Deforming Surfaces
and Using the Mesh
Modifiers CHAPTER

hen an Editable Poly object is selected, three specific deformation
brushes may be selected in the Paint Deformation rollout. Using IN THIS CHAPTER
W these brushes, you can deform the surface of an object by dragging
over the surface with the selected brush. Using the Paint Deformation
brush
In addition to the editing features available for Editable Mesh and Editable Poly
objects and the Paint Deformation brushes, you also can modify mesh geometries Maintaining primitive objects
using modifiers. The Modifiers menu includes a submenu of modifiers that are with the Edit Mesh and
specific to mesh (and poly) objects. These modifiers are found in the Mesh Editing Edit Poly modifiers
submenu and can be used to enhance the features available for these objects.
Changing mesh geometry
Another set of modifiers that apply specifically to mesh objects are the with modifiers
Subdivision Surface modifiers. These modifiers are also covered in this chapter.
Editing mesh normals

Working with Subdivision
The Basics of Deformation Painting Surfaces
The first thing to remember about the Paint Deformation feature is that it is avail-
able only for Editable Poly objects (or objects with the Edit Poly modifier
applied). When an Editable Poly object is selected, the Paint Deformation rollout
appears at the very bottom of the Command Panel.

Painting deformations
At the top of the Paint Deformation rollout are three buttons used to select the
type of deformation brush to use. These three brushes are the Push/Pull brush,
the Relax brush, and the Revert brush.
When one of these brushes is selected, the mouse cursor changes to a circular
brush, shown in Figure 26.1, that follows the surface of the object as you move
the mouse over the object. A single line points outward from the center of the
circle in the direction of the surface normal. Dragging the mouse affects the sur-
face in a certain manner, depending on the brush that is selected.
