Marble Image Generator 3
A quarry sample press that keeps cutting new stone on its own — hold it when you like a slab, then save it as a print-resolution PNG.
Marble Image Generator 3
The press runs on its own. Every one of the fourteen shape parameters eases toward a fresh random target, the noise field itself flows so veins migrate rather than merely reshape, and the palette cross-fades through twelve quarries with a pause on each — the slab is never the same stone twice. Hold freezes it and re-renders at full preview detail; Drift lets it move again. Touching any slider holds automatically, so an adjustment you make actually sticks.
Save PNG holds first, then re-renders exactly the slab on screen at up to
3840 × 2160. The renderer is resolution-independent — pixel geometry is measured
against a 720-line reference — so the file is the preview cut finer, not an
upscale. The export runs in time-sliced chunks with progress next to the buttons
and arrives as marble-3-<seed>-<palette>-<size>.png.
A seed is a whole specimen: the noise field, the palette and every parameter’s starting value. Generate draws a new one; typing a seed back in returns to that specimen’s canonical cut, from which drift departs again.
| Control | Effect |
|---|---|
| Palette | Twelve quarry palettes: base stone, vein, and capillary tint |
| Seed | The specimen itself — noise field, palette and every starting value |
| Scale | Zoom of the noise field; larger values mean broader figuring |
| Figuring | Strength of the cloudy mottling in the stone body |
| Detail | Noise octaves feeding the veins — smooth at 2, fibrous at 7 |
| Count | How many primary veins cross the slab |
| Sharpness | Vein width: broad washes at 2, hairlines at 40 |
| Turbulence | How strongly noise bends the veins off their axis |
| Warp | Domain-warp strength — parallel veins at 0, swirling stone above 1 |
| Spread | How much of the slab the veins are allowed to reach |
| Angle | Orientation of the primary veining |
| Capillaries | Strength of the fine secondary filaments |
| Pitch | Frequency of those filaments relative to the primary veins |
| Cross angle | Direction they cross the slab |
| Film grain | Speckle laid over the surface; scales with the export size |
| Polish | Strength of the specular sheen on the cut face |
| Drift speed | How fast the autonomous mode moves (does not hold the slab) |
