Two spheres in Nil geometry, with helical geodesic distortion

Raymarching in Nil geometry, a nilpotent Lie group that is one of the eight Thurston model geometries. Two spherical objects are placed in the space. Geodesics in Nil are helical curves, causing straight-looking paths to twist. The Nil metric is computed via the nilMatrix construction. Controls: WASD to rotate, arrow keys to translate.
