Dif fer ences Between Edit Pol y a nd
Editable Poly
FunctionalityinEditPolyismostlythesameas
that of Editable Poly. Please note the following
differences:
• Edit Poly is a modifier, with all properties
that modifier status entails. These include the
ability to place Edit Poly above a base object
and other modifiers on the stack, to move the
modifier to different lo cations in the stack,
and to apply multiple Edit Poly modifiers to
the same object, each cont aining different
modeling or animation operations.
• Edit Poly has two distinct modes of operation:
Model and Animate. See
Edit Poly Mode
rollout (page 1–624)
.
• Delete Isolated Vertices is now an option on the
Edit Geometry rollout. Previously, it appeared
as a dialog every time you deleted cont iguous
polygons. Now you can set it and forget it.
• Edit Poly eliminates the Full Interactivity
switch; this feature is on all the t i me.
• EditPolyprovidestwonewwaysofobtaining
an existing selection f rom lower in the stack:
Use Stack Selection and Get Stack Selection .
• In add ition to the Settings dialogs from Edit able
Poly, Edit Poly gives you a new Settings dialog
for Align operations, available on the
Edit Poly
Mode rollout (page 1–624)
.
• Edit Poly lacks Editable Poly’s Subdivision
Surface and Subdivision Displacement rollouts.
There are no Weight or Crease sett ings for
ver tices, edges, or borders. If you need to
use Weight and Crease settings, apply a
Meshsmooth modifier (page 1–714) ,set
Iterations to 0, and then make the settings as
desired. Also, there is no provision for setting
vertex properties such as color.
• In Animate mode, you begin a slice operation
by clicking Slice, not Slice Plane. You still need
to click Slice Plane to mov e the plane around.
You can animate t he slice plane.
• In some ca ses, several
Undo (page 1–93)
commands might b e required to revert from
changes made with certain Edit Poly operations,
such as Extrude.
For example, if you extrude a polygon using the
Extrude Polygons dialog (page 1–1073) ,there
will be three Undo actions. The first undoes t he
Commit, w hich happens automatically when
you click the dialog OK button at the end; the
second undoes the change in height (from 0 to
the height you set); and the third undo es the
entry into the Extrude operation.
FollowingisatableshowingtheEditPolyfunctions
that are and are not animatable. Functions that are
not animatable are unavailable in Animate mode.
Functions marked “Yes” can be animated explicitly
in Animate mode.
Functions marked “Proc” cannot be animated
explicitly, but can be animated procedurally. This
means t hey can be applied to different par ts of the
Edit Poly object at different points in the animation
by means of an animated sub-object selection
passed up the stack. For further information, see
