//! @brief C3DPatch handles handles patch object smoothed using a subdivision algorithm
//! @details The patch object subdivision can be modified using C3DPatch::SetLevel / C3DPatch::GetLevel.
//! The sudivided object can be retrieved using C3DPatch::GetFinalObject which is recomputed each time subdivision level changed.
