We show that every orthogonal polyhedron of genus g ≤ 2
can be unfolded without overlap while using only a linear number of orthogonal
cuts (parallel to the polyhedron edges). This is the first result on unfolding
general orthogonal polyhedra beyond genus-0. Our unfolding algorithm relies on
the existence of at most 2 special leaves in what we call the “unfolding
tree” (which ties back to the genus), so unfolding polyhedra of genus 3
and beyond requires new techniques.
