Wang Tiles

Angled Paths (2-corner Tilesets)

Wang 2-corner tiles usually show a present or an absent path, like this:

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15

Alternatively, we can denote the angle of the path, \ or / like this:

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15

Look carefully and you can see yellow corners have North-West South-East paths (\) and blue corners North-East South-West (/) paths. If the path does not extend into the tile, only a small triangle is drawn, so the design will match adjoining tiles correctly.

Stage Array

The tiles automatically tile correctly using the existing Wang tiling method. Quite a complex maze results, with complex interlocking islands. It looks like the back of a Printed Circuit Board, hence named PCB.

We could also use Wang edge tiles instaed of corner tiles.

Angled Paths (2-edge Tilesets)

Here is a 2-edge Wang tileset showing absent or present paths at each tile edge.

In this tileset design, we denote the angle of the path, \ or / like this:

0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15

You can see yellow edges have North-West South-East paths (\) and blue edges have a North-East South-West (/) paths.
