i took the fountain example from google code and changed the renderer from Pixelrenderer to PV3DParticleRenderer. I also have put a StatsView to see how it is going. FIrst everything seems to be normal, it makes 25 Fps or so. But memory usage gets constantly higher (it does drop sometimes a little but not back normal again) and after a while (some minutes) the Fps also drops down to 10 and even lower. It starts with using 7 MB and after a minutes its 30 MB and growing..

Any ideas?

Here is the code i am using:



package

public function flintfountain()
{

addChild( viewport );
pv3dRenderer = new BasicRenderEngine();
scene = new Scene3D();
camera = new Camera3D();
camera.z = -300;

addChild(new StatsView(pv3dRenderer));
particles = new Particles();
scene.addChild(particles);
emitter = new Fountain();
emitter.position.y = -100;
flintRenderer = new PV3DParticleRenderer(particles );
flintRenderer.addEmitter( emitter );
emitter.start();
addEventListener( Event.ENTER_FRAME, render, false, 0, true );
}

private function render( ev:Event ):void
{
// render the view
pv3dRenderer.renderScene( scene, camera, viewport);
}
}
}

I ran your code with no problem. Then, just to check, I dropped back to an earlier version of Papervision and ran it and had the problem you observe. When using the original papervision 2.0 beta the ...
