     t2d, t2f, t2i, t2s, t3d, t3f, t3i,	t3s, t4d, t4f, t4i, t4s	- specifies a
     texture coordinate	tuple

     void t4d(double vector[4])

PARAMETERS    [Toc]    [Back]

     vector   is a 2, 3, or 4 element array depending on whether you call the
	      t2, t3, or t4 version of the routine.  The elements of the array
	      are the s, t, r and q texture coordinates	in this	order.	The
	      default for r is 0.  The default for q is	1.

DESCRIPTION    [Toc]    [Back]

     t sets the	current	texture	coordinates, s,	t, r, and q.  The specified
     texture coordinates remain	valid until they are replaced.	All draw modes
     share the same texture coordinates.

     Using texgen it is	possible for one or both of the	texture	coordinates to
     be	replaced by a graphics system generated	value.	The coordinate or
     coordinates that are not being replaced continue to be specified by t.

     s,	t, r, and q are	transformed, prior to use, by the Texture matrix,
     which is modified while mmode is MTEXTURE.

     Texture coordinates are ignored while texture mapping is not enabled.

NOTES    [Toc]    [Back]

     IRIS-4D G,	GT, and	GTX models, and	the Personal Iris, do not support
     texture mapping.  t is ignored by these machines.	Iris Indigo supports
     texture mapping except for	lines and points.  Use getgdesc	to determine
     whether texture mapping is	supported.  t cannot be	used while mmode is
     MSINGLE.
