Neon Grid — Open World Driving Prototype

An original, browser-based open-world driving prototype built with Three.js + TypeScript. Inspired by the gameplay feel of open-world action games — not using any copyrighted assets, code, characters, or maps. Everything (city, vehicle, physics, UI) is generated/coded from scratch.

Features (current prototype)

• Procedurally generated 5×5 city block grid with roads, lane markings, buildings, and streetlights
• Full day/night cycle with dynamic sky, fog, and sun lighting
• Arcade-realistic vehicle physics (engine force, drag, grip, handbrake slip)
• Smooth third-person chase camera
• Custom HUD: speedometer, in-game clock, hexagonal radar, wanted-star indicator

Tech stack

• TypeScript
• Three.js (rendering)
• Vite (build tool / dev server)

Getting started

npm run dev

Open the printed local URL in your browser.

Controls

• W / A / S / D or arrow keys — drive
• Shift — handbrake
• Space — brake

Build for production

npm run build
npm run preview
