Refine profile dot-art: levels, edge-aware density, fg/bg motion#75
Merged
Conversation
Consolidates the dot-art refinements that followed the initial version (PR #72) into one change against master: - Highlight handling: a "levels" rolloff (HL_DIM/HL_POW) dims the brightest tones before stippling, plus a brightness cap (CAP_OUT ~80%) applied outside a face ellipse so the bright t-shirt no longer out-shines the face or saturates (it was blowing out at phone size). - Edge-aware density: density mixes tone with a blurred Sobel edge field, rho = tone^GAMMA * (FLAT_BASE + EDGE_GAIN * edge), so information-rich regions (face/hair/beard/collar) get many more dots than the flat t-shirt. - Foreground/background split: a flood fill of dark pixels from the image border separates the subject from the near-black backdrop (no transparent PNG needed); each point carries an fg flag (points file is now stride 4). - Background motion: background dots breathe much harder than the figure, swelling and contracting about its centroid, while the figure keeps its spring + curl shimmer + gentle breathing + cursor repulsion. Generator (research/profile-dots/stipple.mjs) is deterministic and reproduces the committed points.json. tsc + lint clean.

Consolidates the dot-art refinements made after the initial version (PR #72, now on
master) into a single PR againstmaster. All verified headlessly.Highlights / saturation
HL_DIM/HL_POW) dims the brightest tones before stippling.CAP_OUT≈ 80% of the in-face max) applied smoothly outside a face ellipse, so the bright t-shirt no longer out-shines the face or saturates — it was blowing out to a white mass at phone size. Measured face vs. body brightness to confirm the body is no longer brighter than the face.Edge-aware density
Density mixes tone with a blurred Sobel edge field:
so information-rich regions (face, hair, beard, collar) get many more dots than the flat t-shirt, while tone still gates the figure against the empty background.
Foreground / background split + background breathing
public/img/profile.pngwith real alpha is added later, the generator can prefer it). Each point carries anfgflag; the points file is now stride 4 (x, y, b, fg), and the component stays backward-compatible.Notes
