  abstract = {This paper presents a method for simulating decorative tile
              mosaics. Such mosaics are challenging because the square tiles
              that comprise them must be packed tightly and yet must follow
              orientations chosen by the artist. Based on an existing image and
              user-selected edge features, the method can both reproduce the
              image's colours and emphasize the selected edges by placing tiles
              that follow the edges. The method uses centroidal voronoi diagrams
              which normally arrange points in regular hexagonal grids. By
              measuring distances with an manhattan metric whose main axis is
              adjusted locally to follow the chosen direction field, the
              centroidal diagram can be adapted to place tiles in curving square
              grids instead. Computing the centroidal voronoi diagram is made
              possible by leveraging the z-buffer algorithm available in many
              graphics cards.},
