Gelatoでは、デフォルトで持っている基本図形は球体だけ。後はInputフォルダにあるティーポットなどのアーカイブのみ。

ということで、MayaのデフォルトのNurbsサーフェイスをrib exportしてみた。まず、注意しなければならないのは、そのままではつかえないこと。
WorldBegin〜EndやObjectBeginステートメント、Perspectiveなどはすべて削除。オブジェクトのみ。Nupatchだけにした。当然、原点で作成している。たとえば、円錐Coneは、次のようになる。
ファイル名はcone.ribとした。なお、gelatoでribを読み込むには
RMRからlibをダウンロードする必要がある。
