    I wrote my first blog post. I'm a bit scared to share it but that's what I made it for, so here goes.

    If you're one of the selected few, you can even look at a crude version that uses WebGPU here. Bugs and crashes expected ^^.

    Also, I've renamed my blog to The GutHub for obvious reasons.

    New blog post about exploring compute shaders performance and understanding GPU hardware. It was meant to be longer but I've been sitting on it for too long so I've decided to rebrand it to part 1 and to release it into the world🙃.

    Urgh, HR says "To be eligible, your application must comply with our interpretation of the French law. That is, it must be an integral part of your school curriculum and therefore a graduation course, and require the writing of an internship report assessed by your school."

    If you're looking for an internship and are interested in WebXR, search no more. Come prototype the future of AR experiences for with us in Paris. Sorry the description had to be in French, I'll happily translate if you're interested :). RTs appreciated!

    After a decade of WebGL bringing 3D graphics to the web and enabling all sorts of new experiences, it's now time to upgrade the stack and help web developers take full advantage of modern graphics cards. WebGPU arrives just in time! ~ Read 🚀

    Does anyone know if Blender exposes the "morph targets" you can find in some gltf assets? I'm thinking of the avatars you can create from Ready Player One for example. The GLTF viewer from exposes them and it's really cool!

    Apparently the "platform" buttons from VR controllers are not available anymore in WebXR when they were in WebVR. Is there any way old apps can still use them in order to not break control schemes when migrating? Do you have any insights ?

    RasterGrid has a few super interesting GPU articles. ( IMR vs tiled, memory types, GPU caches ) Highly recommended.

    Digital material interpolation is a simple yet powerful mechanism for creative design and data set amplification. MatMorpher runs in real time, at high resolution and preserves the mesostructure. See talk at EGSR 2021 today. Research paper & more:

    People who write performance-critical JavaScript and use Chrome DevTools: Would you like to get deoptimization and inline-cache-miss info directly in the profiler / source editor, with hints on how to fix it? Please RT and share with anyone you know who might have an opinion!

    People who generate shader permutations offline, how do you index them at runtime? Do you hash your runtime data to get the right shader? Do you do it every frame? What kind of hash function du you use? Tell me everything :).

    Better and faster! takes to the next level, providing a common abstraction over Vulkan, Metal and DirectX to leverage modern GPUs capabilities. 2D/3D rendering, general computing using the GPU (AI/ML, media processing, …) Soon in a nearby browser!

    JavaScript Twitter, am I missing something here? Why is there an Image Decode on ImageBitmap creation?

    I have a few days off coming. I'm looking for a cool short project, something like ray tracing in a weekend. Any suggestions? Bonus points if it involves my Quest 2.

    community: Safari on the iOS 14.5 betas contains the latest WebGL 2.0 code on top of ANGLE. Test it by enabling Settings > Safari > Advanced > Experimental Features > "WebGL 2.0". It's safe to browse the web with this. Please try, and file issues on WebKit's bug tracker!

    I'm thinking better cache behavior, less aliasing of reflections etc.
