Felt 3D style, in testing: needle-felted wool puppets raymarched in WebGL2 (a halo of stray fibres on every silhouette, heathered matte wool, glass bead eyes, stitched mouths and toes), rendered over a TRANSPARENT background so any backdrop (a drawn set, a photo, a video) can go behind, with the puppets' shadows caught on the backdrop's floor. Use it for needle felt, wool, plush, felt dioramas, «same characters on many sets» (green-screen style memes), or when working with styles/felt3d/.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Style · Felt 3D
Status: **in testing** (first use: `sandbox/2026-09-25-felt-cats/`, the «dancing cowboy
cats» in felt on swappable sets).
## Code
`styles/felt3d/felt3d.js` → `Felt3D.renderer(env, { scene, scale, params })` compiles the
scene's GLSL; `R.render(g, key, f)` pastes the puppets' layer (memoised per `key`: the
drawing index), `R.layer(key, f)` returns it. `f`: `cam, target, fov`, `zoom: [S, u, v]` (a
2D zoom about a point of the frame, exact and at full resolution: give the backdrop the same
transform), `light, keyCol, fillCol, key, fill, soft`, `shadow` (opacity of the caught floor
shadow), `floorY`, `p` (scene data, read in GLSL with `PF(i)`, `P3(i)`, `M3(i)`,
`local(p, o)`), `boil` (the drawing's variant: the fibres move per drawing), `debug`
(1 albedo — fast, for pose fitting —, 2 normal, 3 key shadow, 4 occlusion).
The scene GLSL defines `map(p) → vec2(distance, material)` (material 0 = a bound),
`albedo(m, p, n)`, `material(m) → (specular, shininess, wrap, fuzz)` (fuzz > 0 is felt: the
reach of its stray fibres in units, ~0.013; 0 is a hard material: beads, wire), and
optionally `#define FLOOR_DECAL` + `vec4 floorDecal(p, rd, L)` (premultiplied: a puddle, a

How to install
mdr add illodev/drawn-by-code/style-felt3d@sha256:89cb8a4027ec7a72The line at the top of this page pins the label git:20260926.66a91c5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
