20-Year Engine Veteran Builds SF Bay Area Digital Twin from Scratch Using AI
julianharris · x · 2026-08-14
A veteran engineer with 20 years of AAA game engine development experience showcased a project written entirely with AI assistance in C++ and Vulkan: a real-time stylized digital twin of the San Francisco Bay Area.
Covering an 80 km square area, all geometry is built from open data (such as USGS terrain data, NOAA bay floor data, and OpenStreetMap roads). The author states the goal was to read as a painted model of the Bay rather than a photorealistic copy. Commenters noted that using AI to amplify core human skills is the best way to leverage the technology.
