void GLAPIENTRY gluEndSurface( GLUnurbs* nurb )

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

DESCRIPTION
       Use gluBeginSurface to mark the beginning of a NURBS surface definition.
       After calling gluBeginSurface, make one or more calls to gluNurbsSurface
       to  define the attributes of the surface.  Exactly one of these calls to
       gluNurbsSurface  must  have  a  surface  type  of  GL_MAP2_VERTEX_3   or
       GL_MAP2_VERTEX_4.  To mark the end of the NURBS surface definition, call
       gluEndSurface.

       Trimming of NURBS surfaces is supported with gluBeginTrim,  gluPwlCurve,
       gluNurbsCurve,  and  gluEndTrim. See the gluBeginTrim reference page for
       details.

       GL evaluators are used to render the NURBS surface as a set of polygons.
       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 surface with normals; the
       texture coordinates and normals are also described as NURBS surfaces:

       gluBeginSurface(nobj);
          gluNurbsSurface(nobj, ..., GL_MAP2_TEXTURE_COORD_2);
          gluNurbsSurface(nobj, ..., GL_MAP2_NORMAL);
          gluNurbsSurface(nobj, ..., GL_MAP2_VERTEX_4); gluEndSurface(nobj);
