How the Contour style works

Contour treats brightness as height and traces iso-lines through it with marching squares, like a topographic map. Coverage sets how many levels are traced, from 3 to 12.

Best for

Maps, data-art and minimal line graphics — especially with shaders.

Tips

  • Try it with the Drift or Swell shader.
  • More levels, more lines.
  • Export SVG for plotters and laser cutters.

Export

PNG, JPEG, WebP and SVG. Animated looks export as GIF, MP4 or WebM.
