I'm working on detailed 3d visualizations of streets using WebXR (A-Frame and three.js). Still "half baked" :)
Repo: https://kfarr.github.io/3dstreet/ Example use case: https://17thpreso.glitch.me/ Traffic signals WIP: https://aframe-ped-signals.glitch.me/
Would love to collaborate esp. with those interested in learning 3d web dev, urban planning, etc.
