Atom is a new geometry plugin for 3dsmax.
It creates similar effects as you can see in After Effect's Plexus. Atom uses Particle Flow to generate lines, points and faces between the particles.
Tutorial : https://vimeo.com/125819240
So all you do with Pflow can be used by Atom, any simulation, MassFX particles...etc
The result is refreshed when the particles are updated so that's a non destructive workflow.
You have control over the number of lines, the search distance...etc
All the parameters are animatable.
You can use a multimaterial to shade it.
That's a geometry so you can also deform it, smooth it...etc
You can bake complex Atom objects using Alembic(prefer the free Exocortex Crate plugin) or Xmesh.
Update V2.0 :
1 : You can now control the length of the lines between the particles.
2 : you can fade the faces at render time with a vertex color support
3 : you can use a mesh instead of particles as points source, so it takes vertices and vertices selection. you can animate the source mesh, deform it, change the number of vertices, slice, volume select...etc
