Code: Nil Balls Light · 2020

Spheres in Nil geometry lit by a single point source, showing twisted shadow patterns

Raymarching in Nil geometry with spherical objects lit by a single point light. The non-Euclidean metric of Nil causes light to follow helical geodesics, producing unusual shadow patterns. This single-light version highlights the geometry’s effect on illumination. Controls: WASD to rotate, arrow keys to translate.
