HashDensityColorProcessor()

MayaFlux::Buffers::HashDensityColorProcessor::HashDensityColorProcessor	(	const SpatialHashConfig &	config,
		std::shared_ptr< Nodes::Network::GpuFieldOperator >	particle_op
	)

Parameters

config	Grid parameters, shared with the build stages that must already have populated hash_cell_start/hash_cell_count/ hash_particle_index this cycle.
particle_op	Owning operator. Colour word offset is resolved from its vertex layout (DataModality::VERTEX_COLORS_RGB) at construction; throws std::invalid_argument when the layout carries no colour attribute. density_saturation_count is re-read from this operator's config whenever revision() changes.
