pymel.core.modeling.smoothTangentSurface

static modeling.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.

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.
