I’m proud to announce that my friend Simon Mulser and me released https://app.shadowmap.org today
Without Three.js it would probably not exist. It was in the works for two years and there is a big accompanying post over at Product Hunt Shadowmap - Interactive 3D maps app to visualize solar shadows worldwide | Product Hunt
Technically it works but there is much to improve – I’m aware of quite some issues But it’s been a big step to release it and work on from there.
I’m grateful for your feedback!
