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

36 pointsby mrktsm__today at 5:04 AM27 commentsview on HN

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.

Why are places marked which have zero strokes? Why is the heatmap activating for places without strokes? Is something going wrong?

It's not very obvious which places are available for drawing. At first I thought it pulls Google street view, so I just zoomed in to some place I visited recently, but there was nothing.

So it turned out the spots on the map are actually the available panoramas, and not just a heatmap of the signatures.

Cool idea overall!

Cool idea, but of course the very first image I clicked into was a dick.

It is my belief that a time may come when we can all ‘write’ on, or link information to, any person, place, or thing, based on a melange of semantic anchors, and in that world there will be fewer secrets and more experts.

A long, long time ago ... there was a browser extension or maybe an iframe, that allowed you to "comment" on public websites. Of course you weren't really commenting on the actual website, just some form of overlay. Anyway, it quickly devolved into lawsuits and rude comments if I recall correctly.

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?

How are the panoramas chosen? That is, can I select one that isn't currently on the map?
