History: PUDotNet
Preview of version: 4
PUDotNet is a simple class to use Particle Universe in Mogre.
For questions is this forum topic.
Look to the Particle page for basic particle information and further links.

Published in February 2011.
It was created for Mogre 1.7 and PU ?version?. (For further versions, maybe it needs some modifications.)
Note by the contributor:
This code is a quick-and-dirty solution:
Grab the code and have some fun. It's very simplistic, not a real wrapper of the API, more a kind of binding to the plug-in. I will not have time to support this in any way, but I think I should at least share it with you in case somebody find it useful.
TODO:
Write how to use/embedd it. (It seems so that you need to compile C++ code ... for use with C#.)
