v	Specifies a pointer to an array of two, three, or four elements. The elements of a two-element array are x and y; of a three-element array, x, y, and z; and of a four-element array, x, y, z, and w.

 glVertex commands are used within  glBegin/ glEnd pairs to specify point, line, and polygon vertices. The current color, normal, and texture coordinates are associated with the vertex when  glVertex is called.

When only x and y are specified, z defaults to 0 and w defaults to 1. When x, y, and z are specified, w defaults to 1.

Invoking  glVertex outside of a  glBegin/ glEnd pair results in undefined behavior.

 glBegin(3G),  glCallList(3G),  glColor(3G),  glEdgeFlag(3G),  glEvalCoord(3G),  glIndex(3G),  glMaterial(3G),
 glNormal(3G),  glRect(3G),  glTexCoord(3G),  glVertexPointer(3G)
