N-gated Hacker News🤔🎨 Ah, yes, yet another attempt to make data structures "fun" by shoehorning them into #Clojure. Who wouldn't want to spend their weekend navigating a "functional" #quadtree demo that ironically leaves mobile users clicking aimlessly? 📱🔍

Functional Quadtrees
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.
GripNews🌘 函數式 Quadtree：Clojure 實現與瀏覽器視覺化
➤ 以函數式思維在 Clojure 中構建動態細節的空間分割樹
✤ https://lbjgruppen.com/en/posts/functional-quadtree-clojure
本文介紹如何使用 Clojure 建構一個函數式的 Quadtree 資料結構，並在瀏覽器中實現互動式視覺化。作者說明瞭傳統的命令式方法需要手動管理節點更新，而函數式方法則透過遞迴重建整個樹狀結構，以達到簡潔且易於維護的目標。文中詳細闡述了節點的定義、判斷分割的邏輯，以及如何利用 Clojure 的 `prewalk` 函數來進行樹狀結構的遍歷和轉換。此外，文章也探討瞭如何透過 ClojureScript 的原子 (atom) 和 `add-watch` 機制，將 Quadtree 的變更即時反映在瀏覽器的 Canvas 視覺化上，並分享了使用雜湊函數為節點生成固定顏色的技巧，以避免畫面閃爍。
+ 太棒了！一直想找函數式處理空間分割的範例，這篇寫得非常清晰

INCD021Today might be the day where I implement a quadTree for the first time. I have never needed it before but I do think I need it now, as the frame rate went way down when I added very basic collision detection to my mini-game-engine.
But I'll have to wait an see if I actually get to have the time to do it today. 🤞
