I've been trying to analyze various surfaces of a large (3 M) boulder (1,000,037 points) for planarity, mean curvature, and roughness.
I've sampled the photogrammetry file to convert it to a point cloud and have segmented the desired surfaces for individual analysis.

I use the Tools/Other/Compute Geometric features and no matter what neighborhood radius number I use, all three calculated parameters come up with the same number as the neighborhood radius.
I've run this process dozens of times now using the default-suggested value, inputting values ranging all the way from 0.0001 to 0.5, and no matter what value I use for the neighborhood radius, the results for planarity, mean curvature, and roughness all return the same number as the neighborhood radius. What am I doing wrong??

Can you maybe send me a sample point cloud? (to 'admin@cloudcompare.org)

And also the set of parameters (radius values) you've tried?

Hi Daniel,

I've forwarded a dropbox link to the files. The file size was too large for an email.
Thank you for your help!

Dave

p.s.
I've modified the slices to be a uniform 1 m² on each face (1.8m tall x 0.833 wide)

Thanks, I've received the data and replied to your email.

And for the records, the resulting scalar fields were different, but the initial confusion came from the GUI...
