PathDeform Modifier 755
Parameters rollout
Patch Deform group
Provides controls that let you pick the patch and
adjust the object’s position and deformation along
the gizmo copy of the patch.
Patch—Displays the name of the selected patch
object.
Pick Patch—Click this button, and then select the
patch object you want to use for the deformation.
A gizmo is created for the object that matches
the patch. Once you assign the patch gizmo, you
can adjust the deformation using the remaining
controls in this rollout.
Note: Patch Deform can be used only with a
rectangular quad patch form. The software makes
no distinction between quad-style patches and
certain primiti ve meshes. Examples of suitable
patches are the primitive quad patch object (page
1–994), the primitive c ylinder (page 1–177),and
the primitive torus (page 1–180).(Thecylinder
actually has t ri-patches at each end, but s ince they
are at the end of the list of patches, PatchDeform
just ignores t hese extra faces.)
UPercent—MovestheobjectalongtheU
(horizontal) axis of the gizmo patch, based on a
percentage of the U distance. This spinner defaults
to a s etting of 50 percent, which places the object
atthecenterofthegizmopatch. Asettingof0
percent places the object at the left edge of the
gizmo patch, as seen from the viewport where the
patch was created.
UStretch—Scales the object a long the U
(horizontal) axis of the gizmo patch.
VPercent—Moves the object along the V (vertical)
axis of the gizmo patch, based on a percentage of
the V distance. A setting of 0 percent places the
object at the bottom of the gizmo patch.
VStretch—Scales the object along the V (vertical)
axis of the g izmo patch.
Rotation—Rotates t he modified object w ith respect
to the gizmo patch.
Move To Patch—Clicking this button moves the
object from its original position to the patch object
you are using for deformation. This button is only
available with the PatchDeform (WSM).
Patch D eform Plane group
XY /YZ/ZX—Choose a two-axis plane of the object
to make parallel with the XY plane of the gizmo
patch.
Flip—Reverses the gizmo direction.

using a spline or N U RBS curve as a path. You can
