Intersection / Hit / In-Out-Volume Test between Objects and Particle Shapes

[TubeSmokeGuy]

In many ways.  
Object test, surface test,, collision operators... to name a few... they all can lead to the next event where intersecting particles can be sent.
Start with Collision operator, and just change from bounce, to continue...

Hey thanks for your reply!

But do the operators you listed test the particles shape mesh (its ture visible geometry) or just the particle (the point in the center of the shape)?

I think they do the second and that's not what I am looking for.  Or do I missunderstand something?
