Hi, I explored it a little bit and get results like this:

1\> I first execute the stream tracer filter and get output, this is a [program based on cpp](https://github.com/wangzhezhe/5MCST/blob/master/vtk_example/streamline/streamline_exampleKitchen.cpp), maybe it easier to use python to do that. In fact, executing stream tracer filter through the paraview interface can also get similar output. It is unnecessary to use extra program to do that.

2\> There is a cell field called SeedIds in the output dataset, when using the vtk finder view, we can select specific streamline as needed.

3\> After extracting selected results, we can get dedicated results, maybe we can output these points coordinates for subsequent analysis.
