meshoptimizer 1.3 is out! Featuring a new voxel remesher, support for normal generation, several simplification improvements and various optimizations and fixes. GitHub stars and reposts appreciated! meshoptimizer was started 10 years ago; excited for the years to come! github.com/zeux/meshopt...

New blog post! In "Billions of triangles redux" we take another stab at improving various parts of clustered level of detail pipeline to make Zorah smaller and nicer! zeux.io/2026/09/30/b...

DASHR - Dynamically Animated Skinned Heightfield Rendering Short video for now - I might do a longer one later? youtu.be/-Su9YrcazRk But there's ALL the details in the paper, and you can always Use The Source, Luke for the really deep info. github.com/tomforsyth10...

one more thing before I unplug for a couple weeks: nicer vertex normals!

meshoptimizer 1.2 is out! Featuring support for tangent generation, a significantly faster vertex decoder for Intel/AMD CPUs, several new smaller algorithms (cluster position compression, triangle filtering, clusterlod BVH) and more. GitHub stars and boosts appreciated! github.com/zeux/meshopt...

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...

New blog post! In "Zigzag decoding with AVX-512", we look at two different ways to possibly (caveat emptor) speed up various forms of zigzag decoding with AVX-512 functionality that isn't just "wider registers"! zeux.io/2026/06/17/z...

pugixml 1.16 is out! It's a nice release, but also it's the 20th anniversary release, so I wrote a few words on the history in the release notes :) but also it's a well rounded release by itself, with bug fixes, performance improvements and a couple tiny features. github.com/zeux/pugixml...

Spent some time yesterday working with a few different scenes and doing a few performance tweaks. Commits should be self explanatory, so just sharing for anyone curious :) github.com/zeux/niagara...

A list of experimental meshoptimizer APIs. When 1.0 was released in December last year, the only experimental API was marked with the green checkmark.

Almost 10% speedup on this view from an upcoming meshopt function (1.05 => 0.96ms). Obvious omission in hindsight...

who even needs triangles in the first place

While volk always tracks the latest Vulkan version (I've automated myself), I occasionally tag new numbered versions and today is such a day! New release 1.4.350 features a number of small improvements for various edge cases as long as all the new extensions you may want. github.com/zeux/volk/re...

New blog post! In "Quantizing tangent frames", we look at various established methods to represent tangent frames in the vertex data, squeeze a few variants into 32 bits per vertex and look at the resulting precision. zeux.io/2026/04/30/q... Share, like and subscribe!

If you’re in SF the week of GDC and would like to get coffee and chat about game technology, email me! I probably won’t be at GDC proper but will be around.

Yesterday on stream we've sketched out most of the support code for descriptor heaps. If you want to see the rest of the owl, I've committed the remaining pieces after the stream. For now all of the previous descriptor code is still required to support production drivers. github.com/zeux/niagara...

Still some bits to sand off but getting closer.

The fact that the entire industry is now wasting time working on, integrating, analyzing, reviewing, and commenting on frame generation is so sad. Surely there are actually productive things we all can be doing instead.

Upcoming niagara stream! Tomorrow (Sunday, Dec 21) at 11 AM PST (7 PM GMT), we will work on reducing the startup time by "cooking" the geometry and, if that gets done quickly enough, optimizing texture loading. www.youtube.com/live/d04h0sZ...

One fun feature that meshoptimizer got in the last two years that I forgot to mention in my v1 post is support for provoking vertex optimization for primitive ID rendering. Implementation is based on exploration by John Hable (thanks!) and is used by Wicked Engine meshoptimizer.org#visibility-b...

Tomorrow comes.

Half resolution is when you cut width and height in half, and get at best half of your rendering time back, since rarely if ever do things scale perfectly with pixel count.

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

Do I know anyone in Poland who will be there next week and wants to get tea or whatever people drink there and chat? Schedule not too flexible but I might be in the right city at the right time :) DM me!

Is anyone still using DirectXMesh library? If so, why?

New blog post! In "Billions of triangles in minutes" we'll walk through hierarchical cluster level of detail generation of, well, billions of triangles in minutes. Reposts welcome! zeux.io/2025/09/30/b...
