The only tool to compute volume from a point cloud is the '2.5D Volume computation' tool (https://www.cloudcompare.org/doc/wiki/i ... .5D_Volume)
But it's working under quite specific conditions, and you'll need a very dense point cloud (which doesn't seem to be the case here?)

Re: M3C2 Plugin
Not really...
You can definitely set the camera to look from the top (with orthographic projection), and you'll still see the colors and optionally the color scale to the right... but not in a fancy way like your example.

Re: resample input cloud option when using -RASTERIZE in command line mode
Oh, that was a good call: this was actually missing in the documentation, but you can use the -RESAMPLE sub-option (I've updated the wiki).

Re: Can't load OBJ
You have to enable the QCORE_IO_PLUGIN project (CMake option PLUGIN_IO_QCORE).

Re: M3C2 Plugin
So the 'Visible' option (and all color scale options as well) are in the cloud properties (on the left side, below the DB tree, once a cloud is highlighted. And you can create an absolute color scale, with labels, etc. with the 'Color scales manager' : https://www.cloudcompare.org/doc/wiki/index.php...

Re: Wear on wooden power line beam through years
The cloud looks a bit 'rough' and inaccurate from what I can see? Have you tried to segment it with the 'scissors' tool maybe ( https://www.cloudcompare.org/doc/wiki/index.php/Interactive_Segmentation_Tool ) or the Cross Section tool? ( https://www.cloudcompare.org/doc/wiki/index.php/Cross_Section )...

Re: Volume density measurement
Yes, that's it. And for the 'volume density' we simply divide the number of points by the volume of the sphere (while for the 'surface' density, we divide it by the surface of the equivalent circle).

Re: displaying a single color on the scaler field
It is not clear to me what the problem is exactly, but I would guess that there's one point that has a totally different distance from the rest. This make me thing about a 'limitation' of the C2M that was fixed recently in version 2.13.1 version. Can you test with this new version and report here if...

Re: Calcul de volume de tranchée à partir de Cloud Compare
Voici ce dont on a discuté par email (pour continuer le fil ici): Quelques commentaires : - si c'est plus simple, ou si le trou n'est pas rectangulaire, vous pouvez aussi utiliser l'outil 'ciseaux' (Edit > Segment) qui permet de découper selon un contour - utiliser un mesh (OBJ) aurait l'avantage d'...

Re: select point cluster by scalar field
So the Connected Components tool uses a simple 'connected components labeling algorithm' applied to a regular grid. And we simply use the cells of the cloud octree considered as a given level of subdivision to convert the cloud to a grid. The octree is a recursive subdivision of the cloud in 8 cubes...
