meshoptimizer 0.24 is out! Featuring new meshlet builder for raytracing workloads, improvements to cluster partitioning, new functions for reindexing, simplification, clustering and coverage computation, many internal improvements and, of course, VS2013 support!

Thanks to Valve for sponsoring most of the work on the core library in this release!

Boost / GitHub stars appreciated as always :)

https://meshoptimizer.org has also been updated with better documentation structure, and more details where relevant. Hopefully that’s easier to navigate!

Fantastic news! We've reached 1 million votes! But please keep sharing and voting in case some votes are invalid!

EU citizens, please sign this petition to ban so-called "conversion therapy" in the EU. It's a practice that's extremely harmful towards LGBTQ+ people.

The site is a little slow, but keep trying!

It's already banned in some countries but we need a EU wide ban!

We now have eight countries past their thresholds, and we have at least 1,000,000 total votes.

So keep signing & voting!

“Mipmap selection in too much detail” https://pema.dev/2025/05/09/mipmaps-too-much-detail/

I wrote a blog post about Blender, FBX, ufbx and similar pleasures of life: "Blender FBX importer via ufbx" https://aras-p.info/blog/2025/05/08/Blender-FBX-importer-via-ufbx/ #blender :blender:

Mesa 25.1 got released today.

https://lists.freedesktop.org/archives/mesa-announce/2025-May/000802.html

This is big news for Nouveau users. Mesa 25.1 brings:

• Vulkan conformance for Maxwell, Pascal, and Volta GPUs (https://www.collabora.com/news-and-blog/news-and-events/nvk-enabled-for-maxwell,-pascal,-and-volta-gpus.html)
• Users with Turing and later GPUs will now get NVK+Zink by default for OpenGL instead of the old OpenGL driver. NVK+Zink is OpenGL 4.6 conformant, faster, and more stable than the old OpenGL driver. (https://www.collabora.com/news-and-blog/news-and-events/goodbye-nouveau-gl-hello-zink.html)

Happy gaming! 💜

New blog post! "Load store conflicts", in which we look at some performance sensitive code that has surprisingly dramatic performance swings based on the compiler and the microarchitecture used. Boosts appreciated!

About a month ago, I spent a few weeks fighting with ancient hardware and now Maxwell+ GPUs are all Vulkan 1.4 conformant with NVK:

As it says in the blog post, Kepler is on the way but no guarantees as to when that will happen.

Vulkan is ready! 🌋
...for testing.

I visited a lamp post on a bridge in tokyo that has been used as the center point for distance measurements for centuries. In the 1960s they built an expressway over it but made sure to suspend a replica of that lamp post over precisely the same spot. It’s a totally gratuitous shrine to infrastructure and I love it

In today's new blog post, I try to provide some intuition and clear up some misconceptions about early Z cull behavior on desktop GPUs. Have a read if that interests you!

Biggest commitment to a 3 second joke I've ever seen

New blog post! "Measuring acceleration structures", in which we will compare BVH costs on various GPU architectures and drivers and attempt to understand the details enough on AMD hardware to make sense of the numbers!

Boosts appreciated :)

meshoptimizer 0.23 is out! Featuring vertex codec v1 (increased compression ratio, faster decompression), even faster decompression on Apple Silicon, improvements to meshlet builder with fewer disconnected clusters and more options for clustered raytracing and hierarchical clusterization, new algorithms for hierarchical clusterization, simplification quality improvements and more.
