Chaotic Pen

Upload a portrait. The system will detect the face, build a density map, and deploy a single chaotic pen to sketch it ā€” one continuous stroke.

āš” Speed & Motion

3?Maximum pen velocity. Higher = faster coverage, less detail.
100?How many pen steps per animation frame. Higher = faster drawing.
0.4?How chaotically the pen direction changes. Higher = more scribble.
0.02?Strength of the random drift force applied to the pen.

šŸ§² Error Attraction

0.08?How strongly the pen is pulled toward high-error (under-drawn) areas.
40?How far the pen looks to find under-drawn areas. Larger = smoother paths.
4?Pixel step size when scanning for error. Lower = more accurate, slower.

šŸŒŠ Flow Alignment

0.04?How strongly the pen aligns to facial contour directions.

šŸ”„ Dwell Looping

1.2?In dark areas the pen's wander tightens into loops. Higher = tighter circles in shadows.
0.02?Push pen away from already-saturated areas (error near zero).

āœļø Line Style

0.2?Line width in light areas.
1.8?Line width in dark areas.
0.03?Ink opacity in light areas.
0.7?Ink opacity in dark areas.

šŸ§± Border

25?Distance from edge where border push activates.
0.04?How hard the pen is pushed away from canvas borders.

ā± Error Decay

5?Radius around each drawn point where error is reduced.
0.008?How much error is reduced per stroke. Lower = pen revisits areas more.
