## 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.
