最近投稿のタイトルが適当です。
前にわからないって言ってたUV座標の取り方がわかりました。
わからないって言ってたのが馬鹿みたいに簡単にできました。
こんなん。
そういえばちょっと前から作ったものをGoogle App Engineのほうに上げるようにしたんですけど問題なく見られますかね？あまり動作確認とかしてないので・・・
ソースコードはこんな感じ。

UV座標は、
material = new MovieMaterial(mc);
material.interactive = true;
MovieMaterialを使ってinteractiveをtrueにして、
private function onModelMouseDown(e:MouseEvent3D):void {
mc.surface.graphics.beginFill(0xFFFFFF);
mc.surface.graphics.drawCircle(e.uv.u * mc.width, mc.height - (e.uv.v * mc.height), 100);
mc.surface.graphics.endFill();
}MouseEvent3Dのuvで取得できます。
Y座標は「e.uv.v * mc.height」かと思ったんですが、「mc.height - (e.uv.v * mc.height)」でした。
わかりづらいね。

カメラの動きは相変わらずよくわからない。

ドブ板。これは一章ではなくWhat'sシェンムーのです。
それなりに有名なサクラ大戦３のOP。
私はXbox360もVGAでプレイしていて、いちいちディスプレイの裏に行って付け替えるのが面倒なので、一回余計にケーブル噛ませてます。
