This	  position, called the raster position,	is used	to position	  pixel	and bitmap write operations. It	is maintained with	  subpixel accuracy.  See <STRONG>glBitmap</STRONG>, <STRONG>glDrawPixels</STRONG>, and	  <STRONG>glCopyPixels</STRONG>.	  The current raster position consists of three	window	  coordinates (x, y, z), a clip	coordinate value (w), an eye	  coordinate distance, a valid bit, and	associated color data	  and texture coordinates.  The	w coordinate is	a clip	  coordinate, because w	is not projected to window	  coordinates.	<STRONG>glRasterPos4</STRONG> specifies object coordinates x,	  y, z,	and w explicitly.  <STRONG>glRasterPos3</STRONG>	specifies object	  coordinate x,	y, and z explicitly, while w is	implicitly set	  to 1.	 <STRONG>glRasterPos2</STRONG> uses the argument	values for x and y	  while	implicitly setting z and w to 0	and 1.	  The object coordinates presented by <STRONG>glRasterPos</STRONG> are treated	  just like those of a <STRONG>glVertex</STRONG>	command:  They are transformed	  by the current modelview and projection matrices and passed	  to the clipping stage.  If the vertex	is not culled, then it	  is projected and scaled to window coordinates, which become	  the new current raster position, and the	  <STRONG>GL_CURRENT_RASTER_POSITION_VALID</STRONG> flag	is set.	 If the	vertex	  <EM>is</EM> culled, then the valid bit	is cleared and the current	  raster position and associated color and texture coordinates	  are undefined.	  The current raster position also includes some associated	  color	data and texture coordinates.  If lighting is enabled,	  then <STRONG>GL_CURRENT_RASTER_COLOR</STRONG> (in RGBA	mode) or	  <STRONG>GL_CURRENT_RASTER_INDEX</STRONG> (in color index mode)	is set to the	  color	produced by the	lighting calculation (see <STRONG>glLight</STRONG>,	  <STRONG>glLightModel</STRONG>,	and	  <STRONG>glShadeModel</STRONG>).  If lighting is disabled, current color (in	  RGBA mode, state variable <STRONG>GL_CURRENT_COLOR</STRONG>) or color index	  (in color index mode,	state variable <STRONG>GL_CURRENT_INDEX</STRONG>) is	  used to update the current raster color.	  Likewise, <STRONG>GL_CURRENT_RASTER_TEXTURE_COORDS</STRONG> is	updated	as a	  function of <STRONG>GL_CURRENT_TEXTURE_COORDS</STRONG>, based on the texture	  matrix and the texture generation functions (see <STRONG>glTexGen</STRONG>).	  Finally, the distance	from the origin	of the eye coordinate	  system to the	vertex as transformed by only the modelview	  matrix replaces <STRONG>GL_CURRENT_RASTER_DISTANCE</STRONG>.	  Initially, the current raster	position is (0,	0, 0, 1), the	  current raster distance is 0,	the valid bit is set, the	  associated RGBA color	is (1, 1, 1, 1), the associated	color	  index	is 1, and the associated texture coordinates are (0,	  0, 0,	1).  In	RGBA mode, <STRONG>GL_CURRENT_RASTER_INDEX</STRONG> is always	  1; in	color index mode, the current raster RGBA color	always	  maintains its	initial	value.     <STRONG>NOTES</STRONG>	  The raster position is modified both by <STRONG>glRasterPos</STRONG> and by	  <STRONG>glBitmap</STRONG>.	  When the raster position coordinates are invalid, drawing	  commands that	are based on the raster	position are ignored	  (that	is, they do not	result in changes to GL	state).	  Calling <STRONG>glDrawElements</STRONG> may leave the current color or	index	  indeterminate.  If <STRONG>glRasterPos</STRONG> is executed while the current	  color	or index is indeterminate, the current raster color or	  current raster index remains indeterminate.	  To set a valid raster	position outside the viewport, first	  set a	valid raster position, then call <STRONG>glBitmap</STRONG> with NULL as	  the <EM>bitmap</EM> parameter.     <STRONG>ERRORS</STRONG>	  <STRONG>GL_INVALID_OPERATION</STRONG> is generated if <STRONG>glRasterPos</STRONG> is executed	  between the execution	of <STRONG>glBegin</STRONG> and the corresponding	  execution of <STRONG>glEnd</STRONG>.     <STRONG>ASSOCIATED</STRONG>	<STRONG>GETS</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_POSITION</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_POSITION_VALID</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_DISTANCE</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_COLOR</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_INDEX</STRONG>	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_RASTER_TEXTURE_COORDS</STRONG>     <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG>	  <STRONG>glBitmap</STRONG>, <STRONG>glCopyPixels</STRONG>, <STRONG>glDrawElements</STRONG>, <STRONG>glDrawPixels</STRONG>,	  <STRONG>glLight</STRONG>, <STRONG>glLightModel</STRONG>, <STRONG>glShadeModel</STRONG>, <STRONG>glTexCoord</STRONG>, <STRONG>glTexGen</STRONG>,	  <STRONG>glVertex</STRONG></PRE></BODY></HTML>
