気に入ったので、色々と作ってみました。
ofxTrueTypeFontUCを使わせてもらっていますので日本語も対応してます。
501 day openFrameworks
[ Video ]
[ About ]
Instagramを中心とした、SNSへの500日連続投稿を達成しました。こんなに続くとは思ってなくて、正確に記録・カウントしていないのでちょっとアバウトですが。抜けは無いはずなので、ズレはあったとしても投稿はしているはず…
当初、500dayという文字で作っていたんですが、リーバイスのジーンズの誕生日が501dayというイベントである事を知り、デニム好きとして、そちらに寄せてみました。背景色もデニム色っぽモノにしてあります。

ofxTrueTypeFontUCからひらがなの文字情報(座標)を取得してNoise関数を掛け合わせてみました。ふよふよしていて面白い。
Twitterで見かけたのですがopenFrameworks0.10.0からUTF8がサポートされるそうです。
openFrameworks, a C++ toolkit for creative coding — UTF8 support
絵文字とか使えるようで、楽しみ。
