Planar and columnar surfaces in Nil geometry, shaped by the anisotropic Heisenberg metric
Renders XY-aligned planar or columnar surfaces in Nil geometry by adjusting the weighting coefficients in the distance function. The anisotropic fake distance of the Heisenberg group metric creates plane-like or column-like shapes depending on the mode. Uses 600 marching steps for the highly distorted distance field.
Controls: WASD to rotate, arrow keys to translate.
