A black and white light map of the corresponding area of Canyonlands, though it doesn't look nearly as good as Tom Patterson's.

Ack, that's just so good. Been looking at his maps as I work on my increasingly-garbage-looking tiled shading technique, WIP article with viewer here: rreusser.github.io/notebooks/li...

Yes, so lush! Is this unusual? Trail through the forest was well marked, but I couldn’t stay upright on the ramp at the bottom of the hill, and the spiders were… large. I was surprised I really didn’t have to go far into the hills to have a real experience!

Looking over the forest from Yuanjue Temple. Dense green forest and valleys, clouds hang overhead.

Love following these adventures! Visiting and was inspired to get on a trail near Taipei for the first time this morning (near Yuanjue Falls). Once I left the main path, I could hardly stay on my feet it was so slippery, and after the tenth spider web, I gave up and played it safe! 😅

(Don't get me wrong though, not disagreeing, can't believe this all passed QA and accessibility testing. Just sentimental is all.)

These posts always make me sentimental for good old facebook groups where we'd all do our part by clicking join to protest drop shadows after the new iOS update or something. 🥲

Anyone have an e-reader they like? Amazon will stop supporting library books on my 16 year old Kindle, and I'd like a replacement for an upcoming trip. I hate that tech is disposable, but 16 years was a pretty good run. Main constraint is that I'll pay extra to avoid ad-supported awfulness.

Initial mat pattern. An orange climbing rope is laid out on yoga mats. It forms a loose pattern. Strips of paper label crossings.

The pattern now contains three passes of the rope. It is still loose.

The nearly-finished pattern sits on a wood floor. It contains five passes. A strand extends from the corner, indicating its creator still feels non-committal about calling it finished.

Retiring a climbing rope and didn’t want to throw it out. Didn’t like the first attempt so redid with a more interesting pattern. The initial pattern was the hard part, feeding rope into it (still needs adjustment) is the tedious part.

My hands are raw from pulling rope through this thing for a few hours, but I'm so temped to undo it all and upgrade to a pattern with five-fold symmetry.

The beginning stage of an ocean plait mat made out of used orange climbing rope is laid out on a yoga mat. A rabbit sniffs cautiously at it.

A small white dog now sits at the edge of the yoga mat, looking with uncertainty down and to the right. The plait mat now has about eight or nine passes completed, with quite a bit of loose rope to be pulled through yet.

The (nearly) finished ocean plait mat sits on the yoga mat. It is pulled tight, with no gaps in the pattern. Two loose strands dangle from it, not yet cut off.

Significantly more work than I expected, tbh. Tempted to loosen up the pattern and give it some breathing room—but it's just so much work to feed all the rope through to adjust the pattern.

One of my professors used to have a downwards-pointing clip art space shuttle printed out and posted on his door with the caption, “But it’s only a sign error!”

On the flip side, it makes AI-written code hard to maintain without AI. And yes, on average. I definitely have seen a strong tendency toward this sort of code in a couple places I could name, and which predated AI by a while.

Got a $25 Peet’s gift card as a result of one of those data breaches, and I’m feeling, basically, just really good about croissants right now.

Also apparently seems very highly trained on frequently-photographed locations.

Although, as I contemplate this, I guess one ought to be very careful in how they use this, as depictions of real places could easily be misinterpreted as an actual representation of that place.

Fixed the other issue, I was setting (x,y,z,w) = (0,0,0,0), which is invalid on some GPUs and causes the triangle to get culled, on other GPUs is the origin.

As for the text… I think I didn't handle non-retina displays correctly. Not sure about the rest of the artifacts!

Elevations are encoded as images. Brave adds noise when decoding images, for fingerprinting prevention. So if Brave wants randomness, Brave gets randomness!

Denali Terrain Interactive 3D terrain viewer for the Denali region built from scratch with WebGPU

Will it crash your browser? Maybe! But you can test out the (WIP) viewer here (WebGPU required): rreusser.github.io/notebooks/de... 🏔️

Somewhat happy with progress on my crappy ad hoc map renderer. Labels are hard.

ArcticDEM – Polar Geospatial Center

Nice! Bookmarked. I got my data from here: www.pgc.umn.edu/data/arcticd...

A low-angle view of Denali, looking up the northeast fork of the Kahiltna Glacier. The view is computer generated with basic hillshading and a flat blue sky.

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.

My fullerene simulator for designing toilet paper tube constructions is still one of my favorites. Try it in its new home as an @observablehq.com Notebook Kit notebook! 🧻🧻🧻 rreusser.github.io/notebooks/ch...

Visualizing Sloan Digital Sky Survey Data Visualizing 3.3 million galaxies and quasars from the Sloan Digital Sky Survey

Threw WebGPU at some data from Sloan Digital Sky Survey. No real content here, but gosh it's satisfying to visualize. (Hope I didn't get any details wrong!) rreusser.github.io/notebooks/vi...
