Very nice! Can’t wait to see that integrated on a live map :)
For borders and parent lookup I think that should work nicely, like you said it’s mainly translating coordinates and having that data already around by the time you need it. Worst case comes when you’re at a corner the parent tile
I also like the full sweep based approach. But I guess one advantage of using the depth buffer is you don’t need to worry about tile edges. Sweeping gets tricky to adapt when the hull can be spanning multiple adjacent tiles
The sun rising over Thor Peak, Auyuittuq National Park, Canada. It's using line sweep horizon tracking to compute ambient occlusion and physically accurate shadows together with relief shading, all packed into an RGBA texture. Pretty happy with the scanline algorithm, but the shading needs work.
Very nice one! One thing I wondered for shadows is whether it can be extended with soft shadows. Since the sweep can store distance to the peak it’s occluded from

Gumroad can also be quite nice for 3d assets/software tooling. Very quick page setup with drag-and-drop exe uploads.
