INTRODUCTION TO SPHERICAL HARMONICS FOR GRAPHICS PROGRAMMERS finally done. gpfault.net/posts/sph.html

Some particles experiment from ~a year ago

Heading to GDC next week as part of Apple’s GDC presentations on Wednesday!

New post! "Realtime Raytracing in Bevy 0.18 (Solari)" jms55.github.io/posts/2025-1...

Capsaicin is not just for tacos, it's also our developer rendering framework! v1.3 is out now: 🌶️ Added heat with GI-1.2, which includes multiple-bounce indirect lighting. 🌶️ HDR support with spicier tone mapping. And much, much more: gpuopen.com/learn/gi-1-2...

New blog post! Behind the scenes of some of the techniques involved in making our last PC demo 💫 gboisse.github.io/posts/this-i...

Get up to speed with our latest advanced graphics research: 📝 GATE (Geometry-Aware Trained Encoding) for neural rendering. 📝 Real-time procedural GPU tree generation. 📝 Neural Visibility Cache for real-time light sampling. 📥 Download the papers: gpuopen.com/learn/public...

Ticket booked, looking forward to it!

Been wanting to implement that fast GGX-based convolution for glossy reflections probes for quite a while and finally made some time for it:) research.activision.com/publications...

Most of the slides and course notes for the SIGGRAPH 2025 Physically Based Shading in Theory and practice course are now online, with more to follow: blog.selfshadow.com/publications...

💡 Do you want to learn more about using the matrix cores of AMD RDNA™ 4 architecture GPUs? Our quick how-to guide shows you how to: ✅ Use WMMA intrinsics on RDNA 4. ✅ Implement a simple MLP. 👉 Read the guide: gpuopen.com/learn/matrix...

Quick behind the scenes of our latest PC demo production, here’s the node graph for the part from 02:14 to 03:00: youtu.be/W7Om9rf0qKc?... Might print out more graphs from other scenes if there’s some interest:)

Perks of the job:) #rdna4

Radix Sort is a fast, non-comparison-based algorithm ideal for sorting large datasets especially on GPUs. 💡 Check out our research that introduces a memory-efficient GPU Radix Sort that improves on Onesweep: gpuopen.com/learn/boosti...

I had the great joy to present a new PC Demo "This is Us" at Revision 2025 demoparty, with the friendly members of Exist (Guillaume, BevelledApe, Quitt, Made)! Youtube capture: www.youtube.com/watch?v=W7Om... Music (free download): soundcloud.com/alkama/this-...

2nd place 🎉 thanks @revision-party.bsky.social!

Looking forward to tonight’s compos! @revision-party.bsky.social #demoscene

🚀 Today is AMD RDNA 4 day! To celebrate, we've got new content on GPUOpen: 🔥 Machine-readable ISA for RDNA 3.5/4 🔥 #opensource Interactive Streaming SDK 🔥 Updates to AMF + Capsaicin Find out more: gpuopen.com/learn/new_co...

🔥 Don't miss the reveal of the next gen AMD Radeon RX 9000 series, along with new technologies, on February 28th at 8am ET/7am CT/5am PT. 🎉 You can watch the unveiling LIVE on the AMD Gaming YouTube channel: bit.ly/3CRgfvX

Now drawn as a mesh 🎉

Testing the fluid sim. with object collision:)

To give a bit more detail on the SPH implementation, I build a tiled hash grid, where the hash points to a 4x4x4 tile (+ some linear probing for conflict handling).

Re-wrote my acceleration structure for neighbourhood search based on some insight from @vassvik.bsky.social and got significant speedups on large fluid simulations:) Here’s ~1/2 million particles ✨
