Subdivide Edges

This demo shows how to use a custom NodeDropInputMode for dragging nodes from a separate panel onto an edge.

More precisely, when a node is dropped onto an edge, a new node is created and the edge is split in two edges such that:

• The source of the first edge is the original source of the split edge and the target is the newly created node.
• The source of second edge is the newly created node and the target is the original target of the split edge.

Things to try

• Drag a node onto an edge and see how the edge is being split.

See the sources for details.
