Query: An algorithm for two-dimensional mesh generation based on the pinwheel
  tiling   We propose a new two-dimensional meshing algorithm called PINW able to
generate meshes that accurately approximate the distance between any two domain
points by paths composed only of cell edges. This technique is based on an
extension of pinwheel tilings proposed by Radin and Conway. We prove that the
algorithm produces triangles of bounded aspect ratio. This kind of mesh would
be useful in cohesive interface finite element modeling when the crack
propagation pathis an outcome of a simulation process.
