Ahah, I didn't see that it was a reply to your post, sorry for the confusion ^^
To respond to your post from 71 days ago, "Non Euclidean Room" was the only name my poor brain could come up when the ludum dare game jam ended late at night ... For a possible sequel, I worked on "scaling portals" when you connect portals of different sizes and could even do non uniforme scales. I also tested curved portals that would distord the world when you cross them. But all my tests where more about bending meshes than really bending the space.
Thank you for all the reading and links in your articles, I will read that with attention.
