The	  base of the cylinder is placed at <EM>z</EM> =	0, and the top at	  z=height. Like a sphere, a cylinder is subdivided around the	  <EM>z</EM> axis into slices, and along	the <EM>z</EM> axis into	stacks.	  Note that if <EM>top</EM> is set to 0.0, this routine generates a	  cone.	  If the orientation is	set to <STRONG>GLU_OUTSIDE</STRONG> (with	  <STRONG>fgluQuadricOrientation</STRONG>), then	any generated normals point	  away from the	<EM>z</EM> axis.	Otherwise, they	point toward the <EM>z</EM>	  axis.	  If texturing is turned on (with <STRONG>fgluQuadricTexture</STRONG>), then	  texture coordinates are generated so that <EM>t</EM> ranges linearly	  from 0.0 at <EM>z</EM>	= 0 to 1.0 at <EM>z</EM>	= <EM>height</EM>, and <EM>s</EM>	ranges from	  0.0 at the +<EM>y</EM>	axis, to 0.25 at the +<EM>x</EM>	axis, to 0.5 at	the -<EM>y</EM>	  axis,	to 0.75	at the -<EM>x</EM> axis,	and back to 1.0	at the +<EM>y</EM>	  axis.     <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG>	  <STRONG>fgluDisk</STRONG>, <STRONG>fgluNewQuadric</STRONG>, <STRONG>fgluPartialDisk</STRONG>,	  <STRONG>fgluQuadricTexture</STRONG>, <STRONG>fgluSphere</STRONG></PRE></BODY></HTML>
