Hello everyone,

Is there a way to segment the triple junctions from a polycrystalline rendered volume in dream3D? I would need to export the list of triple junctions and the position of the pixels if it's at all possible.

Thank you very much!

Hello Jack, 
   I don’t think we have any specific filters that would accomplish this. If you are adept with some python you could probably write up a quick algorithm that for each pixel compares all “face” neighbors feature Id with the current feature Id. If the number of differences is greater than 2 then it is a triple (or higher order) junction.

If you have a surface mesh (using QuickMesh or Surface Nets) you can filter out the Nodes based on the node id. See the documentation for those filters for more information.

I think you can use the surface mesh generation filter (that fits a triangular surface mesh to the microstructure) and export it.
