Hello, it seems when merging giant point clouds sometimes in the resulting PC there are massive amounts of points missing.
This might be related to a limitation of the pointcloud object, however in this case I think a warning would be adequate…
I did a quick video:
Hi Andreas,
This could be a display issue as well. Can you look at the Object details of each cloud before adding, as well as the result?
It’s potentially a bug, i’ll ask around a bit and get back to you.
On a side note there is the potential here to reduce the number of points, either by using cloud compare or the cockroach plugin on food4rhino on the foliage.
yes, I am running some test with cockroach, this is probably a great program but I am missing a manual which explains the algorithms a little more specific.
Is there a simple to use approach you know of to have an “intelligent” downsampling so that areas of high density will be reduced more than low dense areas?
Would cloud compare be the better bet here?
I haven’t been able to replicate the disappearing points when adding points to a point cloud.
Can you post your SystemInfo (Rhino Command Line)

Your video card looks pretty solid and up to date. One thing we can try is to disable any superfluous plugins that don’t ship with Rhino via File>Preferences>Plugins

I don’t a good answer to your previous question offhand, i will have to do some research.
