Hello, I am trying to use the StreamTracer with custom source on my dataset, but my Dataset has 100,000,000 cells.
First StreamTracer with custom source is not active on cell data so I had to convert using "Cell Data to Point Data" filter. Then, as my dataset is so big, I can not apply the "StreamTracer with custom source " directly on top of "CellDataToPointData" filter, so I tried to use "MaskPoints" to reduce the number of points to 5000 and then apply the filter. I am trying to draw the velocity field in a cube. The velocity vector array seems to have passed to the Mask Point as I check in the Information tab of the Mask Point filter, but then I don´t see any thing. I have also checked the following in the Mask Point filter: 1. Proportionally Distribute maximum number of Points 2.Random Sampling 3. Generate Vertices 4. Single Vertex per Cell In the MaskPoints I can see the 5000 Points created if I switch to the Point View. Also in the StreamTracer I am using all the defaults. I tried changing the Maximum Steps, but it didn´t have any effect. Could anybody please tell me what is my error in this procedure? Thanks a lot
