Basics Lesson 4: Beyond the lesson
In this lesson, you completed the construction of the classic temple and learned how to:
 Display objects in template mode.
 Select objects at their component level using selection masks and the right mouse button.
 Assign and edit shading materials for your objects in the scene.
 Access the Attribute editor and view the various node types for objects.

As you proceed through Getting Started with Maya, we assume you are familiar with the fundamental
concepts and skills covered in this first chapter.

Before proceeding to the next chapter you may want to review the material presented in this lesson so
you are familiar with the concepts and skills associated with them. Some suggested tasks you may want
to do on your own:

 Practice construction of additional forms using primitive shapes by creating. additional details for
your temple scene (stairs, roof details, etc.).
 Learn more about the tools and options that have been presented in this lesson, by referring to
the Maya Help. To view the Maya Help, select Help > Maya Help.

Polygon Lessons: Preparing for the lesson
To ensure the lesson works as described, do these steps before beginning:
1. Select File > New Scene to create a new scene.
2. Make sure the Construction History icon (below the menu bar) is on: . (If it is turned off, it has
a large X across it.)
3. Select the Modeling menu set. Unless otherwise noted, the directions in this chapter for making
menu selections assume you've already selected the Modeling menu set.
4. Make sure Display > UI Elements > Help Line is turned on. You will use the Help Line while
modeling.

Polygon Lessons: Introduction

In Maya, modeling refers to the process of creating virtual 3D surfaces for the characters and objects in
the Maya scene. Surfaces play an important role in the overall Maya workflow as they are the items upon
which shading and texture attributes will be assigned. It is these attributes that assist in the creation of
a convincing 3D image. The more accurate you are when modeling your forms in terms of size, shape,
detail, and proportion, the more convincing your final scene will become.

There are three modeling surface types in Maya:
 Polygons
 NURBS
 Subdivision surfaces.

Each surface type has particular characteristics and benefits, and requires specific modeling techniques.
Maya groups the surface modeling tools in a menu set specific to modeling.

Polygon surfaces are a surface type comprised of flat surfaces called faces. You can create a single
polygonal face or a network of polygonal faces called a poly mesh. A poly mesh is comprised of many
faceted three-or-more flat sided polygon faces. When a poly mesh is rendered, it is shaded smoothly so
that the facets are not as apparent in the final image.

Polygonal surfaces can be used to create virtually any type of surface shape and are particularly useful
when simple forms are required. Polygonal surfaces have a wide range of applications and are the
preferred surface type for interactive games and web development applications. Polygonal surfaces are
described with the smallest amount of data, and therefore, can be rendered more quickly, delivering
increased speed and interactive performance to the end user.
