CloudCompare forum

I am wanting to create a new point cloud with just NaN points from my existing point cloud. Is this possible?

Thanks.

When you say 'NaN' points, you mean points with a NaN scalar value associated to them? Or NaN coordinates?

Anyway, if it's the first option, you could export the points with valid values (just use a large range in the 'Edit > SF > Filter by value' method), then compute the distances between the original cloud (compared) and the subset (reference) and keep the points with distances > 0.
