Member Function Documentation

void osgParticle::AccelOperator::beginOperate (  Program *  prg  )  [inline, virtual]

Perform some initializations. Do not call this method manually. Reimplemented from osgParticle::Operator.

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.
