Colored balloons in Sol geometry, stretched by exponential expansion and contraction
Raymarching in Sol geometry, a solvable Lie group that is one of the eight Thurston model geometries. Colored balloon spheres are placed in the space. Sol has two expanding and one contracting direction, causing objects to appear stretched in characteristic ways. Geodesic computation uses the Sol exponential map.
