Yes I see now the influence of the number of seed points is substantial.
I have tried to use the Mask Points function (which can reduce the # of points??) in the workflow;
- celldata.vtu
- CellDatatoPointData
- Mask Points
- StreamTracerWithCustomSource
- Not sure of the flow here, do you select input source as CellDatatoPointData or MaskPoints?
- And also do you select Seed Source as your custom seeding surface?
