Claude AI Agents Build Explorable 3D City Models Using Three.js

An open-source project uses autonomous Claude 5.1 agent swarms to research, model, and validate browser-based 3D reconstructions of real-world locations, starting with San Francisco's Union Square. The system generates buildings, storefronts, traffic, and pedestrians from open data like OpenStreetMap and public imagery, packaged as runnable Three.js applications rather than relying on a game engine or proprietary 3D tiles.

How 2004's RuneScape squeezed a 3D multiplayer world onto 56k dial-up

A technical retrospective examines a decompiled 2004 RuneScape 2 client to explain how Jagex packed a 3D game world with up to a couple thousand concurrent players onto connections as slow as 5 KB/s. The analysis traces a single player movement command byte-by-byte from click to server to another player's screen, revealing the extreme data-efficiency techniques used. These core network principles reportedly persisted from RuneScape Classic through to Old School RuneScape and RuneScape 3 today.
