Freshwater ecoregions of South America.
But why didn't you do this in #rayshader?! Of course I did, but am still sorting out a few issues because rivers don't fall neatly into categories...

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.

Back to ski runs. I liked @infowetrust.com's suggestion and got to work but was frustrated by label size and placement.
So I made it interactive, two ways. Which do you prefer?

Visualising ski run elevation profiles of Hunter Mountain.
Thoughts? I tried facetting them by difficulty but they'd look either too wide or tall. Is it useful, interesting? Might be worth combining with an isometric view (in rayshader).

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?

That's it. I have had enough of `rgl::rglwidget()`.
Time to revert to Sequoia.

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.

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! :)

Ships of the Gulf of México. Thought I'd try to overlay all of them on one viz this time. Probably clearer if I split them up, no?

I can now paint with #rayshader. This is with a mere ten samples.

This lo-res, firefly-ridden render of Brasil's power transmission lines (osm and derived) took hours. Turns out even with Tyler's amazing optimizations, I can still bring the rendering process to a crawl. To be fair, it's over 150k lines.
