Stream Tracer with Point Source seed does often not work for 2-D data
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Try this:
- Create plane from Sources menu
- Apply filter "Random vectors"
- Apply filter "Stream Tracer"
- set the vectors to "BrownianVectors" Result: you see nothing.
-
increase the number of points or the radius Result: in most cases you still see nothing.
-
change seed type to "line source" (default diagonal line) Result: visible stream lines.
The same happens when starting with a box source and applying a slice filter first. (If you prefer to test it with "real" data, use the vtk file from bug 7395.)
