PUDotNet        

PUDotNet is a simple C++/CLI wrapper class to use Particle Universe in Mogre.

help For questions is this forum topic.

Look to the Particle page for basic particle information and further links.

Updated in March 2011 by user tafkag for Mogre 1.7 with Particle Universe 1.5.

The source codes for PU 1.2 and 1.4/1.5 are attached to this wiki page. (see bottom)


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.

How to use


First you need to buy Particle Universe (for about 10 Euro/Dollars) and compile the wrapper code.
For compilation of the wrapper it's needed to link against the Mogre version of the Ogre libraries when building PU, otherwise it will not work. (means: The Ogre sources, which are modified specific for Mogre)

Additionally you need to add PUDotNet to the file plugins.cfg:

  • release version:
Copy to clipboard
Plugin=ParticleUniverse
  • debug version:
Copy to clipboard
Plugin=ParticleUniverse_d
