:alt: Dual Mesh node.
The *Dual Mesh Node* converts a mesh into its dual, i.e. faces are turned into
vertices and vertices are turned into faces. This also means that attributes
which were on the face domain are transferred to the point domain in the dual mesh.
.. warning::
The Dual Mesh node only works on manifold geometry. To work with non-manifold geometry
it's best to remesh the geometry first.
Standard geometry input.
Keep Boundaries
Keeps the non-manifold boundaries of the input mesh in place, by creating
extra geometry, and avoiding the dual mesh transformation there.
This node has no properties.
Dual Mesh
Standard geometry output.
The *Dual Mesh Node* combines nicely with triangulated meshes. In this case
an Ico Sphere is used, which is made up of nice and evenly spaced triangles.
