再帰で立方体 openFrameworks

[ Video ]

[ About ]
昨日の「再帰で四角」を3Dにしてみました。level変数によって高さが決まるので、面積の大きい四角形は高さが低く、面積の小さい四角は高さが高く描写されています。

フレーム数で伸びるようにしたので、ニョキっと感が出て良いと思います。

欠損したボックスの集合体　openFrameworks

[ Video ]

[ About ]
BoxをNoise関数で表示・非表示をコントロールしています。加えて、Boxのサイズも変動するようにしてあるります。

カドケシという消しゴムがありますが、それみたいに見えますね。
