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.

Was going through my video archives looking for something and laughed at this, thought I'd let Bluesky enjoy #RStats #rayshader

#30DayMapChallenge · Day 22 · Natural Earth. Many spinning globes. Honestly, I don't know how to use this amazing resource because I'm—no surprises here—not a cartographer. Am just a one-note guy who likes R.

I was there from almost the beginning. Behold my ggplot sword from 2019! This took hours to render back then.

Do you know it's been almost seven years since I released #rayrender, ranked for 6 years straight as the #1* pathtracer in #RStats? I went back to a blog post (www.tylermw.com/posts/rayver...) I wrote over six years and recreated some of the scenes, and it's fun seeing how far it's come!

#30DayMapChallenge · Day 21 · Icons. Lighthouses of the Pacific. Yes...I've done lots of lighthouse maps but not in this projection. I still like it—there's nothing like path-traced points of light realistically rendered.

Here's a great video explaining/showing why the common CG practice of plugging smudge/fingerprints/dirt/whatever maps into roughness is wrong and why it should be done using material layering instead. This video is really well-made!

I’m so happy this is how I found out a new Stargate series has been greenlit, and it’s not a reboot!

I am a day or two behind now. I finally got #Rayshader installed; it was a whole ordeal. This map is nothing crazy. Just a hillshade of Rhode Island that I annotated in #AffinityDesigner.

I found another variant of Perozzo's stereogram, from 1881. Here it is (!) above my Gabaglio 1888 and Brinton 1939. Its colors are beautiful.

One thing I appreciate about {targets} is the robustness of the pipeline: if I need to stop a long, compute-intensive process to run something else (or, in this case, I resize a pane and make the IDE crash🤷♂️), I don't need to worry about corrupted state: just restart R and tar_make() away!

‼️ #rayverse package update: #rayvertex v0.14.0 released! This overhauls the toon shading algorithm to use a screen space jump fill algorithm (JFA), removing the brittle inverse mesh hack that existed up until now.
