initialize()

void MayaFlux::Nodes::Network::ParticleNetwork::initialize ( )

overridevirtual

Called once before first process_batch()

Use for expensive one-time initialization:

• Building neighbor maps
• Allocating buffers
• Computing lookup tables

Reimplemented from MayaFlux::Nodes::Network::NodeNetwork.
