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

Source: Hacker News

Overview

I created a site that lets you draw directly on street‑level panoramas. Your drawings persist, and other users can see them in real time. Strokes are projected onto the 3D panorama, so they wrap around buildings and follow the geometry rather than being a flat overlay. The implementation uses WebGL2 for rendering and Mapillary for the street imagery.

The goal is to turn the world into a global canvas where anyone can leave a mark anywhere, and others can stumble upon it.
