Dividing a 3D model into sections based on proximity to specified points

[jmrs14]

Hi,

I'm a complete novice when it comes to CC, and I was wondering if anyone knew/if it's possible to get CC to divide a 3D model into sections based on proximity to set points? For example, if I had a model of a building and I wanted to divide it into areas based on which set point that part of the building is closest to.

I've tried looking for the answer online but no luck so far.

Any help would be greatly appreciated.

Cheers!

Ah, you can maybe use the 'Tools > Distances > Closest Point Set' tool?

If you have a cloud with one or several 'set points', and another cloud representing your building (you can sample points on your building model if it's a mesh), then you'll get for each building point it's closest 'set point'. It's not easy to visualize the result, but at least you can export both clouds as ASCII/CSV files and do something externally...

Of course, if you are able to do something in Python for instance (with CloudCompy) you could generate a color or a different scalar value for each set point.
