_TRIM_3.

DESCRIPTION
  gluPwlCurve() 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.

NOTES
  To describe a trim curve that closely follows the contours of a NURBS
  surface, call gluNurbsCurve().
