LightBurn Shattered Mosaic SVG Generator

This version treats the design as a layered planar mosaic, not as independent polygons drawn on top of radial lines. The center spokes are solid. Each polygon ring is staggered relative to the next, and the connectors between neighboring rings are randomly omitted. A ring is allowed to bend only at a point where another cut joins it, or where it meets the rectangle boundary.

That means: no unexplained bends, no floating crack endpoints, no diagonal splitting of four-sided cells into adjacent triangles, and no requirement that every ring be connected to the next at every possible location.

Rectangle and Impact Settings

Rectangle width

Rectangle height

Units

Impact point X (%)

Impact point Y (%)

Center Spokes

Candidate spoke / junction tracks

These are possible junction locations. Not every track continues through every ring band.

Angular irregularity (%)

Trim rays inside innermost ring

Yes leaves the area inside the innermost polygon as one center piece. No keeps the center-origin spokes.

Staggered Polygon Rings

Number of polygon rings

Inner ring radius (% of corner radius)

Outer ring radius (% of corner radius)

Ring-to-ring angular staggering (%)

Higher values move ring junctions farther out of alignment with neighboring rings.

Ring radial irregularity (%)

Randomly Broken Ring-to-Ring Connections

Inter-ring connection density (%)

Lower values create larger irregular shards. Each ring band keeps at least 3 connectors.

Connection density variation (%)

Lets one ring band be more broken than another.

Output & Reassembly

Stroke width (mm)

Random seed

Save the seed to reproduce the exact design.

Number every piece

Numbers are vector strokes rather than font text, so they import cleanly into LightBurn.

Maximum number height (mm)

Numbers automatically shrink to fit smaller shards.

Mirror layout for back-side engraving

Mirrors piece positions while keeping the digits readable.

Mirror direction

Choose the direction you physically flip the sheet.
