[Paraview] End Location of Stream lines obtained with vtkStreamTracer

[Moreland, Kenneth]

There is no direct way to get the end location. However, the stream tracer generates a single polyline cell for each point that it traces. You can look at each polyline cell and get its last point. Then look up the point coordinates in the vtkPoints object. That will be the location of the termination of each stream line.

Note that the stream tracer by default follows streams both forward and backward, and you will get the ends for both.

Subject: [EXTERNAL] [Paraview] End Location of Stream lines obtained with vtkStreamTracer


Dear all,
I was wondering if and how it is possible to access the end location of stream lines obtained with the vtkStreamTracer within a custom vtk class. I found this (http://www.vtk.org/Wiki/VtkStreamTracer) wiki article explaining how one can access the reason for determination of stream lines.
Maybe one can access the end location similarly.
Any help is much appreciated.

Best Regards,
Philipp
