Figure 4.6 - Different levels of subdivision

With the Quality value, you can control the accuracy of how your

modifier will place the vertices concerning the original object. Higher

values will result in more precision locations but will add more

computational load to the model.

4.2.1 Controlling surface smoothing

Even after using the Subdivision Surface modifier in a model, you might

still see a few faces showing up. The modifier helps to create a smooth

surface for the model, but won't remove visible borders from the faces it

creates (Figure 4.7).
