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

overrideprotectedvirtual

When attached to a RelaxationGridBuffer, sets up the dispatch configuration to cover the entire grid with a single workgroup dimension along Y and Z, and a workgroup size along X that is either the default 16 or the value supplied at construction.

Parameters

buffer

The attached buffer, expected to be a RelaxationGridBuffer.

Reimplemented from MayaFlux::Buffers::BufferProcessor.
