NAME
     glDeformSGIX - enable and/or disable deformations


C SPECIFICATION
     void glDeformSGIX(	GLbitfield mask	)


PARAMETERS
     mask  Specifies the logical-OR of zero or more of the following bits:
	   GL_GEOMETRY_DEFORMATION_BIT_SGIX, GL_TEXTURE_DEFORMATION_BIT_SGIX.
	   The deformations associated with the	bits that are nonzero in mask
	   are enabled;	the deformations associated with zero bits in mask are
	   disabled.

DESCRIPTION
     After the execution of glDeformSGIX, all the deformations whose bits are
     nonzero in	mask are enabled, and all the deformations whose bits are zero
     in	mask are disabled.

     For a detailed description	of deformations, see glDeformationMapSGIX.

NOTES
     glDeformSGIX is one of the	few GL commands	that may be executed between
     the execution of glBegin and the corresponding execution of glEnd.	 This
     allows deformations to be enabled and disabled for	subsets	of the
     vertices that make	up a strip or fan.

     glDeformSGIX 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
     GL_INVALID_VALUE is generated if mask contains nonzero bits other than
     those listed above.

ASSOCIATED GETS
     glGet with	argument GL_DEFORMATIONS_MASK_SGIX
