virtual bool MBMesquite::RefSizeTargetCalculator::have_surface_orient ( ) const [inline, virtual]

Use 3x2 W for surface elements if true, 2x2 W if false.

If true, then the targets for surface elements attempt some control of orientation and therefore get_surface_target must be used to get the targets. If false, then the target contains no orientation data and is therefore the same as the corresponding 2D target for surface elements. In this case, get_2D_target should be used.
