3D Traffic Scenario Editor | Driving Theory Scene Builder

About This Product

We built a browser-based 3D Traffic Scenario Editor that lets driving schools and theory-test content teams construct realistic road scenes and export driver-view images for driving theory questions. Built with Three.js and WebGL, the editor runs entirely in the browser with no installation. Users assemble intersections from modular road pieces with automatic snapping, place vehicles, traffic signs, road markings, pedestrians and environment objects from a library of over 40 object types, switch weather and day/night, then jump into a driver-view camera with three live mirrors and a dashboard overlay. Scenes are saved as JSON, autosaved every five minutes, and exported as high-resolution PNG images up to 4K with optional transparent backgrounds. First delivered for a European driving-school client, the object registry makes it simple to add any country's sign set, vehicles or road modules without touching the core editor.

Developed Using

✓Three.js + WebGL for real-time 3D rendering directly in the browser with no plugins or installation.
✓Modular object registry where every road, sign, vehicle and prop is one factory entry, so new assets need no core changes.
✓OrbitControls and TransformControls for a familiar 3D editor experience with move and rotate gizmos.
✓Render-to-texture mirror cameras that draw the rear, left and right mirrors live inside the driver-view dashboard.
✓JSON scene serialization with save, open, autosave and restore, plus offscreen high-resolution PNG export.

Key Features

✓Build intersections from modular road pieces with automatic grid and road-end snapping.
✓Library of 40+ object types: roads, markings, vehicles, country-specific sign sets, pedestrians and environment props.
✓Driver view with in-car camera, three live mirrors, speedometer, speed slider and turn indicators.
✓Weather presets (Sunny, Rain, Snow, Fog) and a day/night toggle that update sky, lighting and fog.
✓Inspector and scene hierarchy for precise position, rotation, scale, naming and locking.
✓Undo/redo, duplicate, delete and keyboard shortcuts for fast scene editing.
✓Save and reopen projects as JSON, with autosave every five minutes and one-click restore.
✓Export PNG at 1080p, 1440p or 4K with an optional transparent background, ready for theory-test question sheets.

Business Impact

✓Cut the time to produce a driving-theory question image from hours of manual illustration to minutes in the editor.
✓Runs in any modern browser, so content teams need no software installation or licensed 3D tools.
✓Consistent, repeatable scenes: reopen a saved project and regenerate the same image at any resolution.
✓Extensible asset registry lets clients add country-specific sign sets and vehicles without redevelopment.
✓Delivered as a fully offline static package, deployable on itch.io, an intranet or any static host.
