In this chapter we are going to explore some advanced modeling techniques, mostly suited for curved or wirelike structures that would prove tricky to model as a straight polygon mesh. The techniques covered in Chapter 3 are good for modeling most items, but there are times when a specialist tool makes the job easier. Specifically, we are going to examine
Metaballs/meta objects: Useful for modeling liquid objects like mud
Curves: Useful for modeling wire, especially of the bendable variety
Spin editing: Useful for modeling circular forms
NURBS (nonuniform rational basis spline): Useful for accurate modeling of curved surfaces
Learning these techniques will expand your modeling capabilities in a variety of areas.
