void MayaFlux::Buffers::RelaxationEmitProcessor::on_attach ( const std::shared_ptr< Buffer > &  buffer )

overrideprotectedvirtual

Cover the grid with a 1D dispatch and write EmitParams.

Parameters

buffer

The attached buffer, expected to be a RelaxationGridBuffer.

The local size is fixed at 256 and the group count is ceil(cell_count / 256).

Reimplemented from MayaFlux::Buffers::BufferProcessor.
