Image Mesh Generator

画像をメッシュ化するTOOLです。
とある目的の為に作成しましたw

アウトライン作成 ->メッシュ作成の為のアウトラインを作成します。
・頂点作成;画像上クリック。
・アウトライン作成の終了(アウトラインを閉じる):始点を再度クリック。
・頂点を追加:アウトライン上をクリック
・頂点を削除:SHIFTキーを押しながら、頂点をクリック
・頂点の移動:閉じたアウトラインの頂点をドラッグ

・線を交差させると、正しくMeshが作成できません

メッシュ化 -> アウトラインをメッシュ化します。
・アウトラインの周りの矩形上の8つの点をクリックする事で、
 メッシュ化の為の基準点を変更できます。(メッシュ化の前に選択)
・基準点によって、メッシュの区切り方が変化します。
・キーボードダウン(何でも可)でメッシュが確認できます。
・メッシュ化した画像はドラッグで動かせます。(頂点移動も可)

メッシュ解除 -> 作成したメッシュをアウトラインに戻します。

書き出し -> 頂点情報をXMLに書き出します。

画像の変更 -> 画像が変更できます。HTTP経由での指定もできますが、crossdomainエラーが出るので、アップロードでw
需要があれば直します。
