My 30 entries for #30DayMapChallenge 2023. Managed to do all save one (Day 5) with #rayshader, #rayrender, or #rayvertex in #rstats. Made possible by @tylermorganwall, who's created a marvellous world of light and shadow accessible with a language that's "only for stats".

Here are three takes on John Snow's iconic visualisation of cholera in 1854 London, all done in the #rayverse. Which one do you prefer—illuminated globes (left), lines (top right), or cel-shaded globes (bottom right)? I can't decide.

A 5x improvement in rayshader's software rendering speed ain't too shabby...

Context: My original software rendering implementation was a quick-and-dirty hack that took advantage of the fact that I had already written an OBJ exporter and my software renderer had an OBJ importer, so I could link the two with little additional effort by writing/reading the scene to the filesystem. With caching it was okay, but that initial write could be painful for big 3D models.
