seed_from_upstream()

virtual void MayaFlux::Nodes::Network::GraphicsOperator::seed_from_upstream ( const GraphicsOperator *  upstream )

inlinevirtual

Receive upstream vertex state before process() is called.

Called by OperatorChain::process() only when consumes_upstream() is true. Implementations seed their internal vertex buffer from the upstream operator's current output. Default no-op.

Parameters

upstream

Last GraphicsOperator that ran before this one in the chain, or the primary operator if this is the first chain entry. Null if no upstream GraphicsOperator exists.

Reimplemented in MayaFlux::Nodes::Network::FieldOperator, and MayaFlux::Nodes::Network::PhysicsOperator.
