public static int QUADS;

Description

Mode for Begin: draw quads.

Draws quads using each set of 4 vertices passed. If you pass 4 vertices, one quad is drawn, where each vertex becomes one corner of the quad. If you pass 8 vertices, 2 quads will be drawn.

To set up the screen for drawing in 2D, use GL.LoadOrtho or GL.LoadPixelMatrix. To set up the screen for drawing in 3D, use GL.LoadIdentity followed by GL.MultMatrix with the desired transformation matrix.

See Also: GL.Begin, GL.End.
