Subdivision Surface Rollout (Polymesh) 1061
Inter face
Smooth R esul t—Applies t he same smoothing
group to all polygons.
Use NURMS Subdivision—Applies smoothing
via the NURMS method. See NURMS.The
difference b etween NURM S in Editable Poly and
MeshSmooth is that the latter g ives you access to
control vertices, but the former does not.
Youcontrolthedegreeofsmoothingwiththe
I terations controls in the Display and Render
groups.
Note: The remaining controls on this rollout take
effect only when Use NURMS Subdivision is on.
Isoline Display—When on, the software displays
only isolines: the object’s orig inal edges, b efore
smoothing. The benefit of using this option is
a less cluttered display. When off, the software
displays all faces added by NURMS Subdivision;
thus,higherIterationssettings(seeDisplay group
(page 1–1062)) result in a greater number of lines.
Default=on.
Smoothed b ox with Isoline Display o ff (left) and Isoline Display
on (right).
Note: Applying a modifier to an Editable Poly
object cancels the effect of the Isoline Display
option; the wireframe display reverts to showing
allpolygonsintheobject. Thisisnot,however,
always the case with the MeshSmooth modifier.
Most deformation and mapping modifiers
maintain the isoline display, but others, such as the
selection modifiers (except Volume Select) and the
Turn To ... modifiers, c ause the interior edges to
be displayed.
Show Cage—Toggles the display of a two-color
wireframethatshowstheeditablepolyobject
before modificat ion or subdivision. The cage
colors are shown as swatches to the r ight of the
check box. The first color represents unselected
sub-objects, and the second color represents
selected sub-objects. Change a color by clicking
its swatch.
