public static int LINES ;


線(Line)描画の Begin モード

Draws lines between each pair of vertices passed. If you pass four vertices, A, B, C and D, two lines are drawn: one between A and B, and one between C and D.

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.
