A quick mail just to give more opinions on the subject.
We stopped using osgParticle for performance reasons. osgParticle is a little
bit overengineered for a real time particle system, the particle simulation
loop is quite bloated with different layer of abstractions that are finally not
so useful. Moreover, the particle class is quite big, with lot of informations
that are not useful for all particle systems. It is really not suited for high
performance particle systems (thousands of particles).
Finally, doing the particle simulation on my own was easier, and give me more
control. For exemple, the particle system must work with earth-like databases.
I have several effects (explosion, reactor trail, dust trail), they just share
the drawing code (convert particles to osg::Geometry) and some basic particles
management, and it is sufficient...

OK, I agree with you, the main problems with the current library are precisions
issues and performance, I hope you'll be able to handle them !

Hi Serge,
I plan to keep full back-compatibility of previous osgParticle
library. Its design and structure is still usable and easy-to-extend
in my opinion.
