Best approach to downsample composite dataset?

Hi, we have a composite dataset (.vtu) files and would like to downsample the data. Our solution was to merge blocks and apply a glyph filter with uniform spatial distribution since Extract Subset doesn’t work on a composite dataset. The glyph idea works but I was wondering if there were any other clever solutions that people could suggest. I would especially be interested in a solution that allows non-uniform sampling so as to sample the data in interesting regions more finely than in uninteresting regions. Thanks, Terry

Hi Terry,
I don’t think this can be done in any cleaner of a way than you used. Although not exposed, the LOD filter just deletes points in a really rough way, that you don’t want to use. Ala
