Truchet tiles: arcs, mazes and split triangles

In your harnessProcedural textureMIT

Generate tileable maps of Truchet tilings: quarter-circle arcs with a consistent two-colour fill, random diagonal mazes or half-square triangles, as raised glaze, printed lines, metal inlay or cement tiles. Use for decorative floors, wall tiles, inlaid furniture, wallpaper and game backgrounds.

Limits. Three classic tile sets on a square grid; there are no multi-scale or winged tiles, and the diagonal maze has no region fill because its regions are not two-coloured by corner parity. Line relief is a rounded profile from the exact distance, with no bevel lighting or glaze pooling. The wood and cement grounds are light noise, not full wood or stone generators. Occlusion is a blurred-height estimate.
