Thanks a lot, everyone! Polygonizer would generate an isofield, and it would get rid of the original point positions, unless I misunderstood how it works.
It seems like shrink wrap does the trick, luckily the cloud can be approximated with a geometry here. I've looked into houdini quickly as well, before I wrote here, what I found was that the triangulate2D node is meshing it perfectly, but concave stuff was a problem of curse.. I thought someone here, at work ( I'm a houdini noob atm ) could split up the cloud for me based on angle of normals, mesh the pieces and merge the geo, or something, but I've read the suggestion about wrapping, and it did the trick. I've looked at pcISO as well, but it was beyond my current knowledge, to make it work. Anyway, thanks a LOT again, everyone!
