dispatch_core()

GpuChannelResult MayaFlux::Yantra::GpuDispatchCore::dispatch_core ( const std::vector< std::vector< double > > &  channels, const DataStructureInfo &  structure_info  )

protected

Full single-pass dispatch.

Drives prepare_gpu_inputs, on_before_gpu_dispatch, bind_descriptor, and GpuResourceManager::dispatch.

Parameters

channels	Extracted double channels from the input Datum.
structure_info	Dimension/modality metadata from OperationHelper.

Returns

GpuChannelResult containing primary float readback and aux buffers.
