Figure 1
The illustration consists of three sections, each labeled to represent different stages in a design and path calculation process. (a) The “design mask” is on the left, displaying a large square grid with smaller squares in a light green color. In the center of the grid, there is a large red rectangular area, which likely represents the selected region of the design mask. (b) The “L B path matrix” is in the middle, showing a similar outer boundary in light green, and the central part is shaded in gray. At the center, a rectangular matrix is shown, which consists of 6 columns and 5 rows. The matrix contains the following values: 1, 2, 3, 4, 5, 6 (top row); 116, 171, 170, 169, 168, 167 (second row); 115, 172 (third row); 114, 173 (fourth row); and 113, 174 (fifth row), arranged in a structured format. The matrix has an arrow pointing towards the boundary from the top left. (c) The “L B path” is shown on the right side, where a square grid, similar to the one in section (a), outlines a rectangular path. The path is outlined with both red and blue borders: the red border marks the inner edge, and the blue border marks an outer boundary. The L B path is visualized with sharp corners and straight edges, defining a clear rectangular path. This section also includes a grid of smaller squares that provides a sense of scale.(a) The design mask operator, (b) LB path matrix and (c) the corresponding LB path. Source: Authors’ own work
