Chapter 6. Curves and NURBS

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.
