Running GPT-2 in WebGL: Rediscovering the Lost Art of GPU Shader Programming (nathan.rs)
Preface: A few weeks back, I implemented GPT-2 using WebGL and shaders (Github Repo) which made the front page of Hacker News (discussion). By popular demand, here is a short write-up over the main ideas behind GPU shader programming (for general-purpose computing).

Particle Life simulation in browser using WebGPU (lisyarus.github.io)
You might know that I'm a sucker for physics simulations, and particle simulations in particular. Usually I implement something based on conventional physics, but recently I've stumbled upon a funny non-physical model that can display...well, let's call it life-like behavior.

Traditional and Neural Order-Independent Transparency (tobias-franke.eu)
Order independent transparency (OIT) is a technique in computer graphics that allows for accurate rendering of transparent objects without the need to sort them in a specific order based on their depth.

Precomputing Transparency Order in 3D (jacobdoescode.com)
Transparency — or more precisely, translucency — remains a problem when rendering in 3D. When you have translucent shapes, the order in which they get rendered is very important. Consider what happens if this is done incorrectly.

Mipmap selection in too much detail (pema.dev)
In this post, I want to shed some light on something I’ve been wondering about for a while: How exactly are mipmap levels selected when sampling textures on the GPU?

15 Years of Shader Minification (ctrl-alt-test.fr)
How do demosceners create complex computer animations in just a few kilobytes? One of our secret weapons is Shader Minifier, a tool that minifies GLSL code. Over the years, it has evolved to pack more data into tiny executables, pushing the boundaries of what’s possible. In this blog post, we’ll go through its evolution.

Building a Fast, SIMD/GPU-Friendly Random Number Generator for Fun and Profit (vectrx.substack.com)
When writing shaders, SIMD code, or GPU kernels, one typically doesn’t need a cryptographically secure random number generator — something fast and statistically decent is often good enough.

Monte Carlo Crash Course: Rendering (thenumb.at)
So far, we’ve explored Monte Carlo methods using simple examples, like sampling the unit disk and sphere. Now, we’ll apply Monte Carlo to a more realistic task: simulating light traveling through a scene, or rendering.

Procedural Textures with Hash Functions (douglasorr.github.io)
I'm the sort of person who gets very excited when simple rules create complex behaviour. The other day, I needed a simple hash function that maps $(x, y)$ coordinates to a colour, and found a straightforward equation that ended up being astoundingly rich. Hence this post; to talk about and play with this function.

Measuring Acceleration Structures (zeux.io)
Hardware accelerated raytracing, as supported by DirectX 12 and Vulkan, relies on an abstract data structure that stores scene geometry, known as “acceleration structure” and often referred to as “BVH” or “BLAS”. Unlike geometry representation for rasterization, rendering engines can not customize the data layout; unlike texture formats, the layout is not standardized across vendors.
