NoiseなGear openFrameworks

[ Video ]

[ About ]
15度間隔で直径が変化する変形した円を10個重ねて描写しています。
ガラスの破片だったり、ビル群だったりと色々なものに見えてきて楽しい。

風邪はだいぶ良くなりましたb

Noiseな円をRotate openFrameworks

Noiseでグネグネしている円をひとつ書くごとに回転させてみました。風邪の為、省電力モード(昨日のやつをちょこっと改造しただけ)の投稿になります。

ノイズのトンネル openFrameworks

[ Video ]

[ About ]
Noiseでグネグネしている円をZ軸に並べていっています。シンプルですが、綺麗ですね。

ちょっと風邪ひいて喉がイガイガ。今日は早めに仕事もあがるつもりですが、このまま、悪化すれば、連続更新が途絶えるか
