Two modes, one canvas:
- 🎨 Scene mode — draw the scene. Topology-aware lanes, vehicles, and intersections. Export figures (SVG / PDF) or maps (OpenDRIVE, Lanelet2).
- 🎬 Scenario mode — make it move. Add events and triggers, press play — esmini-WASM runs it in the browser, PASS / FAIL verdict included.
- Topology-aware lanes — connections follow when you edit
- Lane tool — click a centerline, get both boundaries
- Map → lanes — trace real roads from satellite/OSM data
- Intersection & roundabout templates — one click
- Vehicles, pedestrians, signs, and more — a full driving-domain library
- Snap & point sharing — geometry stays connected
- Path footprints — auto-placed and style-synced
- Math (LaTeX) — typeset equations on the canvas
- Re-editable saves —
.drawtonomy.svgreopens with everything intact
