This feedback loop of textures is a mode of general purpose GPU computation. We can configure WebGL to do plain old math for us!
But why would we do this— send our homework to the video card, just to crunch some numbers and send them back? Well, some math is very GPU friendly. But also, some math is ONLY used to produce graphics. So we might as well get it all done in one place.
Surprise surprise, my Matrix demo computes the entire effect on the GPU. It's just a picture that redraws itself. 🔄
So, let's say you want to apply special effects to your graphics, like a badass green glow. Like most digital graphics techniques, special effects boil down to doing math on pixels. And if you want your special effects to look good, you need your pixels to store precise information.
By default, a pixel in a WebGL texture is just four bytes— one byte per channel of RGBA. That's a non-starter.
But WebGL has optional extensions for textures that are four single or half precision floats per pixel!
WebGL is not only verbose, it's also designed the way people thought graphics ought to be drawn twenty years ago; using it is hard! So most people who make 3D web content build on top of a library, like ThreeJS. I did! Zero shame in it, it's perfectly sensible to slingshot your project past the "wtf is gltexsubimage2d" phase of 3D web graphics, and into the cool zone.
For instance, my Matrix demo was originally a ThreeJS project. But as we'll soon see, it's changed quite a bit, and so have I 😁
All right, folks, how about I follow through on what I said a month ago, and post something about #WebGL?

For those who aren't familiar with Verreciel (as in "verre de ciel", which is Montréalais for "sky glass"), it's a minimalist space exploration game, where you kind of sit in a wireframe cockpit, fly to wireframe worlds and accomplish wireframe missions. It contains a music album by Aliceffekt!
Speaking of rainbow shapes, check this out! 🌈🔬
Nerilso G. Bocchi and Romeu C. Rocha-Filho, at the Federal University of São Carlos, have translated my reproduction of J. F. Hyde's spiraling Periodic Table into Portuguese, and made it into a
to celebrate the 150th anniversary of Mendeleev's table. 🍾
And they did a super good job too! One of them has got SERIOUS vector graphics chops. It was probably a pain in the butt to do! I'm super impressed.
You've probably already seen it, but I made some progress on my personal site.
Feedback is welcome! 😃
I finally put that 3D logo gizmo together, and get this: you can click it, and it goes through modes. 😊 I'll add more or swap them out from time to time.
There's also a basic Beliefs page and a stubbed Links page. They'll be built like the webring's other sites, lots of little snippets indexed for easy perusal.
( @neauoire may I join the webring? 🙏 )
Part of uploading my new site to my webspace involves picking through the detritus I've uploaded over the years. Like BitmapEditor, my early Flash playground for developing brushlike art tools. The motley brush, for example, was only ever really good at producing blurry technicolor swishy shapes.
I spent way too long overthinking BitmapEditor.
It costs next to nothing to do the digital equivalent of hoarding, but who would truly miss BitmapEditor if I deleted it for good?
It’s official, folks! We’re married! 🤩 This is our traditional Jewish marriage contract; the wreath is composed from illustrations are from an artist on Etsy who I’ll look up and credit later 😅
Last week I got stressed and made an audio visualizer to chill out.
Does anyone here have Creative Commons licensed music I could select from? It’s not a contest, because you’re all talented and contests exploit people. But ideally I’d like whatever music I use to come from the Merveilles community. 😊
Here’s a video of the visualizer in action. It’s WebGL, source is free online at https://www.github.com/Rezmason/modicum
A sixty-five-year-old employee of the Tokyo subway is making handsome signage from duct tape:
I've added new art to Fuligo! Icons, and a patterned theme!
Why, you ask?
So colorblind people can play, of course! I'll add other sorts of accessibility later.
Also, because the classic 1991 game used patterns the same way, to support black and white Macs.
Also also, the patterns I chose are classic Japanese motifs, so they pair well with the icons, which are inspired by Japanese family crests.

Prepare to be underwhelmed!
So, for the past three or four years I've had a ditty stuck in my head, that usually pops into my mind when I'm in the shower, instead of the usual Nobel prize winning ideas other people get.
I shoved it into Garageband earlier this week, and it's a mess. But I think there's something in it that I could build on.
There's lyrics, but I think it'd be easier to operate on feedback without including that stuff 😁
