Hi all! A (re)-introduction: I'm Tyler, developer of #rayshader and the #rayverse, a collection of R packages for 3D #dataviz and #mapping.
Here's one of my greatest hits (now that Bluesky supports videos!): The Earth's submarine fiber optic cable network, visualized in #RStats with #rayrender.

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

Trying something different with Mount Snow in neon.
Am of two minds about the light reflections...maybe microfacet is better.

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?

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.

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.

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! :)

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.

heads up that bluesky doesnt show posts from other languages by default on your timeline, and its cutting you off from a lot of the community
go to bsky.app/settings/lan... and deselect any language from this setting, or else you might not see any of the new japanese users at all!

If this same thing is ever an issue for someone on a Mac just shake the cursor real fast and it'll magnify it so you can find it. I use this constantly bc I have two monitors and also way too much on them.
For the past few years, I have occasionally have had trouble finding the mouse pointer on my monitor. I just chalked it up to getting older ("I guess it's all downhill from here!"). But recently, I found a feature in Windows that draws a circle around the mouse when you hit CTRL...
