Chapter 4: Beginning Polygonal Modeling

Modeling is the process of creating 3D objects, whether for animation or other purposes. Simple objects call for simple models, and complicated objects call for a complex of simple models. One of the toughest decisions is how to represent an object in 3D. Like a sculptor, you analyze the object and deconstruct its design to learn how to create it.

Maya uses three types of modeling: polygons, NURBS, and subdivision surfaces. All three require a process that begins with deciding how best to achieve your design, although it’s common to mix modeling methods in a scene.

To help you decide where to begin, this chapter starts with an overview of modeling, briefly describing the three methods and how they differ. You’ll also learn about Maya’s primitives, which are available with all three modeling methods. The second part of the chapter takes a detailed look at modeling with polygons. (The next two chapters cover the process of modeling with polygons and subdivision surfaces and how to bring them together in one model.)

Topics in this chapter include:

• Planning your model
• Polygon basics
• Poly editing tools
• Putting the tools to use: making a simple hand
• Creating areas of detail on a poly mesh
• Modeling complex objects: the classic steam locomotive
• Suggestions for modeling polygons
