- TL;DR Summary
- I have a point cloud representing broken bonds and I would like to represent the density of the cloud at some location in space.

Hi. For some background, I am running molecular dynamics simulations of silica fracture in LAMMPS. Each point represents the location of a broken bond. I would like to find regions where many bonds are breaking, which I speculate would be locations of crack formation. These computations are being done on MATLAB using data from the LAMMPS simulation.

I could come up with a way to compute the density. For example, I could sum the inverse of the distance from a specified location and each point. The sum would represent the density at that specified location. However, I was wondering if there was some standard and simple way of computing density of a point cloud, or one which would be particularly relevant considering the application. Thank you!
