CloudCompare forum

Hi,

Ideally, you would add Open3D as a submodule. But it's also acceptable to let developers simply install/compile it on their side and add the necessary CMake options to point to it.

Then you could compute the distance between the cloud and the polyline (With 'Tools > Distances > Cloud/Primitive dist.').

Then you can extract the points which are really close to the polyline based on this distance (with 'Edit > Scalar fields > Filter by value').

What do you mean by "ants to finalize the Selection with another point to create a 2D polygon" exactly?

Is it because the trace polyline is not closed maybe?

If there's one (or several), you would see them in the cloud properties. And if there is, then you can probably remove all the other options.

Yes, that's because with the command line you need to explicitly specify how to manage large coordinates.

You should add just after

Not sure to understand... Does your scan have an associated scan grid (because in this case you don't need to use any of the other options. If not, then you need a radius as large as possible so that enough points are captured in all areas of the cloud (normally the 'Auto' button works quite well to...

And what the bounding-box looks like once you've loaded the cloud?

There's good chances that Quick Terrain Modeler does manage properly geographic coordinate systems...

Sadly CloudCompare is not able to create (mesh) textures.

Can you send me these meshes so that I can double check things on my side? (the new version of CC is more robust, so the C2M distances should not have the same issue as before with 'flipped' distances, but I don't see why the reported distances would be much larger than what you expect...). Essentia...

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. Thank you. How can I check or edit this upon import? You'll see that right...
