Hi,

Does anyone know some good papers or books (preferably german ones or at least ones that are available in europe) about advanced physics for particle systems? I recently felt like redesigning my particle system as it worked fine but was too unflexible and hard to configure. I didnt find anything useful on the web, most tutorials just cover the basics, and thats what I already have. I want to be able create really cool effects of all kind with my particle systen but got stuck on the physics. I remembered a
Commercial MMORPG-suite which had a cool particle system: using around 8 parameters, you could pretty much create any particle effect from fire,blood, water, whatever you want. Id be really glad if somebody could point me out some information! Thanks in advance!

Edit: just in case I didnt state clearly, im mostly interested in the physics calculation
for beeing able to move particles with given weigth, etc properly, not such stuff as particle collisions!

It seems like what you are looking for is a tutorial on Smoothed Particle Hydrodynamics (SPH). I suppose a reasonably good introduction is Brandon Pelfreys tutorial on the topic.

Thanks,

I had a quick look at the links and they look just like what I needed! However, my question is: can I only use this on liquids, or can I create other particles like snow, gases, etc.. too?

I'm definitely no expert on that subject, but it seems like SPH has been used to create pretty much anything that is not solid.
