Edge to Spline

What is it about?

This page refers to the Edge to Spline node of the Scene Nodes system in Cinema 4D. It converts geometry edges into spline curves — making mesh structure available as splines within node setups or as a capsule in the Object Manager.

Note:There are also Cineversity videos for these special Node capsules, which demonstrate their practical use. Follow this link to the corresponding overview page.

This node can also be used as a capsule in the Object Manager, for example, to respond to an edge selection and generate spline segments from it. In the example shown below, the Border Selection Node was first used to save the selection of the open edges of a landscape as an edge selection. Edge to Spline then accesses this edge selection, and an Extrude object creates polygons along the Y-axis based on these splines.

Example scene in Cinema 4D using a border selection of a landscape to extrude the border edge loop.

Note:

Keep in mind that Edge to Spline cannot automatically create a closed spline from a selection of edges. Each edge becomes a single spline segment. For this reason, even when a closed edge loop is processed, a closed spline may not be created.
