Oh right, I remembered that I made Unity Gaussian Splatting eons ago. Well ok, a new maintenance release v1.1.2 is now out with a handful of fixes. github.com/aras-p/Unity... #unity #3dgs

"Unroll a loop, make shader 10x faster", where I accidentally speed up Blender's Kuwahara compositor node on Apple GPUs (and elsewhere). aras-p.info/blog/2026/10...

Turns out a little library I made for making #vulkan shaders smoller, "smol-v", is ten years old by now. Huh! github.com/aras-p/smol-v I just merged improved robustness against invalid data that someone contributed, & added more shaders to test data (from recent blender, godot, unity versions).

"GPU texture address mode collies" meme continues to be my main achievement in life, I think.

At #SIGGRAPH2026, I presented "points as tori" (PAT) for fast pointwise evaluation of signed distance for point clouds. Some code (Python w/ C++ extensions) and demo up: github.com/nzfeng/point... Contributions from people/LLMs welcome. Explainer thread below for the project: 🧵

I was told you couldn't do 3D on the Playdate, so I did it. Then I was told there was no way I could create exterior levels like those in Mirror's Edge, so I proved them wrong again.

We're finally bringing our powerful and user friendly CPU profiler to Linux! The beta version is now publically available, and it's free for 60 days during the open beta, so there's really no excuse not to try it out! Just download, extract, optimize. superluminal.eu/applications...

Posting this for a specific audience here.

You'd think that in Unity "how do I do a square root?" has a simple answer. It does not! Here's a blog post about various complexities of math related codegen, precision and performance in Unity: aras-p.info/blog/2026/06... #unity

📣🍏 Tiny Glade now runs on macOS! Mac users can finally pet the sheep (um, the rest of the game should work too 🤭) You'll need one of them "Apple silicon" Mac 'puters, like M1, M2, etc. or MacBook Neo. See our full post for details: store.steampowered.com/news/app/219...

Cheating as well, since this is fairly recent. My midlife crisis is this now.

Here’s a cool talk from GPC 2025 on the architecture of Blender’s Cycles renderer. There is no one right answer to designing a renderer; as a rendering engineer, I really like seeing how different renderers choose different tradeoffs to meet user needs: youtu.be/etGMk9wYwNs

'Syntonic Dentiforms' demo remake by @aras-p.bsky.social is using sokol for rendering and audio :) aras-p.info/blog/2026/04... Direct link to web version: aras-p.github.io/SyntonicDent...

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming. graphicrants.blogspot.com/2026/02/nani...

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...

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

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...

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

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...

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...
