Neat. I did a related project a little while ago. I wasn't interested in how far I can see from everywhere, so much as what I can see from one place in particular.

So in mine you can click on a spot and it draws black lines over any land that is occluded by terrain, within 100km.

I am not sure if I'm experiencing what you describe. I just see a radiating circle of black lines, no matter where I click. I decided to click a local, notable "long line" viewpoint -- Lick Observatory outside San Jose. From here, on a clear day, you can see Half Dome in Yosemite, 120mi away. I still just see a black circle.

Heh, I almost hit back at the "in Rust" mention.

Would the end result have been different if it were done in python calling C libraries for performance? I strongly doubt it.
