CloudCompare forum

Thanks for your time and thoughts Daniel,
I appreciate it greatly!
I'll try for no more novels to you for at least a while ;P

Hi Daniel,

I am comparing C2M with M3C2.
I have read on both, and there are papers out there comparing them, which is great.
I think I understand their strengths and weaknesses.

Now, I ran C2M twice. Once using Delauney meshing, and one with Poisson meshing.
I understand Poisson is meant for ...

Thanks Daniel!!

Hi Daniel,

I have two questions about the calculation of the default input parameters.

1. For the core points, the value doesn't have a unit. What is the unit? The same as my data, meters? Is it a search radius? One core point in each 0.254m radius? Or is it a proportion? For example, 0.254. Can ...

Hi Daniel,

I've been doing C2M, making a mesh of a high quality SfM derived dataset.
All of the results (several clouds compared to this mesh) have what appear to be errors of geometric shapes.

I used the same reference data to run DoD and M3C2, and the artifacts are not occuring in the results ...

Hi Daniel,

Yes, you're right.
I'm talking about the "active" dropdown list.
In CC, there are 5 scalar fields. (6 if you include "none").
When I export as rasters, I choose the option to export all scalars.
When opened in Arc, these rasters have 6 bands.

Example of range in data:

Hi Daniel,

I have performed M3C2 on several clouds against my reference.
The resulting data contains 6 bands.
In CC they are listed as
1. none
2. SD of compared cloud
3. SD of reference cloud
4. Change significance
5. Distance uncertainty
6. M3C2 distance

I recorded the range of values in each ...

Hi Daniel,

I understand how c2c, c2m, and m3c2 work, I think.
I know there are pros and cons of each method, especially as they relate to the quality of the data sets being compared.
For me, I have a very nice, high quality, UAV SfM derived cloud of my target as a reference.
Then I have very ...

I'm not sure I follow. I'm using the newest version.
Thanks,

Hi Daniel,

I'm outputing my scalar results as rasters (this will let me investigate their stats), and I believe I have chosen to interpolate in the export window, but the results are not interpolated.
Is it not the "interpolate SF" toggle?

Thanks,
Lindsay
