I have a (time-dependent) system of ~100k moving points in a confined space. Each point has its own Cartesian coordinates and weight (w) in the form of (x,y,z;w).

I'm looking for a software/app/package to create a snapshot of the 3D spatial density map of these points. (something like this). Like you see in this figure, the points are not going to be displayed individually, but only a transparent cloud will be drawn whose local intensity is proportional with the local number of points.

The final goal is to create a movie of the changing 3D spatial density with time.
So far, I have tried R, Matlab, Origin. But no success!

Thank you for your help!
