Choose one of these seven options to determine
the projection of the vertices.
UseActiveViewport—The vertices are projected
away (inward) from the active viewport.
Recalculate Projection—Recalculates the projection
direction for the currently active viewport.
Because the direction is initially assigned w hen
you pick the Wrap-To object, if you want to change
v iewpor ts after assig n ment, click this button to
recalculate the direction based on the new active
viewport.
Use Any Object’ s Z Ax is—Lets you use the local Z
axis of any object in the scene as a direction. Once
an object is assigned, you can alter the direction of
vertex projection by rotating the direction object.
Pick Z-Ax is Object—Click this button, and then
click the object you want to use to indicate the
direction of the projection source.
Object—Displaysthenameofthedirectionobject.
•
Along V er tex Nor ma ls—Projects the vertices of
the Wrapper object inward along the reverse
direction of its vertex normals. A vertex normal
is a vector produced by averaging the normals
of all faces attached to that vertex. If the
Wrapper object encloses the Wrap-To objec t,
the Wrapper takes on the for m of the Wrap-To
object.
•
Towards Wrapper Center—Projects the vertices
toward the bounding center of the Wrapper
object.
•
Towards Wrapper Pivot—Projects the vert ices
toward the original pivot center of the Wrapper
object.
•
Towards Wrap-To Center—Projects the vertices
toward the bounding center of the Wrap-To
object.
•
Towards the Wrap-To Pivot—Projects the vert ices
towardthepivotcenteroftheWrap-Toobject.
Note: Towards Wrapp er Pivot and Towards the
Wrap-To Pivot operate on the position of the
original pivot point of the object before the
Conform object is created. Once you create the
Conform object, it’s a new compound object with
a single pivot point.
Tip: You can animate the conforming effect by
morphing between the compound object and a
previously made copy of the original wrapper
object. Todothis,however,youmustturnon
Hide Wrap-To Object in the Update group so that
the origi nal object and the compound object have
the same number of vertices. Using this technique,
you can effectively morph between two objects
with a different number of vertices.
Wrapper Parameters group
Provides controls that determine how far the
ver tices are projected.
Default Projection Distance—The distance a ver tex
in th e Wrapper object will move from its original
location if it does not intersect the Wrap-To object.
Standoff Distance—Thedistancemaintained
between the vertex of the Wrapper object and the
surface of the Wr ap-To object. For example, if
you set Standoff Distance to 5, the vertices can be
pushed no closer than 5 units from the surface of
the Wrap-To object.
Use S elected Vert ices—When turned on, only the
selected vertex sub-objects of the Wrapper object
are pushed. When turned off, all vertices in the
object are pushed, regardless of the Modifier stack
