200度の四角を沢山書く openFrameworks

[ Video ]

[ About ]
200度の四角形を書いて、以前作成したねじれC openFrameworksの方法でズラシてみました。

この一部が欠けた四角形を描写するロジック、スマートな方法が思いつかずドロ臭い方法で実装となりました。無念。

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。
