GLUPWLCURVE()							 GLUPWLCURVE()

NAME
       gluPwlCurve - describe a	piecewise linear NURBS trimming	curve

C SPECIFICATION
       void gluPwlCurve( GLUnurbs* nurb,
			 GLint count,
			 GLfloat* data,
			 GLint stride,
			 GLenum	type )

       delim $$

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-dimen-
       sional (u and v)	parameter space. If it is GLU_MAP1_TRIM_3, then	it de-
       scribes	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.
