Horosphere lattice in hyperbolic 3-space with cusp acceleration for efficient raymarching
Tiling of hyperbolic 3-space by a cubic fundamental domain, with horospheres rendered at ideal vertices. Uses the hyperboloid model with the Lorentz inner product, and implements cusp acceleration for efficient raymarching near ideal points where horospheres accumulate. Phong lighting with multiple point lights.
Controls: WASD to rotate, arrow keys to translate.
