实时飞行粒子尾迹（十二）

BuildTail(osg::Vec3(0, -10, 0), mtfly);
BuildTail(osg::Vec3(0, 10, 0), mtfly);

void COSGObject::BuildTail(osg::Vec3 position, osg::MatrixTransform* scaler)
{
    osg::ref_ptr<osgParticle::FireEffect> fire = new osgParticle::FireEffect(position, 10);
    fire->setUseLocalParticleSystem(false);
    fire->getEmitter()->setEndless(true);
    fire->getEmitter()->setLifeTime(1);

    fire->getParticleSystem()->getDefaultParticleTemplate().setLifeTime(fire->getParticleSystem()->getDefaultParticleTemplate().getLifeTime()*10);
    scaler->addChild(fire);


    osg::ref_ptr<osg::Geode> geode = new osg::Geode;
    geode->addDrawable(fire->getParticleSystem());
    mRoot->addChild(geode);
}

运行效果如下：
