Hi there..

I´m working on a 3D Plumbing Minigame..
Perhaps you know such a thing from Bioshock (hacking):

My onw uses 3D models as Pipes...

I´ve the Pipeline System.. the times.. everything is great..
BUT...

I´ve no clue how to create the water (or what else) floating through my 3D Pipes...


I thought of many Sprite-Entities wich are bouncing in the pipes...
Or a great number of particles with collision...

But.. that are all performance killers...

So.. do you have any good idea??
