Warp By Vector

This filter displaces point coordinates along a vector attribute. It is useful for showing mechanical deformation.

The Warp (vector) filter translates the points of the input dataset using a specified vector array. The vector array chosen specifies a vector per point in the input. Each point is translated along its vector by a given scale factor. This filter operates on polygonal, curvilinear, and unstructured grid datasets. Because this filter only changes the positions of the points, the output dataset type is the same as that of the input.

Property Description Default(s) Restrictions
Input This property specifies the input to the Warp (vector) filter.  

Accepts input of following types:

  • vtkPointSet
  • vtkImageData
  • vtkRectilinearGrid

The dataset must contain a field array (point) with 3 component(s).
Vectors The value of this property contains the name of the vector array by which to warp the dataset's point coordinates.  

An array of vectors is required.
ScaleFactor Each component of the selected vector array will be multiplied by the value of this property before being used to compute new point coordinates. 1.0
