GL.Viewport

パラメーター

説明

レンダリングビューポートを設定します。

すべてのレンダリングは渡された pixelRect の内部に限られます。 ビューポートを変更した場合、内部のすべてのレンダリングされたコンテンツが引き伸ばされます。

	// Draw a red Quad that covers all the view port, and the when space is pressed
	// the viewport gets expanded to the whole screen and stretch the contents inside
	var mat : Material;
	private var stretch : boolean = false;

	function Update() {
		if(Input.GetKeyDown(KeyCode.Space)) {
			if(stretch) {
				stretch = false;
			} else {
				stretch = true;
			}
		}
	}

	function OnPostRender() {
		if (!mat) {
			Debug.LogError("Please Assign a material on the inspector");
			return;
		}
		GL.PushMatrix();
		mat.SetPass(0);
		GL.LoadPixelMatrix();
		if(stretch) {
			GL.Viewport(Rect(0,0,Screen.width,Screen.height));
		} else {
			GL.Viewport(Rect(0,0,Screen.width/2,Screen.height));
		}
		GL.Color(Color.red);
		GL.Begin(GL.QUADS);
		GL.Vertex3(0,0,0);
		GL.Vertex3(0,Screen.height,0);
		GL.Vertex3(Screen.width,Screen.height,0);
		GL.Vertex3(Screen.width,0,0);
		GL.Color(Color.yellow);
		GL.End();
		GL.Begin(GL.TRIANGLES);
		GL.Vertex3(Screen.width/2,Screen.height/4,1);
		GL.Vertex3(Screen.width/4,Screen.height/2,1);
		GL.Vertex3(Screen.width - Screen.width/4,Screen.height/2,1);
		GL.End();
		GL.PopMatrix();
	}
