New blog post is finally up: (Ab)using Shader Execution Reordering. A bit of outside the box usage of SER (for better or worse). debaetsd.github.io/posts/ser/

My "No Graphics API" blog post is live! Please repost :) www.sebastianaaltonen.com/blog/no-grap... I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

So! Back in 2011, BitSquid made a "Header Hero" tool for C/C++ codebase header analysis. I did some updates to it in 2018. But now that I'm on Linux, I rewrote the UI (now it works on Win+Mac+Linux), did some performance improvements, and some other tweaks. Here: github.com/aras-p/header_hero

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

Two years of working on Blender Video Sequence Editor: aras-p.info/blog/2025/11... So far so good, let's continue! #blender #vse

Small blog post comparing binary sizes & performance of OpenEXR vs tinyexr libraries aras-p.info/blog/2025/11...

#gpc2025 was great! Met a lot of folks who I haven't seen in decades, or only know them from the internet, or haven't known them at all! I was a bit scared that after a decade out of rendering, everything would be way over my head, but turns out I could follow along just fine.

OpenEXR 3.4.4 is out, which reduced the size of the library binary by half a megabyte. This might have been my fault ;) github.com/AcademySoftw...

So! Blender Video Sequence Editor (VSE) has a roadmap/plan for 2026. Feedback or thoughts whether it makes sense would be welcome. Also more contributors would be good :) devtalk.blender.org/t/video-sequ... #blender #vse

"Oh no there's a Chocomel in my Playdate!" is back, but this time Chocomel is also on the web: aras-p.github.io/playdators/ and on github: github.com/aras-p/playd... #dogwalk #playdate

Suprise of the week: perhaps 15 people at Blender Conference said to me how they love Blender video sequencer (VSE) improvements. That is up from two or three people last year! “There’s dozens of us!” 😜 #blender #vse #bcon25

so proud to share @jhuapl.bsky.social neuroscience research at #blenderconference2025 @blender.org ❤️ also shoutout to #microscopynodes by @aafkegros.bsky.social, here's to awesome new collabs born at blendercon!!!

i put in a vectorscopey type thing into it, im sure subconsciously i was channeling @aras-p.bsky.social (have to edit #define TV to 1 in the shader)

i made a quick (silly) 'analog' scope www.shadertoy.com/view/wffBz8

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code. (And yes it's really been 10 years 👴). therealmjp.github.io/posts/ten-ye...

RenderDoc v1.40 is now available! This version includes support for VK_EXT_descriptor_buffer, and vulkan 1.4, as well as some other bug fixes an quality of life improvements. Full release notes: github.com/baldurk/rend... Binary builds: renderdoc.org/builds

"This many points is surely out of scope!", a blog post about moving #blender scopes to GPU, and point rendering performance in general. aras-p.info/blog/2025/08...

Anyone want to test #webgpu page where I'm testing performance of rendering many points, using GPU vs compute shader? aras-p.info/files/temp/w... I'd like to know GPU times for each of 5 buttons, with&without compute shader checkbox, and the GPU model. My own numbers at the bottom of the page.

If you're like me and can't remember if it's RCX or R8 for the fourth parameter... Get the Compiler Explorer ABI Mug: actual calling conventions for x86-64 System V, Windows, and ARM64. Support @godbolt.org: grab yours here -> shop.compiler-explorer.com/collections/...

= 32 bits after 32 years = We're incredibly proud to announce that Second Reality has now been finally ported to a modern operating system, and you can watch it tear up your system: no video, no emulation, just code - as it should be. conspiracy.hu/files/w32nd_... github.com/ConspiracyHu...

I finally saw Flow! it took about 3 minutes before I started crying and didn't really stop until 30 minutes after the movie ended but it was great <3

Blog post about lossless float image compression (EXR, HTJ2K, JPEG-XL, mesh optimizer): aras-p.info/blog/2025/07...

Small blog post about Blender Voronoi noise, hash functions and OpenShadingLanguage. aras-p.info/blog/2025/06... #blender #osl

Apple WWDC is happening, so: 20 years ago at WWDC Unity 1.0 has launched. I think it did have a massive effect of the whole game development! Also, 20 years in games tech is a really long time. #unity

While removing this 2000 lines of code, I learned that Blender has a "FELINE" texture sampling filter, which unfortunately has nothing to do with 😻 and just means "fast elliptical lines". Anyway, it is now gone since it was unused for years. projects.blender.org/blender/blen...

So to be landed PR: 6 lines added, 21581 lines removed. Buh-bye Collada, we hardly knew ye. projects.blender.org/blender/blen... (this is *not* counting the OpenCollada library itself, which is like 620 thousand lines of code lol).

I just published the bidi text stuff I have been working the past months. It's called Skribidi (because all text and font related things need funny name for some reason). github.com/memononen/Sk...

Reminder that if corporations are people, the reverse can also be true. You can just pretend to be a corporation, and do practical jokes like donate to #blender fund or something.

I wrote a blog post about mipmap level selection. pema.dev/2025/05/09/m...

The shelf packers is loosely based on @aras-p.bsky.social smol-atlas github.com/aras-p/smol-.... I think works pretty well. I have some ideas to improve it further, like it might make sense to truncate the empty rows/shelves too. Or have a shelf space allocator too.

I wrote a blog post about Blender, FBX, ufbx and similar pleasures of life: "Blender FBX importer via ufbx" aras-p.info/blog/2025/05... #blender

Maybe I should write a more proper blog post about FBX adventures, but here, a quick test of FBX parse times. ufbx is faster than the official FBX SDK by a factor of... 300? github.com/aras-p/test-...

I'm excited to share our latest paper (work with Matt Pharr and Tomas Akenine-Möller), "Improved Stochastic Texture Filtering Through Sample Reuse" accepted to I3D'2025. arxiv.org/abs/2504.05562 research.nvidia.com/labs/rtr/pub... 1/

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

Blenderheads ep 8 is ❤️: Sergey, including running Doom on an oscilloscope, and downloading images from space. Among other things. youtu.be/rcH_FStWob4

Oy! Are you importing FBX files into #blender? I have a new (WIP) FBX importer that would appreciate some testing. Blender forum thread: devtalk.blender.org/t/new-fbx-im... and PR with details: projects.blender.org/blender/blen... and builds to download: builder.blender.org/download/pat...

The world in 2025 is completely bonkers! For example, I went on a podcast! youtu.be/ioMKDonZcgg - at Wookash Podcast we talked about Unity, Blender and some other stuff. I’ve used up my talking quota for half a year.

Post you from a different era. 1997

This is pretty insane 😳😳

15y ago today I was just starting to work on Sintel, amazed by this "new way of lighting" by bouncing light off surfaces (!), mindblowing for any Blenderhead at the time. That was the addition of irradiance cache to Blender Internal, it never got merged but it sparked its replacement: Cycles 🧡 #b3d

We just had a short trip to the southern part of USA. New Orleans to Orlando. Here's a post with a bunch of pictures. aras-p.info/blog/2025/03...

I accidentally dithered. projects.blender.org/blender/blen...

A long-arse blog post about getting Surface-Stable Fractal Dithering effect running on Playdate, including several side quests. aras-p.info/blog/2025/02... #dithering #playdate

Alright, Surface-Stable Fractal Dithering by @runevision.bsky.social runs at about 20 FPS on Playdate now. Here's a video: www.youtube.com/watch?v=zhkA... and code at github.com/aras-p/playd...

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.

"The 3D Gaussian Splatting Adventure: Past, Present, Future" by George Drettakis is a great lecture. www.youtube.com/watch?v=DjOq...

Surface-Stable Fractal Dithering by @runevision.bsky.social is cool, but you know what's also cool? Running it on a Playdate, at way-too-slow-to-be-practical framerates :) github.com/aras-p/playd...

Unity Gaussian Splatting 1.1.0: now with Scaniverse SPZ format input support, and some Unity 6 URP render graph shenanigans. github.com/aras-p/Unity...

Tomorrow (Jan 22) a bunch of people are gonna talk stuff about gaussian splatting in an online mini-conference (register to get zoom link). metaverse-standards.org/event/gaussi...

Flow was made entirely with Blender and rendered in real time with EEVEE. We didn't use a renderfarm. The final render was done on my PC. There was no compositing, all the colors were tweaked and adjusted using shaders.
