2017年の振り返り

2017年も残り30分ぐらいになりましので、酔った勢いで今年を振り返りかえりましょう。

Creative Cording(笑)を毎日SNSへアウトプットした

あまり「クリエイティブコーディング」という言葉は好きではないのですが、イメージはしやすそうなので。

プログラミングで落書きをした結果を365日アップロードし続けました。
動画と共にソースコードも公開していくスタイルで続けてきました(github中心で10月からこのblogを立ち上げました)

我ながら良くやっていると思います。褒めてください(ﾊﾟﾁﾊﾟﾁ

ソースコードに関しては特別な思いがあったわけでもなく、ただ他の人のプログラミングの動画を模写した時に「ソースコードが公開されていて答え合わせ出来たら楽しいだろうなー」というような意味で上げ始めました。なので、自分のコードを改造したり模写してくれている人の情報を見た時は純粋に楽しいですね。ﾆﾔﾆﾔしてます。

4月頃まではProcessing、それ以降はopenFrameworksになりました。
LeapMotionとかKinectとかリアルタイム制が良い方が都合のいい場合があったので、JAVAよりC++を選んだ結果です。
ただ、JAVA自体が遅いというわけではなく、自分がJAVAをあまり触ったことがないので、早い書き方が出来ないという面も大きいです。

ちなみに、この界隈(?)ではC++敷居が高いと思われていますが、最近のC++は標準ライブラリも開発環境も整備されていますので、悪い選択肢ではないと思います。（簡単とは言っていない）

IAMASっぽいフレンドが増えた

SNSに動画をアップロードしていたのですが、IAMASの在校生・卒業生や、IAMASに将来入りたいなーみたいな事を呟いている友達が増えました。

個人的にはIAMAS(03)で同期だった林さんとTwitterで再開をしたのが衝撃でした(笑
そのほかにも、嫁と同期だったTakawoさんのブログでご紹介を頂いたりして、不思議な縁だなと思います

おわり

とゆーことで残り3分なので、いろいろ書こうと思っていましたが、ここまで。
来年も、みなさまよろしくお願いいたします。
