Hello, we are using the compass tool for projects and have encountered occasional issues with unexpected crashes. The workflow is seemingly simple. Load a few clouds (typically 2-3 clouds, 100M points each). Then open compass tool. Use the plane fitting tool to create planes. Also use the trace tool...

Another suggestion which might help is, whenever I use Poisson Reconstruction I always turn on the option to output density, then I filter the resulting mesh to remove regions with low point density. Even if the normals are good it often extrapolates surfaces where I don't want them.

Hi, regarding the double click re-center feature, I think I've experienced this issue or something similar in several recent versions. Sometimes the double click will register, but the center of rotation is not where I double clicked, it's up and to the left. I found a work-around that worked for me...

Hi, I'm trying the "draw normals as lines" function for the first time and have been getting an error which causes a crash. With v2.13.0 (Feb14), I compute normals on a small cloud, then click the "draw" check box. The error that pops up is "ERROR: 3:7: 'varying' : cannot be...

Hi, I wrote a short script using the python GUI plugin recently which does something similar, basically it was meant to delete entities which weren't visible. I think the number of points is an attribute you can access through the python API, or definitely you can after passing the points to a numpy...

Hi Madeleine,
You can compute features for individual red green or blue components, not all three at once :)
Try R_SC0_PC1, G_SC0_PC1, etc. (single letter R,G or B for each feature line) Please let me know if this helps or if I'm misunderstanding your question.

Hi Daniel,
Looks like I should have tried that too, because it works in the latest 2.13.alpha version. My bad!
I had been holding off on upgrading but now might be a good time I guess... :)

Hello! I've noticed in perhaps the last couple of versions that I have a very difficult or impossible time using the "single click object picking" functionality. I often output hundreds of point clusters from Python and want to interactively select them. But 99% of the time, clicking anywh...

Hi Daniel and Dimitri, Wow, I should have posted here sooner! That's big news. And makes sense of why geometric features suddenly became available in CloudCompare :) Actually I was in grad school around the same time, 2018 to 2021, and since I wasn't aware of any classification tools other than CANU...

Hi, I think it is time for CANUPO to get an upgrade to reflect the last 10 years of development in point cloud semantic segmentation. While very powerful for some things, CANUPO: - is limited to binary classification (or rather, multi class classification is cumbersome) - uses only geometric feature...
