Polychoron Explorer
Dive into *Polychoron Explorer*, a groundbreaking 4D sandbox game where you experience a 4D world through the eyes of an imaginary 3D-sensing creature. Built on a brand-new 4D rendering engine, the game lets you explore six known regular convex polychorons—such as the 5-cell, 16-cell, and 600-cell—from any angle, just like a true 4D being. Using advanced 3D projection techniques, the game translates complex 4D shapes into immersive visual experiences. Rotate objects along any of the six 4D rotation planes via keyboard, mouse, or controller. Customize your view by coloring or hiding individual cells, save your creations, and track cell movements or rings. The Scan mode lets you slice polychorons with 3D hyperplanes, revealing hidden structures and experimenting with custom geometry—though some features require programming skills. While currently a sandbox for open-ended exploration, future updates may introduce casual puzzle challenges. *Polychoron Explorer* offers.
