Agent Rewrites Gazebo's Renderer in 36 Hours: 19,000 Lines Replacing Ogre with Filament
facontidavide · x · 2026-11-12
Developer facontidavide had his coding agent spend 36 hours round-the-clock replacing Gazebo's Ogre rendering engine with Google's physically-based Filament engine, producing a fully functional drop-in replacement. The diff spans 155 files with 20,866 lines added and 954 removed, including a 91-file Filament plugin, 17 material shaders, and 26 test files. All simulated sensors work, and rendering is faster than before—a landmark demo of agents handling massive refactoring tasks.
