Pattern generator

Truchet tiles: one tile, endless patterns

In 1704 the French priest and scientist Sébastien Truchet published a study of the patterns you can make with a single square tile split diagonally into two colors, simply by rotating it. Much later, the metallurgist Cyril Stanley Smith popularized a variant with two quarter-circle arcs, whose curves join from tile to tile into continuous, winding lines.

The idea is the basis of a lot of generative pattern work: one simple tile, a rule (or chance) for how it is rotated, and a surprisingly rich surface. Diagonals give mazes, arcs give flowing, organic lines, quarter circles give bold, blocky compositions close to Bauhaus graphics.

How this pattern generator works

The tool lays a grid of tiles over the frame and picks the rotation of each one. With Order at zero the choice is random; as you raise it, a noise field takes over, so neighboring tiles agree and the pattern becomes structured, with larger shapes and channels.

• Style: arcs, diagonals, triangles or quarter circles.
• Size and Weight: the tile size and the line thickness.
• Order: from random to guided by a noise field.
• Accent share: how many tiles take the accent color.
• Seed and Generate: a new pattern in one click.
• Background, Stroke and Accent: the three colors.

Two more pattern tools

Cross-Stitch Tile, the tool of the cross stitch pattern generator page, builds a symmetric two-color chart filling the frame: borders, corner flowers, a diamond band, scrolls and a central rosette, each with its own controls. Mirror Pixel Totem, on the pixel art pattern generator page, builds four-way symmetric pixel art and lets you paint new zones with a mirrored brush. Both pages are linked under More tools.

What designers use it for

• Packaging, wrapping paper and labels.
• Wallpapers and backgrounds for websites, slides and apps.
• Textile and print-on-demand patterns.
• Brand systems where one tile family, in brand colors, gives endless variations.

Tips

Start from a preset (Maze, Organic or Bauhaus) and change one control at a time. Large tiles with a low accent share look calm and graphic; small tiles look like texture. Raise Order slowly: between about 0.6 and 0.9 the pattern keeps some surprise while showing larger structures. Use Generate to browse quickly, then note the seed of the one you like.

Describe the pattern you need

Wallpaper repeats, packaging patterns, textile charts, tile layouts: describe one and Blueprint builds the generator with presets and a Generate button. Vector tools also export SVG, which keeps lines sharp at any size.
