I recently came across these fortification maps...

An SDF composed of rotated shapes, vectorized and duplicated into layered contours, featuring black, white, and accent-colored dashed strokes with pattern fills, and rendered as polygons in an SVG.

Features:

- contours (32 - 64, step: 4) - number of shape contours
- rects (4 - 64) - number of rectangles
- circles (0 - (64 - rects)) - number of circles
- triangles (remaining from 64) - number of triangles
- gap (0 - 4) - extra shape gap
- angle (-90 - 90, step: 15) - shape rotation angle
- resX (200 - 500, step: 100) - horizontal resolution
- resY (200 - 500, step: 100) - vertical resolution
- background (l: 0.8 - 0.9 / c: 0.25 - 0.3 / h: 0 - 360, steps: 3) - background color
- accent (l: 0.6 - 0.7 / c: 0.25 - 0.3 / h: 0 - 360, steps: 3) - accent color
