Bilinear interpolation on a quadrilateral using Barycentric coordinates A new algebraic method for hardware-accelerated bilinear interpolation on convex quadrilaterals is presented, using the Barycentric coordinate feature of modern GPUs.

🔼 Triangles may have won the hardware-acceleration rendering battle ... 🔼

⏹️ ... but the method in our latest blog enables emulation of quadrilateral rasterization, through bilinear interpolation of quadrilateral vertices! ⏹️

I read it and used it and, indeed, it is a very interesting article.

Dynamic Register Allocation on AMD's RDNA 4 GPU Architecture Modern GPUs often make a difficult tradeoff between occupancy (active thread count) and register count available to each thread.

Hello you fine Internet folks,

Today we are continuing our deep-diving into the RDNA4 architecture with looking at the newly added Dynamic Register Allocation and how it compares to Nvidia's `setmaxnreg`.

Hope y'all enjoy!

I use Slang since I joined NVIDIA and the transition from HLSL/GLSL was trivial. Then, I discovered all the cool new features, and helped differentiable Slang.
We wrote an article on example use-cases for backpropagation for games, coming out soon in GPU Zen 3! gpuzen.blogspot.com/2024/11/gpu-...

(Yet another) Introduction to quaternions

✨A new article: (Yet another) Introduction to quaternions!

I'm a mathematician, so my desires are unconventional and my perspective is skewed, but I hope it will be useful at least in some way 😅

I've also added a useful cheatsheet in the end 🥳
