CloudCompare forum

Frankly I don't know... nothing really makes sense. I guess you are using the latest driver?

Which version of Windows are you using?

Can you open a ticket on github and tag Thomas Montaigu (the new LAS I/O author) maybe?

Well, it's hard to see (don't hesitate to activate the EDL shader ;), but assuming you have some overlapping surfaces, you can indeed use the Edit > Translate/Rotate tool to roughly align the scans, and then use the ICP tool (see https://www.cloudcompare.org/doc/wiki/index.php/Alignment_and_Registra...

I think the command line mode should help you do that? (with the -SS option):

1) Sadly, I don't thing the current python scripting tools will let you change the behavior of an algorithm (but they might allow you to do this clustering approach you are referring to). The best way would be indeed to modify the C++ algorithm directly 2) You can now filter points based on their RG...

So, maybe the authors of the plugin could be interested (not sure about that), or maybe more the 3DForEcoTech - https://3dforecotech.eu/ - and more generally the LIDAR/forestry communities?

- smoothLaplacian: je ne pense pas (si on parle bien de l'option de lissage d'un maillage)
- Resample Input Cloud: oui ça a été rajouté dans la version 2.13 (voir l'option -RESAMPLE de -RASTERIZE - https://www.cloudcompare.org/doc/wiki/i ... _line_mode)

Also, a classical issue is if the points are expressed in a 'geographical' coordinate system with X and Y being angles, and Z being in meters (i.e. with a totally different scale). CC expects all 3 dimensions to be the same.

If you use quite recent versions of CloudCompare, you have an option to show the points as circle in the 'Display > Display settings' dialog.
