*Proceedings of the 18th Annual ACM Symposium on Computational Geometry (SoCG 2002)*, Barcelona, Spain, June 5–7, 2002, pages 237–243. **Abstract**:- We present an algorithm to unfold any triangulated 2-manifold (in particular, any simplicial polyhedron) into a non-overlapping, connected planar layout in linear time. The manifold is cut only along its edges. The resulting layout is connected, but it may have a disconnected interior; the triangles are connected at vertices, but not necessarily joined along edges. We extend our algorithm to establish a similar result for simplicial manifolds of arbitrary dimension.
