## Geometry smoothing

Sometimes visualization operations such as material interface reconstruction can alter mesh surfaces so they are pointy or distorted. The Subset plot provides an optional Geometry smoothing option to smooth out the mesh surfaces so they look better when the plot is visualized. Geometry smoothing is not done by default, you must click the Fast or High radio buttons to enable it. The Fast geometry smoothing setting smooths out the geometry a little while the High setting works produces smoother surfaces.
