smoothTangentSurface(
surface
, [caching=boolean], [constructionHistory=boolean], [direction=int], [name=string], [nodeState=int], [object=boolean], [parameter=float], [replaceOriginal=boolean], [smoothness=int])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
smoothTangentSurface is undoable, queryable, and editable.
The smoothTangentSurface command smooths the surface along
an isoparm at each parameter value.
The name of the surface is returned and
if history is on, the name of the resulting dependency node is
also returned.
This command only applies to parameter values with a multiple knot
value.
(If the given parameter value has no multiple knot associated
with it, then the dependency node is created but the surface
doesn't change.)
When would you use this? If you have a surface consisting of
a number of Bezier patches or any isoparms with more than a single
knot multiplicity, you could get into a situation where a
tangent break occurs. So, it only makes sense to do this operation
on the knot isoparms, and not anywhere in between, because the
surface is already smooth everywhere in between.
If you have a cubic or higher degree surface, asking for the maximal
smoothness will give you tangent, curvature, etc. up to the degree-1
continuity. Asking for tangent will just give you tangent continuity.
It should be mentioned that this is "C", not "G" continuity we're
talking about, so technically, you can still see visual tangent breaks
if the surface is degenerate.
Note: A single smoothTangentSurface command cannot smooth in both directions
at once; you must use two separate commands to do this.

Properties |
|
direction(d)
|
int
|
  
|
|
Direction in which to smooth knot:
0 - V direction,
1 - U direction
Default: 1
|
|
parameter(p)
|
float
|
|
|
Parameter value(s) where knots are added
Default: 0.0
|
|
smoothness(s)
|
int
|
|
|
Smoothness to get:
0 - Tangent,
1 - Maximum (based on the degree)
Default: 1
|
|
| Common flags |
constructionHistory(ch)
|
boolean
|
|
|
Turn the construction history on or off.
|
|
name(n)
|
string
|
|
|
Sets the name of the newly-created node. If it contains
namespace path, the new node will be created under the
specified namespace; if the namespace does not exist, it
will be created.
|
|
object(o)
|
boolean
|
|
|
Create the result, or just the dependency node.
|
|
replaceOriginal(rpo)
|
boolean
|
|
|
Create "in place" (i.e., replace).
|
|
| Advanced flags |
caching(cch)
|
boolean
|
|
|
Modifies the node caching mode. See the node documentation for more information.
Note: For advanced users only.
|
|
nodeState(nds)
|
int
|
|
|
Modifies the node state. See the node documentation for more information.
Note: For advanced users only.
