GL.QUADS

説明

四角形(Quad)描画の Begin モード

スクリーン空間に 2D の何かを描画したい場合、 probably you will want to use GL.LoadOrtho or GL.LoadPixelMatrix.
"3D" の場合は、実際の 3D 変換の GL.MultMatrix に続けて GL.LoadIdentity の使用を 検討してください。

See Also: GL.Begin, GL.End.

	// Draw red a rombus on the screen
	// and also draw a small cyan Quad in the left corner
	var mat : Material;
	function OnPostRender() {
		if (!mat) {
			Debug.LogError("Please Assign a material on the inspector");
			return;
		}
		GL.PushMatrix();
		mat.SetPass(0);
		GL.LoadOrtho();
		GL.Begin(GL.QUADS);
		GL.Color(Color.red);
		GL.Vertex3(0,0.5,0);
		GL.Vertex3(0.5,1,0);
		GL.Vertex3(1,0.5,0);
		GL.Vertex3(0.5,0,0);

		GL.Color(Color.cyan);
		GL.Vertex3(0,0,0);
		GL.Vertex3(0,0.25,0);
		GL.Vertex3(0.25,0.25,0);
		GL.Vertex3(0.25,0,0);
		GL.End();
		GL.PopMatrix();
