So pay attention when computing the distance in CC with the C2C distances computation tool, that the clouds density and non-overlapping parts (or holes) will have a big impact. It's better to use M3C2 for instance. And for registration, it's a similar problem. Make sure the 'overlap' parameter is no...

Generally it's because the GPU (or its driver) is blacklisted by Qt. Two options: - either you also have in parallel an Intel chipset. In which case it may be picked by default and rejected by Qt. In this case you should be able to force Windows to use the NVidia card when launching CC (via the NVid...

Ah, that would be the graphic card memory (GPU).

Sadly, you won't be able to achieve that apart from changing the code of CloudCompare...

Which version of CC are you using? Because normally v2.14 should automatically export normals in a LAS file as an Extra field (EB-VLR). Also, make sure the 'normal' fields (NormalX, NormalY and NormalZ) are loaded as such in the GUI ('Load As Normals' section). Normals are not very standard in LAS f...

How were the colors generated (or was the mesh textured when imported in CC)? And which format are you using to export the mesh? Because some formats don't support textures, or they don't support per-vertex RGB (which is what CC is able to generate itself). And then some software tools don't manage ...

Thanks, I've linked your message on the git issue discussion: https://github.com/CloudCompare/CloudCo ... ssues/2152

So the -O option has to appear first, because you want to load the cloud before doing anything ;) CloudCompare.exe -O ".xyz file" -COMPUTE_NORMALS -SAVE_CLOUDS FILE ".las file" And you can also use '-C_EXPORT_FMT LAS' before calling anything so as to have the auto save feature au...

The use ICP, with the right overlap parameter. See https://www.cloudcompare.org/doc/wiki/i ... n_with_ICP and https://www.cloudcompare.org/doc/wiki/index.php/ICP

Because no one took the time to implement it :-D

That's an open source project after all ;)
