Creasing and hardening edges on a mesh
Lesson 1: Modeling a polygonal mesh
NURBS Modeling
Beyond the lesson
In this lesson you learned some basic techniques
of polygonal modeling:
- You
can create complex polygonal models with surprisingly few techniques.
- Starting
from a primitive surface such as a cube, you can smooth, scale, move,
extrude, split, and rotate components of the primitive to create
a low resolution version of the model you want to create.
- You
must frequently adjust vertices to fine-tune the shape, and finally smooth
the edges between faces where desired in order to produce the final
version of your model.
- Another
method for previewing a smoothed version of the mesh before it is
smoothed is via Smooth Mesh Preview. Press
the 2 or 3 key while the mesh is selected to preview it in a smoothed
state. Press the 1 key to return it to the unsmoothed state.
Polygonal modeling has many timesaving features
not covered in this lesson:
- For example, Boolean operations (union, difference,
and intersection) are a common way to create a new object from the
interaction of two existing objects.
- If
you’re planning to use your polygonal surfaces where the poly count
is constrained, such as with interactive games, Maya has a number
of tools for minimizing the number of polygonal faces of an object
such as the Reduce Tool. Fewer faces means
simpler geometry. This is critical when fewer polygons means increased
interactive performance with games applications. You can view the
polygon count on your mesh by selecting the mesh and then choosing
Poly Count.
- Maya
also has a category of tools called Deformers. Deformers
let you bend, twist, and scale your objects by enveloping the object
in a cage-like manipulator called a lattice deformer that
you can manipulate.
- The
NURBS chapter in this guide describes how to use the Sculpt
Geometry Tool to modify a surface by pushing, pulling,
and smoothing a surface without first selecting vertices. Though
the lesson shows how to shape a NURBS surface, you can apply many
of the same techniques when sculpting polygonal surfaces.
- You can also modify a polygon mesh
using the Soft Modification Tool which
lets you smoothly modify a group of vertices on a mesh.
