Details

A field of short grass runs out to a hazy horizon, dotted with dandelions in flower and gone to seed, all swaying slowly in the wind. The scene is drawn cheaply and the grade does the work: wash it out to black and white with grain and faded blacks, or turn it up to a vivid summer afternoon. Fog, a sunny day, a pale blue sky or night.

Payload
11.6 KB brotli for meadow.js, ittybitty-shader.js, runtime.js and pointer.js, measured at build time.
Resolution
Device pixel ratio capped at 1: the grain and fog hide the softness, and it halves the cost on high-density screens.
Frame rate
Display rate.
When unseen
Stops rendering when the canvas leaves the viewport or the tab is hidden, and resumes where it left off.
Reduced motion
Shows a single still frame. Controls still update it.
Layers
Up to five effects fuse into one shader and one draw call. Filters such as dithering and halftone process the layers beneath them.
Browsers
Any browser with WebGL2: Chrome and Edge 56+, Firefox 51+, Safari 15+.
Licence
