Expand description

An edge, which connects two Nodes in a RenderGraph.

They are used to describe the ordering (which node has to run first) and may be of two kinds: NodeEdge and SlotEdge.

Edges are added via the render_graph::add_node_edge(output_node, input_node) and the render_graph::add_slot_edge(output_node, output_slot, input_node, input_slot) methods.

The former simply states that the output_node has to be run before the input_node, while the later connects an output slot of the output_node with an input slot of the input_node to pass additional data along. For more information see SlotType.

Variants§

§

SlotEdge
