Polygon surfaces are a network of three-or-more sided flat surfaces called faces
that get connected together to create a poly mesh. Polygon meshes are
comprised of vertices, faces, and edges.
The wireframe lines on the mesh represent the edges of each face. The regions
bounded by the edges are faces. Where the edges intersect each other is the
location of a point called a vertex.
When a polygon mesh is rendered, its edges can be set to appear hard or
smooth. As a result, polygons can easily represent both flat as well as curved
3D forms. You’ll work with these component types continuously when
modeling with polygons.
Polygonal surfaces have a wide range of applications and are the preferred
surface type for many 3D applications including interactive games and web
development applications.
Polygonal surfaces can be described with the smallest amount of data of all
the 3D surface types, and therefore, can be rendered quickly, delivering
increased speed and interactive performance to the end user in games and
other applications.
Preparing for the lesson
To ensure the lesson works as described, do these steps before beginning:
1 Select File > New Scene.
2 Make sure Construction History (below the menu bar) is on:
. (If
it is turned off, the icon has a large X across it).
3 Select the Polygons menu set.
Unless otherwise noted, the directions in this chapter for making menu
selections assume you’ve already selected the Polygons menu set.
4 Make sure Display > UI Elements > Help Line is turned on.
You will use the Help Line while modeling.
5 If you have not already done so, copy the GettingStarted folder from
its installation location to your projects directory. Then, set the
GettingStarted directory as your Maya project. For more information,
see Copying and setting the Maya project on page 25.
