Relativistic and non euclidean space rendering

The Portal series built a full game concept out of non euclidean spaces. Besides being great games, I think it is fascinating how true the tagline “Now you’re thinking with portals” is.

Here are two interesting experiments putting the person in different spaces than we are used to due to real world conditions. This video by Varun Ramesh demonstrates a non-euclidean ray tracer:

This other video by the MIT Game Lab demonstrates OpenRelativity, a Unity toolkit allowing simulation of navigation at relativistic speeds, used for the prototype game A Slower Speed of Light:

Update: Sylvain mentioned in comments that Carl Sagan explains those effects in the following video:

    • Thank you for the link, it’s a good watch.

      OpenRelativity is the engine they made for the game; I’ll clarify it.

  1. I’d like to try more non-euclidean 3D games. It’s great to train the mind to grasp an intuition of how it feels like to move in a spatially different world.
    Some games like this already exist, but I have not played them yet.
