I'm a dermatologist and I vibe coded a 3D biophysical skin model

In the maker’s words

I'm a dermatologist. A year ago I posted a skin cancer quiz I vibe coded with Gemini 2.5 Pro. A top comment said that was the limit of vibe coding. This year I tried something more ambitious: SkinLab, a biophysical model of human skin that runs in the browser using WebGL. You can cut it or wound it and it heals realistically to form a scar. Then you can treat the scar with laser and watch the healing process. - 1.2 million voxels (0.25 mm resolution) for epidermis, dermis and fat. - Spring lattice with a J-shaped collagen fibre law and tension along the skin's lines - Healing as coupled ODEs (TGF-beta, myofibroblasts, collagen, contraction) - One static HTML file, WebGL, three.js, no backend By accurate I mean the constants come from published papers and it reproduces biophysical behaviour, such as incisions opening more when made more across the skin's tension lines and offloading preve…
