process_batch()

void MayaFlux::Nodes::Network::ModalNetwork::process_batch ( unsigned int  num_samples )

overridevirtual

Process the network for the given number of samples.

Parameters

num_samples

Number of samples/frames to process

Subclasses implement their specific processing logic:

1. Update internal state (physics, relationships, etc.)
2. Process individual nodes
3. Apply inter-node interactions
4. Aggregate outputs if needed

Called by NodeGraphManager during token processing.

Implements MayaFlux::Nodes::Network::NodeNetwork.
