🤔 I tried simulating how day/night & seasonal cycles wud work on a 4d planet, ðe surface gets projected using a hopf map, wiθ ðe zw direction mapped to color

1 year = 48 "days"(xy-plane planetary rotations)
ðe planet also spins in ðe zw plane once every ~2.526 days(19 times per year)
& ðere's a 72° yz "axial tilt"(orbital plane vs planet's xy plane)

🤨🤨🤨

🌘 Lift4D：調和單視角 3D 估計以實現野外環境下的 4D 重建
➤ 突破遮擋限制：從單目影片建構完整的動態 3D 世界
✤ https://lift4d.github.io/
Lift4D 是一項創新的測試時優化框架，旨在解決單鏡頭影片中動態物體的 4D 重建難題。面對複雜的野外場景（如大變形與嚴重遮擋），傳統方法往往受限於訓練數據不足或對初始化的依賴。Lift4D 透過因果潛在空間調節（causal latent conditioning）產生時間一致的幀級 3D 估計，並將其轉化為可變形的 3D 高斯噴灑模型。該系統利用遮擋感知優化技術，既能精確還原可見細節，又能透過視角條件擴散模型（view-conditioned diffusion prior）「腦補」出未觀測區域的完整幾何與外觀，實現了極具一致性的 4D 重建效果。
+ 這項技術在處理嚴重遮擋物體時的表現令人驚艷，以往的 3DGS 方法在面對背景遮擋時經常產生殘影，這篇論文提出的擴散先驗似乎是一個關鍵突破。

🤔 2.0, ðe d-block seems to form 2 false periods(4 some assumptions about how it cud work), so it's like a mix of lanθanides/actinides & some g-block predictions😳
Also Nitrogen needs to be s2p4 to form N2,
CO2 wud need to be weirder like carbon monoxide irl, or replaced by HCO2 / C2O4 / C2O5 / C(OH)O2 / 😖

& ðen ðere's ðat θing between N & O, ðat you'd expect to be abundant & form volatiles & get incorporated into biology somehow, which is a bit concerning

#ScreenshotSaturday except I'm actually #worldbuilding #4d #chemistry instead of reigning in ðe complexity creep🤔🤔🤔
Whatever,
p orbitals have 8 electrons because ðere's 4 directions,
& d orbitals will have 18‽ electrons(because of hyperspherical harmonics, obviously), so I'll be making ðem more like lanθanides & just skipping normal metals🫪

my idea for a #4D #factoryGame would be that "buildings" are (largely?) non-oriented and just input on ingoing belts and output on outgoing belts, similar to how Mindustry does it, no need to mess with inserters, etc.

building would happen from "god's eye view" like in shapez (2), but i do like the idea that you build the parts of your own factory. so you'd probably throw the finished parts into some central nexus and can place them from there.
