Experimental mosaic tool

Delaunay Mosaic

An experimental online tool that builds mosaic-like images from triangular Delaunay tessellations instead of a regular tile grid.

Experimental — workable, but not a production product

A different geometry

Classic tessera mosaics place tiles on regular rows and columns. Delaunay Mosaic triangulates the image: regions become triangles whose density follows the detail of the source picture, producing a faceted, crystalline interpretation.

Delaunay and Voronoi — one geometry, two views

Delaunay triangulation and the Voronoi diagram are mathematical duals: they come from the same seed points, and each can be converted into the other. Every Voronoi cell surrounds one Delaunay vertex; every Delaunay triangle corresponds to one Voronoi vertex.

The two tools therefore read the same image through complementary geometry — triangles in Delaunay Mosaic, cells in Voronoi Mosaic. If a composition almost works in one, it is always worth checking its dual in the other.

Status and scope

This is an experimental but workable tool. It explores mosaic geometry beyond the production grid and is not a substitute for the main Tile Mosaic Maker software: it does not produce production workplans, and its output is not aligned with physical tile assembly workflows.

Example output

Sunflower rendered as a Delaunay triangle mosaic, with seed points visible in the unfinished area — A sunflower emerging from its seed points — triangle density follows the detail of the source image.

Poppy flowers rendered as a colorful Delaunay triangle mosaic — Poppies as a field of color-graded triangles: smooth areas stay coarse, edges go fine.

Portrait rendered as a fine Delaunay triangulation with uniform mesh density — A portrait study at fine mesh density — the triangular grid reads like engraved line work.
