Hello, I have some questions. First, can I choose the quantity of points to show in the display?
Second, how I can compare a cloud with a mathematical structure?
thank you for the answers!!!!

You can only set the number of points above which the LOD mechanism will be activated (to display the points progressively and not all at once). This can be setup via the 'Display options' dialog.
And to compare a cloud with a mechanical structure, you'll have to either create a (triangular mesh) surface of your function... or develop your own code (as a plugin for instance).
In both cases it might not be straightforward :D.

Hello,
I should do a check on the completeness of the data of my cloud. I have to break the cloud in a regular grid (eg. from 20cm) and I want to know how many points there are inside. Is It possible?
thank you

You could use the 'Rasterize' tool (with a step of e.g. 20 cm) and then export the resulting grid as a cloud with the 'cell population' as scalar field.

Then you'll be able to extract the points (cells) with a population below a given threshold, or check the global histogram, etc.
