After nine years of development, meshoptimizer has reached its first major version, 1.0! This release focuses on improvements in clusterization and simplification as well as stabilization. Here's a release announcement with more details on past, present and future; please RT! meshoptimizer.org/v1

Funding: if your mid/large business uses Dear ImGui - and maybe you are approaching end of year budget/planning etc. - please consider reaching out (PM/email) so I can help you help Dear ImGui !

New blog post about the development of Radical Pie: terathon.com/blog/radical...

When I wrote PGA Illuminated, I had to paste an equation in Illustrator to draw highlights and annotations like these. Not any more. With Radical Pie, they get drawn directly in the equation editor, they auto-resize during edits, and everything stays live when embedding in Word.

Radical Pie has entered beta testing! I expect the final release to be available by the end of October.

TIL of VD-Dev, despite sharing past franchise titles with Guillaume Dubail and the late Fernando Velez. These guys were proper savants of their time, unlike those that tend to hit popular culture. I'm in complete awe of their work, Asterix & Obelix was mind-blowing. www.youtube.com/watch?v=rfOR...

The demo I’ve been working on is finally online: ludicon.com/sparkjs/gltf-demo/ It demonstrates the benefits of real-time texture compression in 3D web apps. It allows you to compare models using traditional KTX2 textures (UASTC and ETC1S) with the same assets compressed as AVIF + Spark.

Remembering MN house speaker Melissa Hortman, her husband Mark and their beloved dog Gilbert. Murdered in June at their home by a rightwing Trump-voting evangelist, who also shot another MN lawmaker and his wife at THEIR home, 9 and 8 times, respectively (miraculously, they survived).

Writeup by @icastano.bsky.social — very worthwhile comparisons for anyone building texture-heavy applications in WebGPU, with a case study and integration in @threejs.org!

New blog post about my experiences using spark.js with three.js: www.ludicon.com/castano/blog... Re-posts and feedback appreciated!

I am boycotting #SIGGRAPHAsia 2026 because it will be in Malaysia, where there are serious safety concerns for the LGBTQ+ members of our community, thereby excluding them. I will not attend, submit my work to, or perform any reviews for SIGGRAPH Asia 2026. Yet, I'm excited about #SIGGRAPHAsia 2025!

I’m excited to announce the release of Spark 1.3 and the launch of spark.js, our new JavaScript API for real-time GPU texture compression on the web. ludicon.com/sparkjs

Hi Vancouver!

Very big announcement from @icastano.bsky.social for WebGPU apps! Spark.js means you can send small file formats over the network (WebP, AVIF, ...) and compress to GPU texture formats like ETC2, BCn, or ASTC near-instantly using WebGPU — at runtime. #threejs #webgpu #webgl

I will be attending SIGGRAPH next week. Hit me up if you would like to meet and chat about Spark or anything texture related!

Wait, WHAT? BLASPHEMOUS 90% OFF? 🤯 ⚔️ Blasphemous is 90% off, Blasphemous II 50% off, and the bundle 68% off! Only until June 26! 🤭 store.steampowered.com/bundle/33529...

Gave up on trying to sell my Unreal Engine plugin, it's free now if you happen to want to 3D-paint textures in the Editor, or make things out of little grids-of-shapes: www.fab.com/listings/058...

I've been working on texture atlases recently. For dynamic atlases, I have liked the skyline packer as it's simple and effective. And growing the atlas texture up to certain point and then rebuilding everything has worked well as garba collection strategy.

Hands Off Protest in the Boston Common

Good call.

A slide about the death toll in Gaza “could be perceived as antisemitic.”

Epic Games CEO Tim Sweeney thinks the Tesla protests are being covertly funded by George Soros, Reid Hoffman, and Tesla competitors using shady proxy orgs they can't fathom that the backlash to this burning clownshow could be at all genuine

Deeply concerning news about our friend and former BF teammate Rebecca Burke whose backpacking trip to the US has ended with her being detained by ICE for over ten days, with no clear timeline for her release. Please read her father's statement here: www.facebook.com/paulrburke

I think it's pretty cool I can demo the codecs right on the spark website: https://ludicon.com/spark/ I could take this one step further and pre-load some images and demo specific features...

well this made me cry over breakfast. to any democrats holding even a shred of power right now: look at what’s possible from people far more endangered and vulnerable than you and grow a spine, you fucking cowards www.erininthemorning.com/p/powerful-s...

I’ve written a detailed blog post covering everything that’s new in Spark 1.2, check it out here: www.ludicon.com/castano/blog...

I'm excited to announce that Spark 1.2 is finally out! ludicon.com/spark/ This release brings major optimizations, new formats, and expanded platform support, solidifying Spark as the go-to solution for all your real-time GPU texture compression needs. What's new?

If you work at the Washington Post, now is the time to resign. You’re a part of this now.

I’ve updated the Spark demo app for Android to showcase the latest features coming in the next release! Check it out: https://play.google.com/store/apps/details?id=com.ludicon.demo_spark_android Let me know if you run into any issues!

I wrote about the journey to make GPU texture compression work everywhere, including some history on how I got into this field. Check it out! www.ludicon.com/castano/blog...

For the past few months, I've been quietly working on a new math typesetting application called Radical Pie. I've been talking about doing this for years, and now it's finally happening. Beta expected in a couple months. I'll be posting a lot more... radicalpie.com

I’m excited to see Spark is finally integrated in the HypeHype engine. It will be enabled in production tomorrow. So far everything has been working smoothly. Let’s hope it stays that way! bird.makeup/users/sebaal...

I'm very proud to announce that today NVIDIA has released our first public SDK for Neural Texture Compression (NTC)! github.com/NVIDIA-RTX/R... NTC exploits neural techniques to achieve 12-24x compression of PBR material textures with quality comparable or better than BC formats.

Around 35% of SpaceX’s revenue comes directly from the federal govt. Less than 1% of NPR’s budget comes from the federal govt.

Ya podéis disfrutar de esta carta de amor a Commandos y La Abadía del Crimen. Nacida en Teruel, y rematada a lo largo de toda la geografía española, el desarrollo más largo y ambicioso del estudio hasta la fecha ¡Que lo disfrutéis!

Pin this, save it, we’ll need it. “When a prison camp opens in your town…when a DREAMer is disappeared from your classroom…when the President destroys what’s left of the Constitution…They will all say they didn’t know this was coming. And I want the American people to know that they did.” AOC 🔥🎯

actually, wow, even slang doesn't _actually_ support this feature. turns out it will compile the code, but the emitted spir-v will just use the default value of the spec constant :( godbolt.org/z/9fqsGxxo6

“Specialization constants can be used in Vulkan to set the dimensions at pipeline creation time” From: bsky.app/profile/kost... Has anyone had any success with that? Last time I tried I run into all sort of compiler issues.

Our tech artist did a test scene with our forthcoming virtual texturing system. This scene uses just three 256x256 PBR materials (3 textures each). Total memory consumption (ASTC4x4/BC7) = 0.56MB Total storage cost (2bpp AVIF) = 144KB www.youtube.com/watch?v=IjlE...
