title: Slicing 3D point cloud into regular triangles/squares in Python
body: <p>I am working for my thesis on a 3d point cloud containing x,y,z,R,G,B and other parameters. For a matter of calculations I would like to divide the cloud into regular fractions, let's say squares or triangles of side 1 meter, and then perform in-depth analysis on each of them. Is there an algorithm or a package in python that allows to do this, maybe exploiting the geometric distance between the points?</p>
