Move scalarfield index, or use "last" in set_active_sf in command line

Hi, I am loading a large number of .laz files (up to ~600) in command line mode, to first perform a filter (to extract terrain from sf="Classification", value "2"), then subsample this, and then merge all of them. It turns out that some of the scans from along the border have 2 f...

"Blanket effect" - remove/filter points on ground

Hello, I'm happy to have found this software, it looks very promising. I'm doing a wind analysis and have lots of laser measurements available, so I'm aiming to export in the end as .stl. What I need is a surface with mostly the terrain and slope, but houses and vegetation could as well show up as &...
