Inter face
Main group
Lets you set the basic parameters for Tur boSmooth.
Iterations—Sets the number of times the mesh is
subdivided. When you increase this value, each
new iteration subdivides the mesh by creating
smoothly interpolated vertices for every vertex,
edge, and face from the iteration before. The
modifier then subdivides the faces to use these
new vertices. Default=1. Range=0 to 10.
From right to left, effect of increasing the number of iterations
Note: B e cautious w hen increasing the number of
iterations. The number of vertices and faces in an
object (and thus the ca lculation time) can increase
as much as four times for each iteration. Applying
four iterations to even a moderately complex
object can take a long time to calculate.
Render I ter (at ion)s —Lets you choose a different
number of smoothing iterations to be applied to the
object at render time. Turn on Render Iters, and
then use the field to its right to set the number of
render iterations.
Isoline Display—When on, the software displays
only is olines: the object’s original edges, b efore
smoothin g. The benefit of using this option is
a less cluttered display. When off, the software
displays all faces added by TurboSmooth; t hus,
higher Iterations values result in a greater number
of lines. Default=off.
Wa rn in g : If you’re going to collapse the model or apply
further modifiers af ter the TurboSmooth, you should
first turn off Isoline Display. Unlike in MeshSmooth,
isoline display is achieved by making all the edges
"invisible," joining large groups of faces together in
single "polygons." This can be esp e cially problematic
if you apply a PolyObject-based modifier afterwards,
because all vertices in the interior o f these "p olygons"
will be lost.
