void osgParticle::AccelOperator::beginOperate ( Program prg) [inline, virtual]
const osg::Vec3 & osgParticle::AccelOperator::getAcceleration ( ) const [inline]

Get the acceleration vector.

osgParticle::AccelOperator::META_Object ( osgParticle  ,
AccelOperator   
)
void osgParticle::AccelOperator::operate ( Particle P,
double  dt 
) [inline, virtual]

Apply the acceleration to a particle. Do not call this method manually.

Implements osgParticle::Operator.

AccelOperator& osgParticle::AccelOperator::operator= ( const AccelOperator ) [inline, protected]
void osgParticle::AccelOperator::setAcceleration ( const osg::Vec3 v) [inline]

Set the acceleration vector.

void osgParticle::AccelOperator::setToGravity ( float  scale = 1) [inline]

Quickly set the acceleration vector to the gravity on earth (0, 0, -9.81).

The acceleration will be multiplied by the scale parameter.
