		Vector3 p = camera.ScreenToWorldPoint(new Vector3(100, 100, camera.nearClipPlane));
		Gizmos.color = Color.yellow;
		Gizmos.DrawSphere(p, 0.1F);
	}
}
// Draw a yellow sphere in the scene view at the position
// on the near plane of the selected camera that is
// 100 pixels from lower-left.
//在所选相机的近裁剪面上,绘制一个黄色的球,在左下100像素的位置
function OnDrawGizmosSelected () {
	var p : Vector3 = camera.ScreenToWorldPoint (Vector3 (100,100,camera.nearClipPlane));
	Gizmos.color = Color.yellow;
	Gizmos.DrawSphere (p, 0.1);
