SpiroFieldInteractive Digital Spirograph
SpiroField is an interactive digital spirograph for drawing layered hypotrochoid and epitrochoid curves with tactile ring, wheel and pen-hole controls.
How the process works
Choose a fixed ring, rolling wheel and numbered pen hole, then run the virtual mechanism inside or outside the ring. Lab controls introduce repeatable gear slip, backlash, wobble, pen flex and other physical irregularities.
Inputs and source material
Start with the built-in rings, wheels and pen holes, then choose line color, width, opacity, canvas and mechanical character.
Save and export
Save editable SpiroField projects and export finished artwork as high-resolution PNG or genuine vector SVG. Live drawing can also be recorded from the output canvas.
- 01Choose a ring, rolling wheel, pen hole and inside or outside drawing mode.
- 02Press Draw to watch the mechanism, or complete the curve instantly; layer additional patterns and use Lab controls for mechanical variation.
- 03Set the canvas and export size, then save the composition as PNG or vector SVG.
