Agent autonomously replaces Gazebo's Ogre rendering engine with Filament in 36 hours

facontidavide · x · 2026-11-12

facontidavide had a coding agent replace Gazebo's Ogre rendering engine with Google's PBR real-time engine Filament. Running 24h/day for 36 hours, the agent produced a fully functional drop-in replacement: all simulated sensors work and rendering is faster. Comparison shots show clearly better PBR materials, and the PR is up on gz-rendering — another strong data point for agents doing large-scale refactors in real codebases.
