Haskellでレンダラーを書いてみるテスト #00
libpolatsk開発に支障がでない範囲でまったりと。
目的
- 挫折中のHaskellをどうにかまともに使えるようにする。
- レンダラーを関数型プログラミング言語で書くことで、関数型プログラミングの(３次元)画像処理用途利用の可能性を探る。
とりあえず命名
nyatr: nyaxt's yet another ray-tracer
環境整備: ghcインストール
MacPortで

からバイナリ版をダウンロード。試す。
tar jxvfp ghc-6.8.2-i386-apple-darwin.tar.bz2 cd ghc-6.8.2 sudo mkdir -p /opt/local/ghc ./configure --prefix=/opt/local/ghc sudo make install
あとは/opt/local/ghcに適当にパスを通す。
