Average monthly precipitation of the world, 1970–2000 #rayshader adventures, an #rstats tale

Today's basin is the Yangtze. #rayshader adventures, an #rstats tale

And again with more sunshine.

Okay I'm getting this into #rayrender immediately

The Mississippi basin. #rayshader adventures, an #rstats tale

Another day, another basin: the Mekong basin. #rayshader adventures, an #rstats tale

Writing technical blog posts about my packages is such a slog: not due to the actual writing process (which is fun!), but because I always uncover something weird and unintended in one of my #RStats packages that ends up instigating a massive rewrite somewhere. Can you spot the issue below?

Watch as a massive crack forms in the ice on Lake Erie. An impressive view captured by GOES-19 earlier on Sunday.

Obviously I'm in the #RStats cluster, but my favorite find is the small fungi enthusiast cluster (unlabeled but annotated here), which seems to have naturally formed a fairy ring (en.wikipedia.org/wiki/Fairy_r...) around its members. Beautiful.

"Animated Bokeh" has been on my whiteboard for a long time, and this is the result. I thought it would just be for cheesy novelty effects, but it also does lightfield manipulation that was cooler than I expected. www.youtube.com/watch?v=Kg_2...

The Congo basin. #rayshader adventures, an #rstats tale

The Ganges–Brahmaputra basin. Have another version that includes even more rivers but that's taking forever. #rayshader adventures, an #rstats tale

Nice, figured out how to fetch some Arctic DEM data, fill in the gaps with Copernicus GLO-30, run it through rio-tiler, and connect a WebGPU viewer with some basic level of detail refinement.

The Amazon basin. Been wanting to do this for a while and finally managed to fix the errors I was getting. I rather like how it turned out. #rayshader adventures, an #rstats tale

Power lines (OSM and derived) of Vietnam. #rayshader adventures, an #rstats tale

That was fast! Nice work, @etiennebacher.bsky.social!

It will make it in the update:

Thought of the day: You should be able to turn re-assignment of a `for` loops control variable into an error. E.g. for(i in seq_len(10)) { for(i in seq_len(5)) { ... } ...whoops! code here has i = 5... } "Error: reassignment of for loop iterator `i` detected" #RStats

New post: the design behind secretbase, a 40KB streaming hash package I maintain. The entire source package is smaller than most hex sticker PNGs. Hash large objects with constant memory. Powers targets pipelines. Plus CBOR encoding comes to R. shikokuchuo.net/posts/28-int... #RStats #OpenSource

Happy Groundhog Day! In honor of the day, here's an infinitely repeating video of a realistic atmospheric simulation showing the shadows the sun casts on February 2nd. (over Monterey Bay, California, because no one would want to go to Punxsutawney, PA right now). #RStats #rayshader #skymodelr

Cipriano Hills, Organ Pipe Cactus NM (NE of Quitobaquito Springs). I hope you like this but I really just made it for my own nostalgic enjoyment. Data from @opentopography.org, visualized with #rayshader.

I dabbled with @thomasp85.com's {ggfx} package a bit this past weekend to generate a figure for an upcoming blog post and the result was pretty nice! I was able to add a subtle "atmosphere" that the data is representing to the background of the figure with a blurred gradient-fill rect. #RStats

Did this last week but never shared: a profile of Hunter Mountain's ski pistes. Should I do more? This was just a test of an idea. Might choose a mountain in Europe or Japan next time. #ggplot2 adventures, an #rstats tale

Ranking R function typing errors by the amount of whimsy they inspire: 1) libary: Ha, it's like I'm a toddler! 2) maen: Ha, it's like I'm Welsh! 3) liens: Ha, it's like I'm a banker! ... 1000) dplyr::fitler: 😶 #RStats

This was a fun quick experiment: Using an old photo I took in the forest, I used ml-sharp to generate gaussian splats from it, voxelized it in my toy renderer, relit the scene dramatically. #rendeting #metalrt

An "atmospheric" frame from an animation demonstrating the "Mahattanhenge" phenomenon in my upcoming blog post about rendering realistic atmospheres in R. #RStats #rayshader #rayrender #rayverse

Nine volcanoes of Japan. Mt. Fuji is instantly recognisable. The others too, I hope. This took a while to get right. Looks like fancy chocolates, no? Or little LED buttons. #rayshader adventures, an #rstats tale

Not sure what happened here but I like it! #rayshader adventures, an #rstats tale

Slow clap everybody: I rendered the 3D route animation with 16 instead of 32 samples per image in order to get it done in an afternoon rather than overnight. #rayshader #rstats

This is the most elite change in #Positron, it's so calming. #rstats #python #databs

Trying something different with Mount Snow in neon. Am of two minds about the light reflections...maybe microfacet is better. #rayshader adventures, an #rstats tale

This was supposed to be a draft render. Just a quick `render_highquality()` with no additional arguments. Is it me or does it already look pretty good? #rayshader adventures, an #rstats tale

Power lines of the United Kingdom. #rayshader adventures, an #rstats tale

Found the code to do this strange attractor while looking for something else. Thought I'd see how fast I can render 360 frames of this with denoising. What used to take hours now takes slightly more than 60 minutes. #rayrender adventures, an #rstats tale

Zootopia 2 took hundreds of artists, TDs, and engineers to make; I was lucky enough to be a small part of it all! Here are some of my personal thoughts/notes from working on Zootopia 2, along with some pretty pictures. blog.yiningkarlli.com/2025/12/zoot...

Smart choice not updating. I enjoyed reading this post; really got at the UX issues with Tahoe. What's worse: Tahoe broke XQuartz and I have to rgl_widget() as a workaround. 😠

Power lines of Germany revisited, this time showing both OSM and derived power lines. Should have done this from the start but was afraid it'd take too long to render this many lines. Guess not! :) #rayshader adventures, an #rstats tale

Mappy New Year! 🗺️ Kicking off 2026 with this triple polar vortex animation #Geospatial #GIS #GISChat #DataVisualization #Automation

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

This blog post on the proliferation of icons in macOS Tahoe makes the decision clear: I'm never updating to this cluttered mess. Where did your aesthetic taste go, Apple? Yuck. 🤮 Left: Macintosh Human Interface Guidelines Right: macOS Tahoe Read the post: tonsky.me/blog/tahoe-i...
