This is a higher-resolution version of the Euclidean connect-sum-of-tori raymarcher. It renders the interior view of a flat 3-manifold built from identified tori, showing the tiling of Euclidean space by copies of the fundamental domain. The increased resolution reveals finer detail in the recursive reflections and the topology of the manifold’s universal cover.
Controls: WASD to rotate, arrow keys to translate.
