Sorry for the late reply. I agree, a proper way to generate random clouds of any type would be nice (related: issue #5097). I think we should add a few...

Great that you investigate the NormalDistributionsTransform so thoroughly and report things to fix and improve! I looked into this a bit: Magnusson's thesis says: "The constants c1 and c2 can...

@grischi Thank you, that makes a lot of sense. Applying that logic to the computation of the c1 parameter, would the integral of the (unscaled) 3D normal distribution then be...
