Fig 3. Two-dimensional WM fibers are contained within the edge, e_ij (white pixels), connecting nodes (gray pixels), n_i and n_j, as labeled in Part A.

For straight-line edges, the fiber lies within pixels of the edge. The streamline tracks are shown in pixels of the edge performed with (B) one seed-per-pixel and (C) four seeds-per-pixel in a single-pixel edge, and (D) one seed-per-pixel in a two-pixel edge. (E) A fully connected 2D network with straight edges on each face of a central node, n_i (dark gray), connected to four other nodes (light gray), each through a single fiber (white) similar to the fiber shown in part B-D.
