setup_processors()

void MayaFlux::Buffers::RelaxationGridBuffer::setup_processors ( ProcessingToken  token )

overridevirtual

Create and attach RelaxationStepProcessor (default processor) and RelaxationEmitProcessor (flat processor), and set the per-cell vertex layout on this buffer's own storage.

Parameters

token

Processing domain (typically GRAPHICS_BACKEND).

Reimplemented from MayaFlux::Buffers::VKBuffer.
