rollout change the apparent surface tension by
moving vertices closer to, or away from, their
neighbors. The typical result is that the object gets
smoother and a little smaller as the vertices move
toward an averaged center point. You can see the
most pronounced effects on objects with shar p
corners and edges.
Relax—Turnsontherelaxfunctionforrenderings.
Relax V iewports—Turns on t he relax funct ion for
viewports.
Relax Value—Sets the distance a vertex moves as a
percentage of the distance between a vertex and
the average location of its neighbors. Range=-1.0
to 1.0. Default=0.5.
Iterations—SetshowmanytimesRelaxisrepeated.
Each iteration recalculates average vertex locations
based on the result of the previous iteration.
Default=1.
Keep Boundary Points Fixed—Ve r t i c e s at t h e e d g e
of open patches do not relax. Default=on.
Save Outer Corners—Preserves the original
positions of vertices farthest away from the object
center.

Procedures
To tra nsform either ver tices or vectors :
1.
At Patch (Vertex) level, with Selection rollout >
Filter group > Vertices turned on, select vert ices
in the patch object yo u want to transform.
Vertices and their vectors both appear.
2. Turn off one of the filters, leaving the other on,
and choose a t r ansform.
A transform cursor appears when you move
onto a vertex or vector in the selection set.
You can toggle between filters to alternatively
transform either component.
To switch vertex ty pes:
1.
Right-click a patch vertex.
