SRPG - Super Random Polygon Generator

srpg generates simply-connected and multiply-connected polygons by means of a regular grid (with quadratic cells).

See the srpg* directories in /db/wip/polygons/random/ for polygons and /db/wip/polygons-with-holes/random/ for polygons with holes.

There are several variants:

• srpg_iso: orthogonal polygons.
• srpg_iso_aligned: orthogonal polygons on an integer grid.
• srpg_octa: octagonal polygons.
• srpg_perturbed: random polygons.
• srpg_perturbed_smo: random polygons with smoothed corners.
• srpg_perturbed_smr: random polygons with even smoother corners.
