Some #mathart from 2001.

Typical visualizations of surfaces I would see back then were boring, angular, and sameish -- they used the same default Mathematica colors, and the polygons were visible. (Google image "Mathematica surface graph" to find this style.)

Just like these typical graphs, this rendering method is based on triangles; however, as long as the triangles had >1 pixel, they are recursively subdivided -- and eventually single pixels are colored according to a formula.

#mathviz

If they expand in the same 'z' direction, but with different rates instead, it looks more like a horosphere (compare the first visualization in this thread); this is why hexes in the visualization below are squished when we look at them orthogonally from far away. #mathart #noneuclidean #hyperrogue #rogueviz #mathviz #visualization
