      Surface::setDiscretizationResolution.
      TriMeshPtr getTriMesh​(boolean forceCopy)
      Create a TriMesh representation of the face.

      This function relies on the resolution set with setMeshResolution.
      The resolution is passed on to Curve::discretizeAdaptive and
      Surface::setDiscretizationResolution.
      boolean isNull()
      checks if the pointer is null
      boolean isShared()
      check if this Ptr has shared ownership or none
      ownership
      OBB obb()
      Create Oriented Bounding Box.

      The default implementation forms a TriMesh in order to estimate the directions for the
      OBB.
      void setMeshResolution​(double resolution)
      Set the resolution used for discretization in the getTriMesh and faceTriMesh
      functions.

      The meaning of this parameter depends on the type of surface.
      Surface surface()
      Get the surface of the face.
      void transform​(Transform3D T)
