Tessellate Modifier 855
Top: Original mesh object
Lower le ft: Tessellation applied to polygonal facets
Lower right: Tessellation applied to triangu lar faces
Wa rni ng: Tessellating an object retains any UVW
mapping that exists in the stack before the Tessellate
modifier. However, in some c ases, the mapping might
be altered, depending on the type of mapping and the
tessellation settings. Typically, this happens when the
applied mapping uses ex treme compound angles.
Inter face
Parameters rollout
Opera te On—Specifies whether to perform the
tessellationonthetriangularfacesoronthe
polygonal facets (the areas b ound by v isible edges).
Faces—Treats the selection as a set of
triangular faces.
Polygon s—Divides the polygonal facets.
For example, using the polygonal method on the
side of a box results in cross-shaped edges using
theEdgemethod,andX-shapededgesusingthe
Face-Center method.
Edge—Divides the face or polygon from its center
tothemiddleofeachedge. Whenappliedtoa
triangular face, it als o divides unselected faces that
shareedgeswiththeselectedfaces.
Face-Center—Selectthistodividethefacefromthe
center to the vertex corners.
Tens ion—Determines if the new faces are flat,
concave, or convex after Edge tessellation. A
positive value rounds faces by pushing vertices
outward. A negative value creates concave faces
by pulling vertices inward. A setting of 0 keeps
the faces flat. A lso works with the Edge/Polygon
method. Default=25.
Iterations group
Iterations—Specifieshowmanytimesthe
tessellation is applied. For example, setting
Iterations to 2 is similar to clicking the Tessellation
button twice in an editable mesh, except that you
can easily back out at any time while using the
Tessellate modifier. If you want more than four
iterations, apply another Tessellate modifier.
Update Options group
Always—Tessellation is updated whenever the base
geometry changes.
