扇スタイル　openFrameworks

[ Video ]

[ About ]
Twitterでフォローしている独楽回しeddyさん(@EKey2210)の投稿からインスパイアさせて頂きました。

扇の円弧の部分だけ線をつけるのがサイバー感を際立たせていてカッコいい。

openFrameworksでUTF8(絵文字)を使う

[ Video ]

[ About ]
ofTrueTypeFontで絵文字(Emoji?)を表示。FontSizeを32以上にするとdrawString呼んでも描写してくれない現象に遭遇してドハマりしました…

なお、絵文字の選考基準は「ひと夏の恋」です。
ご精査下さい。

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。
