openFrameworksでUTF8を使う

[ Video ]

[ About ]
openFrameworks0.10.0からUTF8がサポートされたという事なので、ofTrueTypeFontで日本語を表示してみました

「ソースの文字コードをUTF8にすれば大丈夫だろ」ぐらいのお手軽感覚でいたのですが、なかなか表示してくれず…文字列リテラルの前にu8プレフィックスをつけてあげたら上手く文字列が渡ってくれました。

環境はWindows, Visual Studio 2017です。

あいうえお表 ofxTrueTypeFontUC openFrameworks

[ Video ]

[ About ]
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。
