The elements of a two-element	array are <EM>x</EM>	       and <EM>y</EM>; of a three-element array,	<EM>x</EM>, <EM>y</EM>, and <EM>z</EM>; and of a	       four-element array, <EM>x</EM>, <EM>y</EM>, <EM>z</EM>, and	<EM>w</EM>.     <STRONG>DESCRIPTION</STRONG>	  <STRONG>fglVertex</STRONG> commands are used within <STRONG>fglBegin</STRONG>/<STRONG>fglEnd</STRONG> pairs to	  specify point, line, and polygon vertices.  The current	  color, normal, and texture coordinates are associated	with	  the vertex when <STRONG>fglVertex</STRONG> is called.	  When only <EM>x</EM> and <EM>y</EM> are	specified, <EM>z</EM> defaults to 0 and <EM>w</EM>	  defaults to 1.  When <EM>x</EM>, <EM>y</EM>, and <EM>z</EM> are specified, <EM>w</EM> defaults	  to 1.     <STRONG>NOTES</STRONG>	  Invoking <STRONG>fglVertex</STRONG> outside of	a <STRONG>fglBegin</STRONG>/<STRONG>fglEnd</STRONG> pair results	  in undefined behavior.     <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG>	  <STRONG>fglBegin</STRONG>, <STRONG>fglCallList</STRONG>, <STRONG>fglColor</STRONG>, <STRONG>fglEdgeFlag</STRONG>,	<STRONG>fglEvalCoord</STRONG>,	  <STRONG>fglIndex</STRONG>, <STRONG>fglMaterial</STRONG>,	  <STRONG>fglNormal</STRONG>, <STRONG>fglRect</STRONG>, <STRONG>fglTexCoord</STRONG>, <STRONG>fglVertexPointer</STRONG></PRE></BODY></HTML>
