700 Chapter 8: Modifiers
Object resulting from 270-de gree lathe
Weld Core —Simplifies the mesh by welding
together vertices that lie on the axis of revolution.
K eep it turned off if you intend to create morph
targets.
Flip Normals—Dependingonthedirectionof
the vertices on your shape, and the direction of
rotation, the lathed object mig ht be inside out.
Toggle the Flip Normals check box to fix this.
Segments—Determineshowmanyinterpolated
segments are created in the surface between
the start and endpoint. This p arameter is als o
animatable. Default=16
Note: You can create up to 10,000 segments using
the segments spinner. Try not to create geometry
that is more complex than you need. O ften you can
get s atisfactory results by using smoothing groups
or smoothing modifiers, r ather than increasing
segmentation.
Capping group
Controls whether or not caps are created for the
interior of the lathed object if Degrees is set to less
than 360.
Cap Start—Caps the star t of the lathed object with
Degrees set to less than 360 and a closed shape.
Cap End—Capstheendofthelathedobjectwith
Degrees set to less than 360 and a closed shape.
Morph—Arranges cap faces in a predictable,
repeatable p attern necessary for creating m or ph
targets. Morph capping can generate long, thin
faces that don’t render or deform as well as grid
capping. Use morph capping primarily if you are
lathing multiple morph targets.
Gri d—Arranges cap faces in a square grid trimmed
at the shape boundar ies. This method produces
a sur face of evenly sized faces that can easily be
deformed by other modifiers.
Direction group
Sets up the direction of the axis of revolution,
relative to the pivot point of the object.
X/Y /Z—Set the direction of the axis of revolution
relative to the pivot point of the object.
Align group
Min/Center /Max—Align the axis of revolution to
the minimum, center, or maximum extents of the
shape.
Output group
Pat ch—Produces an object that you can collapse to
a patch object (see
Editing the Stack (page 1–489) ).
Mesh—Produces an object that you can collapse to
a m esh object (see
Editing the Stack (page 1–489) ).
NUR B S —Produces an object that can b e collapsed
to a NURBS surface (see
Editing the Stack (p age
1–489)
).
Generate Mapping Coordinates—Applies mapping
coordinates to the lathed object. When Deg rees is
less than 360, and Generate Mapping C o ordinates
is turned on, additional mapping coordinates are
appliedtotheendcaps,placinga1x1tileoneach
cap.
Real-World M ap Size—Cont rols the scaling
method used for texture mapped materials that
areappliedtotheobject.Thescalingvaluesare
