Play with Waterdrop (激重 注意！)
<< 水滴遊び >> ※注：激重
別のものを作ろうと MetaBall系の作品やPixelBender系の作品を手当たり次第に見ていた際に
実装方法を思いついて作ってみました。 (＋iPhone OS4のデモ画面で良く出てくる水滴壁紙も)
個別の作品名は書ききれませんが、皆さんありがとうございます。
PixelBenderはある程度複雑になると、処理が間に合わないのか表示が点滅する場合があるようです。
開発環境では一応、点滅しないところまでは持っていけましたが、問題あるようならコメントをください。
試行錯誤でかなり長いPixelBenderのコードになってしまいました。ある程度は標準のフィルターで
置き換えられるのかもしれませんが・・・
水滴の上にマウスをもっていくと水滴が引き寄せられます。 飽きるまで水滴を誘導して遊んでください。
誘導が歯がゆい場合は、マウスで強制ドラッグもできます。
操作： マウス移動 = 誘導
ドラッグ = 強制誘導
クリック = しずくが少しずり落ちます。 ガラス窓を叩くイメージ
ダブルクリック = しずく再生成
SHIFT+マウス移動 = ライト位置変更
Zキー = デバッグ表示
Xキー = 透明感OFF
オプション： SIMPLE = 背景をシンプルなグラデーションにします。こちらのほうが綺麗かも
AUTO = ぼーっと見るためのモード。
