pymel.core.modeling.rebuildSurface¶

rebuildSurface(*args, **kwargs)¶

This command rebuilds a surface by modifying its parameterization. In some cases the shape of the surface may also change. The rebuildType (-rt) attribute determines how the surface is rebuilt. The optional second surface can be used to specify a reference parameterization.

Flags:

Long Name / Short Name		Argument Types	Properties
caching / cch		bool
	Toggle caching for all attributes so that no recomputation is needed
constructionHistory / ch		bool
	Turn the construction history on or off.
degreeU / du		int
	The degree of the resulting surface in the u direction 0 - maintain current, 1 - linear, 2 - quadratic, 3 - cubic, 5 - quintic, 7 - heptic Default:3
degreeV / dv		int
	The degree of the resulting surface in the v direction 0 - maintain current, 1 - linear, 2 - quadratic, 3 - cubic, 5 - quintic, 7 - heptic Default:3
direction / dir		int
	The direction in which to rebuild: 0 - U, 1 - V, 2 - Both U and V Default:2
endKnots / end		int
	End conditions for the surface 0 - uniform end knots, 1 - multiple end knots, Default:0
fitRebuild / fr		int
	Specify the type of rebuild method to be used: 0 - Convert Classic, the default and original convert method. 1 - Fit using the least squares fit method. 2 - Convert Match, alternate matching convert method. 3 - Convert Grid, uses a grid-based fit algorithm. Default:0
frozen / fzn		bool
keepControlPoints / kcp		bool
	Use the control points of the input surface. This forces uniform parameterization unless rebuildType is 2 (match knots) Default:false
keepCorners / kc		bool
	The corners of the resulting surface will not change from the corners of the input surface. Default:true
keepRange / kr		int
	Determine the parameterization for the resulting surface. 0 - reparameterize the resulting surface from 0 to 1; 1 - keep the original surface parameterization; 2 - reparameterize the result from 0 to number of spans Default:1
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.
noChanges / nc		bool
nodeState / nds		int
	Maya dependency nodes have 6 possible states. The Normal (0), HasNoEffect (1), and Blocking (2)states can be used to alter how the graph is evaluated. The Waiting-Normal (3), Waiting-HasNoEffect (4), Waiting-Blocking (5)are for internal use only. They temporarily shut off parts of the graph during interaction (e.g., manipulation). The understanding is that once the operation is done, the state will be reset appropriately, e.g. Waiting-Blockingwill reset back to Blocking. The Normaland Blockingcases apply to all nodes, while HasNoEffectis node specific; many nodes do not support this option. Plug-ins store state in the MPxNode::stateattribute. Anyone can set it or check this attribute. Additional details about each of these 3 states follow. StateDescriptionNormalThe normal node state. This is the default.HasNoEffectThe HasNoEffectoption (a.k.a. pass-through), is used in cases where there is an operation on an input producing an output of the same data type. Nearly all deformers support this state, as do a few other nodes. As stated earlier, it is not supported by all nodes. Its typical to implement support for the HasNoEffectstate in the nodes compute method and to perform appropriate operations. Plug-ins can also support HasNoEffect. The usual implementation of this state is to copy the input directly to the matching output without applying the algorithm in the node. For deformers, applying this state leaves the input geometry undeformed on the output. BlockingThis is implemented in the depend node base class and applies to all nodes. Blockingis applied during the evaluation phase to connections. An evaluation request to a blocked connection will return as failures, causing the destination plug to retain its current value. Dirty propagation is indirectly affected by this state since blocked connections are never cleaned. When a node is set to Blockingthe behavior is supposed to be the same as if all outgoing connections were broken. As long as nobody requests evaluation of the blocked node directly it wont evaluate after that. Note that a blocked node will still respond to getAttrrequests but a getAttron a downstream node will not reevaluate the blocked node. Setting the root transform of a hierarchy to Blockingwont automatically influence child transforms in the hierarchy. To do this, youd need to explicitly set all child nodes to the Blockingstate. For example, to set all child transforms to Blocking, you could use the following script. import maya.cmds as cmds def blockTree(root): nodesToBlock = [] for node in {child:1 for child in cmds.listRelatives( root, path=True, allDescendents=True )}.keys(): nodesToBlock += cmds.listConnections(node, source=True, destination=True ) for node in {source:1 for source in nodesToBlock}.keys(): cmds.setAttr( ‘%s.nodeState’ % node, 2 ) Applying this script would continue to draw objects but things would not be animated. Default:kdnNormal
object / o		bool
	Create the result, or just the dependency node.
polygon / po		int
	The value of this argument controls the type of the object created by this operation 0: nurbs surface1: polygon (use nurbsToPolygonsPref to set the parameters for the conversion)2: subdivision surface (use nurbsToSubdivPref to set the parameters for the conversion)3: Bezier surface4: subdivision surface solid (use nurbsToSubdivPref to set the parameters for the conversion)
rebuildType / rt		int
	The rebuild type: 0 - uniform, 1 - reduce spans, 2 - match knots, 3 - remove multiple knots, 4 - force non rational 5 - rebuild ends 6 - trim convert (uniform) 7 - into Bezier mesh Default:0
replaceOriginal / rpo		bool
	Create in place(i.e., replace). Flag can have multiple arguments, passed either as a tuple or a list.
spansU / su		int
	The number of spans in the u direction in resulting surface. Used only when rebuildType is 0 - uniform. If 0, keep the same number of spans as the original surface. Default:4
spansV / sv		int
	The number of spans in the v direction in resulting surface. Used only when rebuildType is 0 - uniform. If 0, keep the same number of spans as the original surface. Default:4
tolerance / tol		float
	The tolerance with which to rebuild Default:0.01 Common flags

Derived from mel command maya.cmds.rebuildSurface

Example:

import pymel.core as pm

# rebuild the surface using uniform parameterization
# The rebuilt surface will have 5 spans in u and
# 10 spans in v
pm.rebuildSurface( rt=0, dir=2, su=5, sv=10 )

# rebuild the surface by removing its redundant spans
pm.rebuildSurface( rt=1 )

# rebuild the surface by matching the u parameterization
# of another surface. surface1 is the surface to rebuild
# surface2 is the reference surface
pm.rebuildSurface( 'surface1', 'surface2', rt=2, dir=0 )

# rebuild the surface by removing all multiple interior knots
pm.rebuildSurface( rt=3 )

# rebuild the surface using uniform parameterization
pm.rebuildSurface( rt=4 )
