.FBXを読み込んでみる1(解析編)

.FBX　を読み込んで表示できると便利です。
.FBX　は　Autodesk　社の製品の中間ファイルフォーマットです。
3ds Max , Maya , MotionBuilder , Mudbox , Softimage 間のデータを
受け渡す時のために作られました。
その後、Lightwave 3D　や　CINEMA 4D　や　Shade　でも使えるようになりました。
FBXはバージョンによってファイルの内容が違います。
一般的に使用するには FBX SDK　を使うのが良いです。

解析編という事で一応中身を見ておきます。
例によってメタセコイアを使います。
http://horsetail.sakura.ne.jp/index.html
こちらのサイトに　FBXエクスポーター　というプラグインがあるのでインストールします。
そしてメタセコイアで立方体を作って四角形面を三角形面にし、FBXエクスポーター　で
出力します。
その際は、 ASCII　形式で保存します。

このようになりました。
非常に冗長かつ、一見、必要なさそうな記述が大量にあります。
これは異なるソフト間でなるべくデータの互換性を高めるためのものです。
頑張れば、ASCII形式のパーサーを作る事もできるかもしれませんが
バージョン間の違いなどに対応するのは面倒なので素直に　FBX SDK　を使いましょう。
では次回の読み込み編で読み込んでみます。
