GLUDELETENURBSRENDERER(3G)												GLUDELETENURBSRENDERER(3G)

NAME

       gluDeleteNurbsRenderer - destroy a NURBS object

C SPECIFICATION

       void gluDeleteNurbsRenderer( GLUnurbs* nurb )

PARAMETERS

       nurb  Specifies the NURBS object to be destroyed.

DESCRIPTION

       gluDeleteNurbsRenderer  destroys  the  NURBS  object  (which  was  created  with  gluNewNurbsRenderer)  and frees any memory it uses.  Once
       gluDeleteNurbsRenderer has been called, nurb cannot be used again.

NAME

       gluBeginCurve, gluEndCurve - delimit a NURBS curve definition

C SPECIFICATION

       void gluBeginCurve( GLUnurbs* nurb )

       void gluEndCurve( GLUnurbs* nurb )

PARAMETERS

       nurb  Specifies the NURBS object (created with gluNewNurbsRenderer).

DESCRIPTION

       Use  gluBeginCurve to mark the beginning of a NURBS curve definition.  After calling gluBeginCurve, make one or more calls to gluNurbsCurve
       to define the attributes of the curve.  Exactly one of  the  calls  to  gluNurbsCurve  must  have  a  curve  type  of  GL_MAP1_VERTEX_3	or
       GL_MAP1_VERTEX_4.  To mark the end of the NURBS curve definition, call gluEndCurve.

       GL  evaluators  are  used  to  render  the  NURBS  curve  as a series of line segments.	Evaluator state is preserved during rendering with
       glPushAttrib(GL_EVAL_BIT) and glPopAttrib().  See the glPushAttrib reference page for details on exactly what state these calls preserve.

EXAMPLE

       The following commands render a textured NURBS curve with normals; texture coordinates and normals are also specified as NURBS curves:

       gluBeginCurve(nobj);
	  gluNurbsCurve(nobj, ..., GL_MAP1_TEXTURE_COORD_2);
	  gluNurbsCurve(nobj, ..., GL_MAP1_NORMAL);
	  gluNurbsCurve(nobj, ..., GL_MAP1_VERTEX_4); gluEndCurve(nobj);
