円周を結ぶライン openFrameworks

[ Video ]

[ About ]
円周上の2点を結ぶ線が85(255 / 3)本あります。また、線の濃さ(Alpha)はそれぞれ違っています。線が無い場所でも円の輪郭が見えてくる気がして面白いですね。

Remake_20170312 openFrameworks

[ Video ]

[ About ]
去年の今頃にInstagramに投稿した動画をリメイクしてみました。当時はProcessingを使って作っていたので、openFrameworksで作り直した形になります(実装の仕方は変えてありますが)。

一年前のコードを改めてみましたが、どことなく探り探りやっているのが分かりますね(笑)。Linkの方にGitHubへのリンクを並べておくので、興味ある方は見比べてみて頂いても面白いかも。

ギア・ギア・ギア openFrameworks

[ Video ]

[ About ]
なぜか気分的にギアが作りたくなったので。ギア同士が食い込んでしまっているので、本当は、なだらかな角度をつけてあげないとダメっぽいですね。調べたらどの程度の角度とか出てきそうですが、そこまでの熱はなかったので、ここまで。
