Show HN: I Was Here – Draw on street view, others can find your drawings

15•mrktsm__•2h ago

Hey HN, I made a site where you can draw on street-level panoramas. Your drawings persist and other people can see them in real time.

Strokes get projected onto the 3D panorama so they wrap around buildings and follow the geometry, not just a flat overlay. Uses WebGL2 for rendering, Mapillary for the street imagery.

The idea is for it to become a global canvas, anyone can leave a mark anywhere and others stumble onto it.

I love it until fine I'll signup and love it again but then no you pay now. My 2 cents is all I have to give.

I hear you on the friction. I’m experimenting with the 'ink' limits right now, also the ink actually regenerates. I think I need to make it more obvious in the UI

Good fun thanks! Found a cute cat in Buenos Aires. It seems you have quite a lot of activity already, is that all from HN in the last two hours or from something else before this?
