Polychoron Explorer

4D geometry exploration sandbox that is built on a brand new realtime 4D perspective projection rendering engine. 

Player can select any of the 6 known regular 4D Polychorons. Object can be rotated in 4D space. Any cell can be painted or hidden. Polychoron can also be scanned and split into 2 non-regular polychorons to explore further. 

Display can be adjusted to allow better view of internal structure of the projection of 4D world into viewer's 3D hyper-plane.

Engine is developed for making a puzzle game which is currently work in progress and not available in this release. 

This project is in Early Access, pre-release stage on Steam and will only become available for purchasing after 9 April, 2026. For this reason I am uploading it here. If you'll have paid here, you can request (via email or personal message to the developer) a Steam key after it becomes possible to generate them.
