NAME
	  glGetTexGendv, glGetTexGenfv,	glGetTexGeniv -	return texture
	  coordinate generation	parameters


     C SPECIFICATION
	  void glGetTexGendv( GLenum coord,
			      GLenum pname,
			      GLdouble *params )
	  void glGetTexGenfv( GLenum coord,
			      GLenum pname,
			      GLfloat *params )
	  void glGetTexGeniv( GLenum coord,
			      GLenum pname,
			      GLint *params )


     PARAMETERS
	  coord	  Specifies a texture coordinate.  Must	be GL_S, GL_T,
		  GL_R,	or GL_Q.

	  pname	  Specifies the	symbolic name of the value(s) to be
		  returned.  Must be either GL_TEXTURE_GEN_MODE	or the
		  name of one of the texture generation	plane
		  equations:  GL_OBJECT_PLANE or GL_EYE_PLANE.

	  params  Returns the requested	data.

     DESCRIPTION
	  glGetTexGen returns in params	selected parameters of a
	  texture coordinate generation	function that was specified
	  using	glTexGen.  coord names one of the (s, t, r, q) texture
	  coordinates, using the symbolic constant GL_S, GL_T, GL_R,
	  or GL_Q.

	  pname	specifies one of three symbolic	names:

	  GL_TEXTURE_GEN_MODE	      params returns the single-valued
				      texture generation function, a
				      symbolic constant. The initial
				      value is GL_EYE_LINEAR.

	  GL_OBJECT_PLANE	      params returns the four plane
				      equation coefficients that
				      specify object linear-coordinate
				      generation.  Integer values,
				      when requested, are mapped
				      directly from the	internal
				      floating-point representation.

	  GL_EYE_PLANE		      params returns the four plane
				      equation coefficients that
				      specify eye linear-coordinate
				      generation.  Integer values,
				      when requested, are mapped
				      directly from the	internal
				      floating-point representation.
				      The returned values are those
				      maintained in eye	coordinates.
				      They are not equal to the	values
				      specified	using glTexGen,	unless
				      the modelview matrix was
				      identity when glTexGen was
				      called.

     NOTES
	  If an	error is generated, no change is made to the contents
	  of params.

     ERRORS
	  GL_INVALID_ENUM is generated if coord	or pname is not	an
	  accepted value.

	  GL_INVALID_OPERATION is generated if glGetTexGen is executed
	  between the execution	of glBegin and the corresponding
	  execution of glEnd.
