Author here--This is a follow-up to my last post, here: https://news.ycombinator.com/item?id=17065264 https://news.ycombinator.com/item?id=17065264 The feedback in that thread was great, and I ended up implementing several of the suggestions given in the comments. Thanks for all the help!

Are you aware of the work that has been done with shaders to trace through depth maps in real time? http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.138.1793&rep=rep1&type=pdf http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.138... This shows relaxed cone mapping, which is a very elegant and effective optimization.

  I have indeed! HN user "CyberDildonics" commented with a link to it in the original post. Would be useful if I ever move from bilinear interpolation to determine surface intersection to tessellation.

I share your awe at the Vatican map gallery. Two stories high, floor to ceiling, 400 hundred year old hand painted maps, for the entire length of a football field. And it’s not just the size, it’s the detail and joy put into maps of little places that no one outside has ever heard of. I’ve never found photos online that half show how awesome the map gallery is. If I ever get back to the Vatican, I plan on spending 90 of my time there.

  It really was fantastic! If it wasn't for the massive crowds constantly pushing you towards the Sistine Chapel, it would be a great place to spend an hour or two just admiring the small details in each map.

If you have a thing for Lake Mead then you really need to read the Edward Abbey books Desert Solitaire and The Monkey Wrench Gang. Very beautiful part of the world and I am glad to see you have a passion for getting the maps right.

  I'll be sure to put it on my list! The American west's landscape is just incomparable to anywhere else in the country. I'm an east coaster myself, but nothing out here compares to the beauty and grandeur of the canyons, mountains, and gorges you find out west.
