No, What I meant is that PCV, aside from allowing to get difuse lighting look, allows to understand the topology of a point cloud. BUT, for high density scans that are chopped in tiles of about 500x500m, PCV fails to capture enough detail. In order to capture similar details you would need to furthe...

tx Daniel!! such a tricky one.

I'll update to the new beta and be aware to see if it ever triggers again

just to double check, I did interpolate the original Intensity into the broken one, it looks seamless. PCV also got damaged, https://i.postimg.cc/G89Y81S8/Image-43.jpg https://i.postimg.cc/2bJWnXPH/Image-44.jpg PCV was computed prior to separating the ground so they should blend seamlessly so, as of...

I tried to reproduce using the same cloud but It is not as simple as segment out, and merging.... sadly.....

also notice how the intensity values in the graph go down to -5k now

AFTER MERGE

I think I noticed what could be going on on the damaged SC. This is in the latest version, the point cloud Indx ID, may have been a different but. I was already having this impression, but I saw it happen right in front of my eyes this time. I'm accuratelly segmenting ground/ off ground. So, there w...

Hi, PCV greatly enhances the perception of the topology, yet it's quality in detail capture degrades bastly with big datasets or big tiles. Even if cranking upd the rays, at some tile sizes it takes forever and the outcome is not as good as when breaking into small tiles. Which could be a solution i...

Hello Daniel,

I tested with alpha 2024/08/12 version but the issue persists!

I sen´t you email to
admin@cloudcompare.org

With small sample dataset, when you merge the two clouds, you'll see that no index for each cloud is generated.

Cheers!

In the latest version of yes, the one that was pushed so the corrupt.bin was possible to read. I found a bug, that could be related to the issue. When you merge 2 clouds and you tell to YES generate an scalar field so you can ID each. It is not working, it only gets one color. Not sure if it matters...

I've not yet detected the moment this happens, but the scalar fields are getting damaged. I believe it occurs when merging clouds. As scalar fields get values lost in scattered parts of clouds. and I'm segmenting clouds and merging all the time atm. I also noticed and old bug thaht is thath scalar f...
