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。
