glLoadIdentityDeformationMapSGIX(3G)			      OpenGL Reference



NAME
     glLoadIdentityDeformationMapSGIX -	replace	current	deformations with the
     identity deformation


C SPECIFICATION
     void glLoadIdentityDeformationMapSGIX( GLbitfield mask )


PARAMETERS
     mask  Specifies the set of	deformations that are to be replaced with the
	   identity deformation.  Normally will	be the logical-OR of zero or
	   more	of the following bits (though other bits may also be included,
	   for upward compatibility):  GL_GEOMETRY_DEFORMATION_BIT_SGIX,
	   GL_TEXTURE_DEFORMATION_BIT_SGIX.

DESCRIPTION
     glLoadIdentityDeformationMapSGIX replaces the deformations	selected by
     mask with the identity deformation.  It is	significantly faster than
     specifying	a sequence of identity deformations with glDeformationMapSGIX.

     The identity deformation map is of	order 2	in each	of u, v, and w.	 Its
     pre-image is bounded by u1=v1=w1=0	and u2=v2=w2=1.	 The control points
     are (0,0,0),(0,0,1),(0,1,0),(0,1,1),(1,0,0),(1,0,1),(1,1,0), and (1,1,1).

     For a detailed description	of deformation maps, see glDeformationMapSGIX.

NOTES
     glLoadIdentityDeformationMapSGIX is part of the SGIX_polynomial_ffd
     extension,	not part of the	core GL	command	set.  If
     GL_SGIX_polynomial_ffd is included	in the string returned by glGetString
     when called with argument GL_EXTENSIONS, extension	SGIX_polynomial_ffd is
     supported by the connection.  See glIntro for more	information about
     using extensions.

ERRORS
     Note that it is not an error for mask to contain bits other than those
     listed above.

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

ASSOCIATED GETS
     glGetMap with arguments GL_GEOMETRY_DEFORMATION_SGIX and
     GL_TEXTURE_DEFORMATION_SGIX
