[Paraview] Find the intersection point between a connectivity and a stream tracer

Fri Jun 8 06:22:29 EDT 2018

Dear Cory,
Can you send me the state through which you got the image.
Your filter creates errors in my case, I would like to know if it's a problem of my mesh or I'm using it the wrong way ...

Best Regards,
Andrea

Thank you Cory for the answer,
Your idea works also if I have, instead of a slice, only a portion of a slice (I cut slices portions thanks to the connectivity filter)?

No, my solution is for the special case of a plane. For your case, please see my tip on our Discourse forum that will explain how to do this for your portion of a slice: https://discourse.paraview.org/t/compute-the-signed-distance-field-from-a-polygonal-mesh/123

Once you have followed the steps in the tip, apply a Contour filter to the output of the Programmable Filter. Set the isovalue to 0 and the Contour By property to Distance. The output will consist of your intersection points. See the attached image where I have done this. The red spheres show the intersection points.

HTH,
Cory

In the image attached, I have created a connectivity (in blue) of a slice and a streamline in red that crosses it.

Best Regards,
Andrea

Andrea,

In fact, you can use the Slice filter itself to compute the intersection of streamlines with a plane. Just apply a Slice filter to your StreamTracer output, align the Slice with your desired plane, and you will get the intersection points.

See the attached image that shows stream tracer output, the plane widget from the Slice filter (red rectangle), and the intersection points depicted with blue spherical glyphs.

HTH,
Cory

Does anyone have an idea on how to deal with this problem?
Does Paraview have no tools to easily find a point of intersection between plan and line?

Best Regards,
Andrea

Dear Users,
I need to find the intersection point between a connectivity surface (portion of a slice) and a stream tracer that runs through this.
I have tried the IntersectFragments it doesn’t work with stream tracer.
Someone of you have some suggestions?
Best regards,
Andrea
