NURBS is based on organic mathematics, which means you can create smooth curves and surfaces. NURBS models can be made of a single surface molded to fit, or they can be a collection of patches connected like a quilt. In any event, NURBS provides ample power for creating smooth surfaces for your models.
Now that you’ve learned the basics of creating and editing poly meshes, you’ll get into creating some organic surfaces using NURBS techniques. This chapter also explains how to use deformers to adjust a model, as opposed to editing the geometry directly as you did with the previous modeling methods.
