Houdini 20.0 Nodes Geometry nodes

Labs Extract Borders geometry node

Extract curves from Meshes

This node converts models to curves, either by extracting the mesh boundaries as curves, or by splitting every point and outputing a wireframe version of the mesh.

This is a simple wrapper around the Divide node, which isn’t very discoverable. As well as vertexSplit and facet to provide additional functionality.

Parameters

As Curves

Unroll the Mesh and delete all primitives.

UV Borders

Toggles between outputing the geometry boundaries vs the uv boundaries.

Split All Points

If outputting the geometry boundaries, split the mesh into all unique faces, which in turn gives you a wireframe representation of the model.
