I am not sure if there is a way to do this, but I thought I’d ask.
I have a streamline with custom source filter that is working wonderfully, and because of my dense meshing on the custom source produces a wonderfully dense set of streamlines.
What I would like to do is basically a delauney 3d, but instead of being a convex hull, “shrinkwrap” the streamlines, so that I can have a volume that the streamlines occupy to clip the field.
My current workflow involves exporting the streamlines as .stls and “shrinkwrapping” them in CAD, but I’d really like to implement this in Paraview.
One idea that I had was to somehow decompose the streamlines into just a point cloud to be surfaced. As I understand it (How to create the surface of a point cloud object?), however, ParaView can only surface convex hulls, and although VTK has some more advanced surfacing, that is not currently implemented in ParaView.
I think I could do the surface reconstruction elsewhere (besides my CAD approach) such as in Meshlab, but I’m actually not sure how to get the point cloud into meshlab.
