pymel.core.animation.poleVectorConstraint¶

poleVectorConstraint(*args, **kwargs)¶

Constrains the poleVector of an ikRPsolve handle to point at a target object or at the average position of a number of targets. An poleVectorConstraint takes as input one or more targetDAG transform nodes at which to aim pole vector for an IK handle using the rotate plane solver. The pole vector is adjust such that the in weighted average of the world space position target objects lies is the rotate planeof the handle.

Maya Bug Fix:

• when queried, angle offsets would be returned in radians, not current angle unit

Modifications:

• added new syntax for querying the weight of a target object, by passing the constraint first:

  aimConstraint( 'pCube1_aimConstraint1', q=1, weight ='pSphere1' )
  aimConstraint( 'pCube1_aimConstraint1', q=1, weight =['pSphere1', 'pCylinder1'] )
  aimConstraint( 'pCube1_aimConstraint1', q=1, weight =[] )
  

Flags:

Long Name / Short Name		Argument Types	Properties
layer / l		unicode
	Specify the name of the animation layer where the constraint should be added.
name / n		unicode
	Sets the name of the constraint node to the specified name. Default name is constrainedObjectName_constraintType
remove / rm		bool
	removes the listed target(s) from the constraint.
targetList / tl		bool
	Return the list of target objects.
weight / w		float
	Sets the weight value for the specified target(s). If not given at creation time, the default value of 1.0 is used.
weightAliasList / wal		bool
	Returns the names of the attributes that control the weight of the target objects. Aliases are returned in the same order as the targets are returned by the targetList flag Flag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.poleVectorConstraint

Example:

import pymel.core as pm

# aims the pole vector of handle1 at cone1.
pm.poleVectorConstraint( 'cone1', 'handle1' )

# uses the average of the position of cone1 and surf2.
pm.poleVectorConstraint( 'cone1', 'surf2', 'handle2', w=.1 )

# sets the weight for cone1's effect on handle2's poleVector to 10.
pm.poleVectorConstraint( 'cone1', 'handle2', e=True, w=10. )

# removes surf2 from handle2's poleVectorConstraint.
pm.poleVectorConstraint( 'surf2', 'handle2', e=True, rm=True )

# adds surf3 to handle2's poleVectorConstraint with the default weight.
pm.poleVectorConstraint( 'surf3', 'handle2' )
