I made a web app to generate 3D models of real places on earth from land cover and elevation data. Click anywhere on the map to get a polygon, and then click "generate". It should work at most scales, but if your watershed or region selection is too large, the result can be less exciting because it's so flat. As a warning, the 3D models can sometimes be too much for my phone. It's nicer on desktop. I'm still working better on mobile support. The land cover data I'm using gives a cool effect, but at some point I'd like to add in global imagery and clouds. The backend is a Python thread…

Get any piece of Google Earth as a single normalized glTF 3D model2023 · github.com · ▲177Google released an API in May to get fetch 3D Tiles of anywhere on Earth. Using this in standard 3D engines like Blender is tricky because (1) the tiles are in a geographic coordinate system (2) you get a lot of little tiles at varying quality levels I wanted to simplify this so all you need to do is get an API key, select a map region and a zoom level, and get one combined glTF file that you can throw into any engine. Especially if you're just prototyping and want to see how this data looks in your engine before investing in figuring out all the nuances of the API & coordinate system. (Note…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
