pymel.core.modeling.polySmooth¶

polySmooth(*args, **kwargs)¶

Smooth a polygonal object. This command works on polygonal objects or faces.

Flags:

Long Name / Short Name		Argument Types	Properties
boundaryRule / bnr		int
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed.
constructionHistory / ch		bool
	Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object. Note:If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.
continuity / c		float
	This flag specifies the smoothness parameter. The minimum value of 0.0 specifies that the faces should only be subdivided. Maximum value of 1.0 smooths the faces as much as possible. C: Default is 1.0 Q: When queried, this flag returns a float.
degree / deg		int
divisions / dv		int
	This flag specifies the number of recursive smoothing steps. C: Default is 1. Q: When queried, this flag returns an int.
divisionsPerEdge / dpe		int
frozen / fzn		bool
keepBorder / kb		bool
	If on, the border of the object will not move during smoothing operation. C: Default is on. Q: When queried, this flag returns an int.
keepHardEdge / khe		bool
	If true, vertices on hard edges will not be modified. C: Default is false. Q: When queried, this flag returns a boolean.
keepMapBorders / kmb		int
keepSelectionBorder / ksb		bool
	If true, vertices on border of the selection will not be modified. C: Default is false. Q: When queried, this flag returns a boolean.
keepTesselation / xkt		bool
keepTessellation / kt		bool
	If true, the object will be tessellated consistently at each frame. If false, non-starlike faces will be triangulated before being subdivided, to avoid self- overlapping faces. C: Default is true. Q: When queried, this flag returns a boolean.
method / mth		int
name / n		unicode
	Give a name to the resulting node.
nodeState / nds		int
	Defines how to evaluate the node. 0: Normal1: PassThrough2: Blocking3: Internally disabled. Will return to Normal state when enabled4: Internally disabled. Will return to PassThrough state when enabled5: Internally disabled. Will return to Blocking state when enabledFlag can have multiple arguments, passed either as a tuple or a list.
osdCreaseMethod / ocr		int
	Controls how boundary edges and vertices are interpolated.
osdFvarBoundary / ofb		int
	Controls how boundaries are treated for face-varying data (UVs and Vertex Colors).
osdFvarPropagateCorners / ofc		bool
osdSmoothTriangles / ost		bool
	Apply a special subdivision rule be applied to all triangular faces that was empirically determined to make triangles subdivide more smoothly.
osdVertBoundary / ovb		int
	Controls how boundary edges and vertices are interpolated.
propagateEdgeHardness / peh		bool
	If true, edges which are a result of smoothed edges will be given the same value for their edge hardness. New subdivided edges will always be smooth. C: Default is false. Q: When queried, this flag returns a boolean.
pushStrength / ps		float
roundness / ro		float
smoothUVs / suv		bool
subdivisionLevels / sl		int
subdivisionType / sdt		int
	The subdivision method used for smoothing. C: Default is 0. 0: Maya Catmull-Clark 1: OpenSubdiv Catmull-Clark Common flags

Example:

import pymel.core as pm

pm.polyCube( n='plg1' )
pm.move( -3, 0, 2 )
pm.polyCube( n='plg2' )
pm.move( -3, 0, -2 )
pm.polyCube( n='plg3' )
pm.move( 0, 0, 2 )
pm.delete( 'plg3.f[1]' )
pm.polyCube( n='plg4' )
pm.move( 0, 0, -2 )
pm.delete( 'plg4.f[1]' )
pm.polyCube( n='plg5' )
pm.move( 3, 0, 2 )
pm.polyCube( n='plg6' )
pm.move( 3, 0, -2 )

pm.polyOptions( ao=True, db=1 )

# only one division:
pm.polySmooth( 'plg1.f[0:5]', dv=1 )

# 2 divisions produces a round-ish object
pm.polySmooth( 'plg2.f[0:5]', dv=2 )

# keep border edges
pm.select( 'plg3.f[0:4]' )
pm.polySmooth( kb=1 )

# don't keep border edges
pm.select( 'plg4.f[0:4]' )
pm.polySmooth( kb=0 )

# 1 division, continuity 0.2
pm.select( 'plg5' )
pm.polySmooth( c=0.2 )

# 1 division, continuity 0.8
pm.polySmooth( 'plg6.f[0:5]', c=0.8 )
