Member Function Documentation

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

Perform some initializations. Do not call this method manually.

Reimplemented from osgParticle::Operator.

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.
