Warp Scalar Filter in ParaView

The Warp Scalar filter uses the VTK filter vtkWarpScalar. The filter moves point coordinates along a vector by a distance determined by a scalar for the active data set.

  1. First the user selects the data they wish to operate on from the Selection Window. It will be highlighted when this occurs.
  2. The user can then select Filter->Alphabetical->Warp (Scalar) from the main menu.
  3. The Scalars menu allows the user to select from various scalars in the data set.
  4. The Scale factor box allows the user to specify the displacement (normal vector times scale factor)
  5. The Normal boxes determine the vector to be used, if the following check box is toggled on. Otherwise the normals array is used.
  6. The Use Normal check box toggles on/off the use of the normal above.
  7. The X-Y Plane check box toggles on/off the use of the Z-values as the scalars. Warping is performed on the Z-axis. This can be used to create carpet plots. Any scalars can then be used to color the output object.
  8. The Apply button must be pressed before the Outline will be generated.
