NAME
       gluLoadSamplingMatrices - load NURBS sampling and culling matrices

C SPECIFICATION
       void gluLoadSamplingMatrices( GLUnurbs* nurb,
				     const GLfloat *model,
				     const GLfloat *perspective,
				     const GLint *view )

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

       model	    Specifies a modelview matrix (as from a glGetFloatv call).

       perspective  Specifies a	 projection  matrix  (as  from	a  glGetFloatv
		    call).

       view	    Specifies a viewport (as from a glGetIntegerv call).

DESCRIPTION
       gluLoadSamplingMatrices	uses model, perspective, and view to recompute
       the sampling and culling matrices stored in nurb.  The sampling	matrix
       determines  how	finely a NURBS curve or surface must be tessellated to
       satisfy	 the   sampling	   tolerance	(as    determined    by	   the
       GLU_SAMPLING_TOLERANCE property).  The culling matrix is used in decid‐
       ing if a NURBS curve or surface should be culled before rendering (when
       the GLU_CULLING property is turned on).

       gluLoadSamplingMatrices	is  necessary only if the GLU_AUTO_LOAD_MATRIX
       property is turned off (see gluNurbsProperty).  Although it can be con‐
       venient to leave the GLU_AUTO_LOAD_MATRIX property turned on, there can
       be a performance penalty for doing so.  (A round trip to the GL	server
       is  needed to fetch the current values of the modelview matrix, projec‐
       tion matrix, and viewport.)
