Atelier Table

Digitize paper patterns and project layouts onto fabric.

The cutting mat is the ruler. Three printed A4 CalSheets teach the software what that ruler actually measures. A webcam and an optional cheap projector do the rest.

This is product 1 of Atelier.

Product	Repo	Role
Table	this repo	Paper ↔ cloth, in millimetres
Studio	atelier-studio	Offline drape and render
Looking Glass	atelier-looking-glass	Photo / short-clip try-on
Draft	atelier-draft	Live CAD + libraries + Commons

Table produces garment.v1 IR and an evaluated .sm2d. It does not simulate cloth, try clothes on a person, or own live formulas. That last job is Draft.

Who it is for

You, standing at a cutting table. You have a self-healing mat, a laptop, a USB webcam, and maybe a mini projector. You do not want to tape A0 PDFs together, and you do not want to re-digitize a traced block by clicking a hundred points.

What you can do now (web v0)

A working browser loop exists (TanStack / TypeScript). It is the app you can use today:

1. Print CalSheets — A, B, C as real SVG files, plus a print layout. 100%. Do not fit to page.
2. Calibrate — photograph the empty mat (upload or device camera). Click four corners and the 100 mm bar. Optional: read grid pitch from the photo lattice. Residual in millimetres. Save board.v1.
3. Sheets come off — the lamp can draw the board grid from the measured pitch. You do not leave CalSheets on the fabric.
4. Digitize — white paper on the mat, trace or click a contour, or import SVG / garment.v1. Export JSON, SVG, or evaluated .sm2d.
5. Project — pieces on the photo, or lamp mode. Second window/tab is the projector output (same session). Drag, rotate, flip, keystone.

The long-run product is still a Rust daemon that owns the webcam and the projector display, with the browser as a remote. See docs/ARCHITECTURE.md and docs/WEB.md.

How you run the long-run binary (not built yet)

# on the laptop next to the table (owns the webcam + projector)
atelier-table serve --bind 0.0.0.0:8080 --open

Status

Layer	State
Contracts	board.v1, garment.v1, CalSheet v1
Web v0	Working loop in the App Builder preview (calibrate → digitize → project). Source not vendored here yet — this repo stays the product home and the spec.
Rust daemon	Not started. Still the target for hardware ownership.
