Chapter 2. Modeling the Skin of a Biped ... > Creating a Head from NURBS Surfaces

Creating a Head from NURBS Surfaces

One of the most difficult body parts to create with NURBS surfaces is a character’s head. Among other reasons for this difficulty, the head usually has the most recognizable features and requires that multiple openings be created for the mouth, nose, ears, and eyes. Beginning the modeling process by modeling your character’s head with NURBS surfaces will be challenging and will give you a good idea of the strengths and limitations of this surface type. This section introduces you to using NURBS surfaces and shows you how to rough out a specific type of NURBS head from a simple primitive sphere (see Figure 2.2). You are then shown how to manipulate the surface in a variety of ways to create the details of your character’s face, with a special focus on understanding edge placement and surface direction. When you understand how to model the NURBS head successfully, you will be able to apply the same modeling principles to the rest of your character’s body.

2.2. In this section, you learn how to create a NURBS head from a simple sphere (character model by Shawn Rinehart).
