TextFieldから文字の輪郭を取得して3D上にPixcel3Dで描画
@author yooKo@serialField
@version 1.0.0
Let's Click!
Papervision3DのPixcel3Dでまた遊んだ。
どうぞご自由に画面をClickしてください。
3DdotTextが崩れる様をお楽しみください。
砂の落ち切った後の挙動がおかしいので修正
2009/10/12 21:39 コードの最適化 257行 → 233行になった
233行 → 231行
2009/10/15 2:16
常に new していた箇所を大幅に変更して配列に突っ込んで処理が軽くなったおかげで
複数の文字も表現できるようになった。
231行 → 300行
2009/10/17 8:06
アニメーションしていない時も常にaddPixel3D()するのは好ましくないので
upDate()として切り分けた
