GL.PushMatrix

Description

Saves both projection and modelview matrices to the matrix stack.

Changing modelview or projection matrices overrides current camera's parameters. These matrices can be saved and restored using GL.PushMatrix and GL.PopMatrix. See Also: PopMatrix 関数

	// Draw a yellow line from the botton left to the
	// top right of the screen
	var mat : Material;

	function OnPostRender() {
		if (!mat) {
			Debug.LogError("Please Assign a material on the inspector");
			return;
		}
		GL.PushMatrix(); // Save the current state
		mat.SetPass(0);
		GL.LoadPixelMatrix();
		GL.Color(Color.yellow);
		GL.Begin(GL.LINES);
		GL.Vertex3(0,0,0);
		GL.Vertex3(Screen.width, Screen.height,0);
		GL.End();
		GL.PopMatrix(); // Pop changes.
