Jeff Wagner talks about pgfind in his VEX masterclass and touches on point clouds a little bit, but sometimes it's hard to creatively imagine novel uses for these.

Hi Jon -

This may or may not be helpful but in the vellum solver (for the grains) there's a VOP called “get_neighbors” that uses both pcfind and pcfind_radius (switched by the “uniform_radius” parameter), and there's a bit commented out on pgfind (which IIRC is for accessing points that are spatially partitioned in to blocks the way a VDB might, could be wrong tho) - all of that could be a bit of a clue as to what the finer distinctions between them are.

Oh nice, very clever use of Voronoi fracture!

Unfortunately we don't have none of that in SI.

Anyway, plenty to like in Houdini, so no complaints here.

cheers,

When I get further along with it I'll try and post the results after I've had a proper go at it - the ICE tree is a bunch of nested operations in a single graph (mostly on account of the sorting), whereas in Houdini I think it'd be better expressed as a series of SOP nodes in a foreach or something.
