A ruler for drawing panoramic perspective. The rough difference between type 1 and 1 is whether or not the concept of infinity (vanishing point) or not, in the real world, parallel lines are parallel to each other, so there is no such thing as a point of intersection, but personally it is recommended to use two frankly for drawing. パノラマパース描画用の定規。タイプ1・2の大雑把な違いは無限遠の概念(消失点)があるかないかだが、現実世界では平行線はどこまで行っても平行で交わって点になるなんて事は無いので個人的には2推奨だが、ぶっちゃけ描画に使う分には大差無い。
