Re: Compare Point Clouds

Well, it all depends on your 'reference' cloud density. If the point cloud that isn't measured with a tachymeter is quite dense, then it can be ok to use C2C.

Re: Create Mesh

You have to compute the normals first: see https://www.cloudcompare.org/doc/wiki/i ... %5CCompute

Mind that the normals orientation is very important for the Poisson Reconstruction algorithm.

Re: Cloud and plane intersections

Sorry, but I don't really understand how it can be simpler to generate a STL file from a laser scanner cloud :D (that's generally the opposite). Maybe you want to discuss that directly (in French) by sending an email to admin@cloudcompare.org. And if you can share data that may be useful also.

Re: Point Cloud to Mesh with .e57 file?? Please Help

Maybe you can first start by sharing a snapshot of your point cloud? ;)

Or you can directly send me the cloud to admin@cloudcompare.org. So that we can tell you what's possible to do.

Re: tank analysis with ransac problem

This really looks like the Noise filter algorithm (the only difference being that the SOR algorithm will go through all points, one by one, instead of being random).

Re: Color From Scalar Field

So you should definitely set the Alpha component (= transparency) to a fix value (255). For the others, it all depend on what you were trying to achieve. Another option (maybe simpler) is to defined your own color scale with 'Edit > Scalar field > Color Scale Manager' (to define your own custom colo...

Re: .zlas files

Ah, that's a closed source format (and a shame, as laz was already existing and open ;). We don't (and cannot) support it.

Re: Extract Connected Components in command line

Ok, I modified the -EXTRACT_CC option code to append the cloud name and its index in the file (in case multiple clouds have the same name ;). It will be available in the 2.13.1 version that should be released soon. Meanwhile, I believe you can simply use the 'ALL_AT_ONCE' option to save all componen...

Re: Remove vegetation in agricultural field

To remove vegetation, have you tried the CSF plugin? ( https://www.cloudcompare.org/doc/wiki/index.php/CSF_(plugin) ) You can use this 2.13.1 preview version, where it has been improved: https://www.cloudcompare.org/release/CloudCompare_v2.13.1.preview_setup_x64.exe (the 2.13.1 version should be rel...
