Spherical Geometry Is Stranger Than Hyperbolic - Hyperbolica Devlog #2
Why Hacker News recommends it
Recommended among the nice visual explorations and tech demos of non-Euclidean geometry for games.
What it is
CodeParade's short devlog on how spherical geometry looks in 2D and 3D and why it feels so unusual, part of the Hyperbolica series on a non-Euclidean game.

Code Parade on Youtube has some nice tech demo for non-euclidean 3D game engine. "Non-Euclidean Worlds Engine" - [LINK] "Spherical Geometry Is Stranger Than Hyperbolic" - [this video]

There’s another game being developed in a semi-3D hyperbolic geometry called Hyperbolica. The dev makes some fantastic videos [1]. [1] [this video]

Hyperbolica is mostly about the opposite, a hyperbolic universe, but there may be some section to the game that will be in a spherical universe. There's definitely some devlog video set in a spherical universe: [this video] The end of the video suggests this will be in the final game, at least as the time that video's creation. In the meantime, the video I link is basically a video exploration of spherical geometry. One of the better ones, in my opinion, because it has "normal" objects in it, rather than floating heads or a ton of Earths or something. (Another amusing sidebar: As you can see in the video above, an inhabitant of that space would be naturally inclined to say the space curves in abo

Cool. It would also be interesting to see a hyperbolic snake. Reminds me of this video, where the dev compares spherical and hyperbolical geometries (albeit a dimension higher): [this video]
