get_vertex_layout()

Kakshya::VertexLayout MayaFlux::Nodes::Network::AssemblyOperator::get_vertex_layout ( ) const

overridevirtual

The universal Kakshya::Vertex attribute layout, vertex_count 0 when there are no items yet.

Every item's record shares one 60-byte offset table regardless of topology (only the scalar field's name differs), so the shape is knowable – and a render pipeline buildable – before the first item ever arrives; only the count is data-dependent.

Implements MayaFlux::Nodes::Network::GraphicsOperator.
