osgParticle::AccelOperator::META_Object	(	osgParticle	,
		AccelOperator
	)

const osg::Vec3 & osgParticle::AccelOperator::getAcceleration

(

)

const [inline]

Get the acceleration vector.

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.

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.

void osgParticle::AccelOperator::beginOperate

(

Program *

prg

)

[inline, virtual]

Perform some initializations. Do not call this method manually.

Reimplemented from osgParticle::Operator.
