[Papervision3D] lens flares and particle primitives

I've given the sun a flare that disappears when the planet is in front 
of it. Calculation isn't entirely correct but ok for now. Which brings 
me to the following. Now the flare is just a sprite on top of the 3D 
scene. What is should be is a particle. Anybody tried to create a 
particle primitive yet? Otherwise I'll snoop around inside the pv3d 
classes to see if I can make one. Any of you insiders got some pointers 
where I should start or look?
