May, 24 2025 • 16 min read • 2461 words 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). The Origins of General Purpose GPU Programming In the early 2000s, NVIDIA introduced programmable shaders with the GeForce 3 (2001) and GeForce FX (2003). Instead of being limited to predete

Background As a game developer who works primarily in frameworks instead of engines, one of the biggest pain points is the need to render on multiple platforms efficiently. For most platform-level tasks, like window management, input handling, etc, SDL does a beautiful job and I barely have to think about it. Rendering, by comparison, is a huge can of worms. Every platform has their own unique support matrix. For Windows you have D3D12/D3D11/Vulkan/OpenGL. For Apple platforms you have Metal an

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. XO by Nuance (4kB) In 2010, I noticed a trend in the demoscene: creators were producing impressive 4k intros, but the process was incredibly manual and tedious. These intros r

The Hellfire Gala isn't the only reason for Marvel Rivals PC players to party in Season 2. The hit hero shooter just got a new experimental performance setting that aims to speed up load times and prevent crashes. PC players have been plagued with issues since the release of Marvel Rivals. Even with adequate memory and beefy GPUs, the game's performance has been shaky for many players. The new mode aims to solve these issues, especially for any players who have 16GB of RAM or less installed in

In computer graphics, we rarely encounter continuous data. We often work with digital data, and in the context of geometric modeling, this means we typically work with polygon meshes rather than procedural surfaces like Bézier patches. The most popular technique for constructing digital three-dimensional objects in dedicated modeling software is polygon modeling. The result of the creation phase is a set of polygons (mesh), where the polygons in the mesh can share vertices and edges with other p

Edit: The article originally said Intel’s BVH nodes were 4-wide, based on a misreading of QuadLeaf. After inspecting Intel compiler code, QuadLeaf actually means two merged triangles with a shared side (a quadrilateral, not a quad of four triangles). Intel’s discrete GPU strategy has emphasized add-on features ever since Alchemist launched. Right from the start, Intel invested heavily in dedicated matrix multiplication units, raytracing accelerators, and hardware video codecs. Battlemage contin
