Calculate Gradient returning NaN

Post by TechTeam »

Hi there, relatively new to cloud compare, so this might be a really easy fix.
I am trying to compute gradient on a C2M singed distance scaler field for a point cloud with 1,107,667 points. Each time I run it returns a grey point cloud consisting of either NaN or a single value with the majority of points as NaN.
I have no idea why its doing this, and have been able to run the gradient scaler field on other point clouds.

Can you maybe share the point cloud with me? (admin [at] cloudcompare.org)

For the records: this was a glitch due to very small coordinates (~10e-5). I fixed this in the next 2.12.alpha release.
