From the README

Personal site of Allan Hert, founder of Hertwave. Two things live here: a selected-work portfolio, and a Lab of interactive WebGL experiments that run live in the browser.

Reaction–diffusion (src/lab/reaction-diffusion/) — Gray-Scott run entirely on the GPU with ping-pong framebuffers. Two chemicals, one feedback loop, emergent pattern. Drag to seed the field.

Raymarched field (src/lab/raymarch-field/) — an SDF isosurface marched per-pixel and lit in real time in a single fragment shader. The cursor bends the distance field.
