Returns
the particle position in physical space

Returns
the particle velocity in physical space.

Returns
the age of the particle given in seconds.

Returns
the value of the requested scalar property or the passed default value if there is no such property attached to the particle.

Parameters
const double& _default:
the default value that is returned if no such property is available.

const ParticleProperty & prop:
the property type to retrieve. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to retrieve a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.

Returns
the value of the requested vector property or the passed default value if there is no such property attached to the particle.

Parameters
const vector3d& _default:
the default value that is returned if no such property is available.

const ParticleProperty & prop:
the property type to retrieve. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to retrieve a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.

Returns
the value of the requested boolean property or the passed default value if there is no such property attached to the particle.

Parameters
const bool& _default:
the default value that is returned if no such property is available.

const ParticleProperty & prop:
the property type to retrieve. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to retrieve a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.

Overwrites the particle position.

Parameters
const vector3d& pos:
The new particle position given in physical space.

Overwrites the particle velocity..

Parameters
const vector3d& pos:
The new particle velocity given in physical space.

Overwrites the particle age. This is the same as using SetProperty_Scalar with PROPERTY_TYPE_AGE passed as ParticleProperty.

Parameters
const int age:
The new particle age given in frames.

Overwrites the requested scalar property.

Returns
true if successful.

Parameters
const double val:
the new scalar property value.

const ParticleProperty & prop:
the property type to set. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to change a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.

Overwrites the requested vector property.

Returns
true if successful.

Parameters
const vector3d& val:
the new vector property value.

const ParticleProperty & prop:
the property type to set. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to change a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.

Overwrites the requested boolean property.

Returns
true if successful.

Parameters
const bool val:
the new boolean property value.

const ParticleProperty & prop:
the property type to set. See ParticleProperty for a list of properties.

const BaseObject* node_interface:
optionally a property node interface. This is really only necessary if you want to change a custom property because there can be multiple custom properties of the same type. The node interface is the explicit identifier for such a custom property.
