Methods

allocateArray

Allocate or resize a vtkPoint(name='point'), vtkCellArray (name= 'line'|'poly') or vtkDataArray (name=any) and add it to the vtkPolyData. If allocated, the array is automatically added to the polydata Connects mapper to actor.

Argument	Type	Required	Description
polyData	vtkPolyData	Yes	The polydata to add array to
name	string	Yes	The name of the array to add (special handling for 'point', 'line, 'poly')
numberOfTuples	Number	Yes	The number of tuples to (re)allocate.
dataType	String	Yes	The typed array type name.
numberOfComponents	Number	Yes	The number of components of the array.

connectPipeline

If provided, connects source (dataset or filter) to filter. If provided, connects filter (otherwise source) to mapper If provided, connects glyph as 2nd input to mapper. This is typically for the glyph mapper. Connects mapper to actor.

Argument	Type	Required	Description
pipeline	IWidgetPipeline	Yes	of source, filter, mapper and actor to connect

extend

Method use to decorate a given object (publicAPI+model) with vtkWidgetRepresentation characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	IWidgetRepresentationInitialValues	No	(default: {})

getCoincidentTopologyParameters

Gets the coincident topology parameters applied on the actor mappers

getPixelWorldHeightAtCoord

Argument	Type	Required	Description
worldCoord	Array[Number]	Yes	3D point in world coordinates
displayScaleParams	IDisplayScaleParams	Yes	Display and camera information

getScaleInPixels

Gets wether actors should have a fix size in display coordinates.

newInstance

Method use to create a new instance of vtkWidgetRepresentation

Argument	Type	Required	Description
