The Jacobi Solver is finally functional with diffusion transfer across quadtree nodes!🌟
The quadtree structure is visible through the diffusion, as it's dependent on the resolution.
Will try to limit this by tweaking some parameters

A joint paper by UTokyo and Game Freak (img 1), published in 2025-08, is possibly the technical underpinnings beneath the “nice water” in Pokémon Winds/Waves.
To improve rendering speed and reduce memory footprint, it uses a grid of quadtree tall cell to simulate deep water (img 2; columns 3-4).

Implemented a proper texture atlas based on quadtree subdivisions. It introduced leaking due to bilinear sampling (especially noticeable on grass), so I had to add some code to clamp texture coordinates based on actual atlas part used & on mipmap level.

Roughly speaking, areas with complex waves are divided into smaller cells, while calm water is represented by larger cells (img 1). A “variational [water] pressure solver” is devised to calculate fluid motion with the variable cells (imgs 2-3).

Revisited perspective-relative terrain gen in Unreal Engine, this time using a moveable quadtree to manage tiles. To test it out, I set up an auto-running character and let them run at the default third person template movement speed, and sent them on a 100KM jog! www.youtube.com/watch?v=W7pO...

Unexpected path. Draw a route that changes direction based on one very simple rule.
Quadtree subdivision + left/right turning agents. Catching up with #genuary.

me: you sure I don't want a quadtree for this?
Claude: yes, you want an R-Tree
me: well, you're the world's most advanced LLM, ok
Claude: here's the several hundred lines of code
