If you can picture the "2D grid" (QuadTree) in 3D that's exactly how we are rendering the geometry, it's called a Sparse Voxel Octree, it allows us to compute in 3D, like in games, simulations, modelling.

This is how we make games in Refuge Studios upcoming #voxel game engine called "Oasis"!

I've been trying to design a hoogle earth style app, but, instead of navigation services and 3d meshed terrain tou can explore in first person, I just want it to quadtree the textures on a sphere and clamp markers representing entities on that sphere, then apply vector physics to manipulate them and

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

3- This means quadtree level=10 (1024) will slightly undersample at the bulging points of the cube-sphere, but level=11 (2048) will oversample significantly everywhere.

4- So L10 with 192px it is (better fit than other combinations).

The code to handle the quadtree is 436 tokens so far (~5% of all tokens) but I still need to handle objects moving within the space and in an CPU and token efficient way. Then I can see how collision works out. No idea what I'm going to use it for yet, just learning. #pico8 #indiegame #gamedev

I had thought about using quadtree, and was going to see about having a go at implementing that after I got the globe in and first idea of chunking tested and then compare the two for speed. First the globe, then a shake to disturb the snow!

hell, graphics and to some extent sound aside, fighting games, shmups etc still only really need 90s hardware - and an understanding of spatial partitioning in a pinch

(yes, I've seen "cursed" hitboxes that were clearly just a quadtree encoding of something pixel perfect into AABBs)

Quadtreeは、データ構造の一種で、特定領域に詳細な情報を与えつつ、他の場所のリソースを節約するのに役立ちます。
このブログ記事では、関数型Quadtreeと、その可視化をClojureで構築する方法を紹介します。
カメラ（マウス）の位置に基づいて、Quadtreeを再帰的に分割し、最適な解像度で表示します。

A Quadtree is a tree data structure, which is useful for giving more focus/detail to certain regions of your data, while saving resources elsewhere. I could only find a couple tutorials/guides and both were imperative, so I figured it'd be fun to do a functional version in Clojure which runs in the browser.
