Re: Calculation of verticality
I found a bit more info in the paper "STREAMED VERTICAL RECTANGLE DETECTION IN TERRESTRIAL LASER SCANS FOR FACADE DATABASE PRODUCTION": Captura.PNG But I still don't understand exactly how to create the tensor, can anyone tell me how to create it from the coordinates of the points that mak...

Calculation of verticality
Hi! I am using CloudCompare's "Compute geometric features" tool, and a question has arisen. According to the documentation (paper "Contour detection in unstructured 3D point clouds") the variable "Verticality" is defined as: 1 − |<[0 0 1], e3>| I'm a bit lost and I don'...

Re: Numerical scale
Hi Daniel! Thanks for the fast reply. Could be possible to explain how it works the "Adjust zoom" tool? I mean, could be possible to explain me how is possible to set up a scale of 1/10 (1 cm in the screen is equivalent to 1 cm in the reality)? Sorry if the question is too obvius.

Numerical scale
Hi All! Could you let me know if there is a way to know the numerical scale of a view?
Perhaps it would be positive to give the user the option to select a numerical scale in the view (1/50, 1/10,000...) as GIS do, and not just visualise a graphical scale.
Thanks!

Re: Obtaining the eigenvalues of the point cloud
Hi Daniel! Yes, I applied the global shift in CC. I tried again the same code but using the shifted coordinates and the result is the same. Could be possible to obtain an intermediate result from CC as the covariance matrix?

Re: pan while segmenting and multi segment polygons
You only have to click in the pause button to pan while segmenting.

Obtaining the eigenvalues of the point cloud
Hi! I'm trying to calculate some of the variables of the "Compute geometric features" tool using python, but I'm getting slightly different values for the eigenvalues compared with CC with a distance neighbourhood of 10cm. I attached the very simple point cloud I'm testing. This is being m...

Re: How to save the cloud with Global Shift (Scale).
Indeed, BIN files are storing the current 'project' (or at least the highlighted elements) and everything should stay consistent in CloudCompare when you reload them. When exporting to E57, the Global Shift and Scale will be simply 'reverted' and things may not stay consistent. Well, in the general...

Re: Is the geometrical feature calculation available from the command line?
I write in this topic because I'm interested too in the availability of this tool from the command line.
