pymel.core.modeling.smoothTangentSurface¶

smoothTangentSurface(*args, **kwargs)¶

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 Gcontinuity 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.

Flags:

Long Name / Short Name		Argument Types	Properties
caching / cch		bool
	Modifies the node caching mode. See the node documentation for more information. Note:For advanced users only.
constructionHistory / ch		bool
	Turn the construction history on or off.
direction / d		int
	Direction in which to smooth knot: 0 - V direction, 1 - U direction Default:1
frozen / fzn		bool
name / n		unicode
	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.
nodeState / nds		int
	Modifies the node state. See the node documentation for more information. Note:For advanced users only. Flag can have multiple arguments, passed either as a tuple or a list.
object / o		bool
	Create the result, or just the dependency node.
parameter / p		float
	Parameter value(s) where knots are added Default:0.0
replaceOriginal / rpo		bool
	Create in place(i.e., replace). Advanced flags
smoothness / s		int
	Smoothness to get: 0 - Tangent, 1 - Maximum (based on the degree) Default:1 Common flags

Derived from mel command maya.cmds.smoothTangentSurface

Example:

import pymel.core as pm

pm.smoothTangentSurface( 'surface1', ch=True, p=0.3, d=0 )
pm.smoothTangentSurface( 'surface1.v[0.3]', ch=True )
# Smoothes surface1 along parameter value v = 0.3. When the
# isoparm is specified, the direction and parameter value is
# implied and the "p" and "d" flags can be omitted.

pm.smoothTangentSurface( 'surface1', ch= True, p= (0.3, 0.5, 0.8), nk=2, d=0 )
# Smoothes along parameter values v = 0.3, 0.5 and 0.8.
