From photo to vector
Draw a photograph with a spiral.
Spiral FM art starts at the center and travels outward. Small vibrations along the spiral build the light and dark regions of your photograph into a continuous drawing.
How Spiral FM reads a photo
The generator samples image tone as it moves around the spiral. Dark areas increase the frequency of the oscillation; light areas leave a quieter line. Seen together, the turns suggest the original subject without placing the photograph inside the SVG.
A centered portrait with a clear silhouette is a useful first experiment. The spiral remains visible as a structure, so the result balances likeness with the rhythm of the line.
Tune frequency and wave height
Select Spiral FM Art in the studio. Start with the default settings, then adjust Dark frequency to change how tightly the line vibrates in shadows. Wave height changes the size of those oscillations.
Increase Detail for finer sampling, but watch the output size. If shadows merge into a solid mass, try a thinner line or lower contrast before adding more detail. Generate again after each change to compare the result.
Edit or plot the spiral
The exported SVG preserves a continuous geometric route, split into adjoining path chunks to keep large drawings manageable. It is not a collection of raster strips or an embedded photograph.
You can recolor the strokes and scale the artwork in a vector editor. Before plotting, check how your software handles adjoining paths and choose a pen width that leaves enough separation between neighboring turns.
