set_gpu_executor()

void MayaFlux::Nodes::Network::InstanceFieldOperator::set_gpu_executor	(	std::shared_ptr< Yantra::ShaderExecutionContext<> >	executor,
		bool	continuous = true
	)

Attach a GPU executor and switch to async dispatch mode.

Constructs a GpuComputeNode from the executor. On each process() call the node's compute_frame() is driven instead of the CPU field loop. The on_complete callback reads gpu_result.primary as tightly-packed mat4 rows (16 floats per slot, in slot-index order) and writes into m_slots directly.

CPU field bindings are preserved but ignored while a GPU executor is attached. Passing nullptr clears the GPU path and restores CPU evaluation.

Parameters

executor	Pre-configured ShaderExecutionContext. Output binding must be sized for slot_count * 16 * sizeof(float). nullptr clears.
continuous	If true the node re-arms after every completed dispatch.
