Description

スクリーンの点を通してカメラからカメラからレイを通します。

結果として得られたレイはワールド空間でカメラの近平面から始まり スクリーンの位置(x,y)ピクセル座標に向けて向かいます。(position.zは無視されます。) スクリーンスペースはピクセルで定義されています。左下の画面が(0,0)、右上が(pixelWidth,pixelHeight)です。

	// Draws a line in the scene view going through a point 200 pixels
	// from the lower-left corner of the screen
	function Update () {
		var ray : Ray = camera.ScreenPointToRay (Vector3(200,200,0));
		Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
	}
