Re: [osg-users] Density of the SmokeTrailEffect

2011-08-31 Thread Brad Colbert 
No luck so I tried:

osgParticle::ModularEmitter* emitter =
dynamic_cast( 
smoke->getEmitter() );

if ( emitter )
{
osgParticle::ConstantRateCounter* counter =

dynamic_cast( emitter->getCounter() );

if ( counter )
counter->setNumberOfParticlesPerSecondToCreate( 
500 );
}

and still no luck.

Hi folks,



I have a simple rocket model with a SmokeTrailEffect added and the trail is 
more like a train of "puffs".  How do I control the "density" or closeness of 
the puffs to make it look more like a trail?

The SmokeTrailEffect's ModularEmitter object has a parameter that you can tweak 
to compensate emission rate for movement rate.  I've not used it myself, so I 
don't have any advice on how exactly to adjust it.
