Image Dithering: Eleven Algorithms and Source Code
(tannerhelland.com)
Today’s graphics programming topic - dithering - is one I receive a lot of emails about, which some may find surprising.

The Early History of Deferred Shading and Lighting

At the 2004 Game Developer Conference Matt Pritchard (one of my coworkers at the now closed Ensemble Studios who wrote Age of Empires 2's graphics code), John Brooks (CTO and my boss at Blue Shift Inc., the graphics programmer on "Super Mario Wacky Worlds") and I came out of the cold and gave a fairly rushed, but groundbreaking 1 hour presentation on real-time deferred rendering techniques to an audience of 300-400 people.

OpenGL to WASM, learning from my mistakes
(uds5501.github.io)
The last few weeks, OpenGL has caught my eye (frankly, it was a hiring challenge that nerd sniped me). I had 0 experience with OpenGL whatsover and thought that this might be a good time to give graphics a shot! If nothing I’ll at least revise the graphics concepts that I’ve long forgotten after my 6th Semester.

Dissecting "Tiny Clouds" shadertoy (2017)
(demofox.org)
There is an amazing shadertoy called “Tiny Clouds” by stubbe (twitter: @Stubbesaurus) which flies you through nearly photorealistic clouds in only 10 lines of code / 280 characters (2 old sized tweets or 1 new larger sized tweet).

C Compiler to SPIR-V
(github.com/heroseh)
HCC is a C compiler that allows you to compile your C codebase (with limitations) to SPIR-V for the Vulkan graphics API. This means you can share struct's, enum's and functions between your CPU & GPU code. HCC targets the future of GPU programming so is designed around features such as bindless resources and scalar alignment. This makes it easier to interop with the GPU and focus on writing shader code without writing your own shader build system.

Texture-Less Text Rendering
(poniesandlight.co.uk)
Sometimes, all you want is to quickly print some text into a Renderpass. But traditionally, drawing text requires you first to render all possible glyphs of a font into an atlas, to bind this atlas as a texture, and then to render glyphs one by one by drawing triangles on screen, with every triangle picking the correct glyph from the font atlas texture.

The best darn grid shader yet (2023)
(medium.com)
For as long as I’ve been writing shaders, there’s been one specific shader I’ve always tried to write. And I’ve always failed at it for reason I could never fully understand. I’d wait a few years and try again with my new level of knowledge, get closer, and fail again. That goal?

Writing Portable Rendering Code with Nvrhi

Modern graphics APIs, such as Direct3D 12 and Vulkan, are designed to provide relatively low-level access to the GPU and eliminate the GPU driver overhead associated with API translation.

DirectX Adopting SPIR-V as the Interchange Format of the Future
(microsoft.com)
Today the Direct3D and HLSL teams are excited to share some insight into the next big step for GPU programmability. Once Shader Model 7 is released, DirectX 12 will accept shaders compiled to SPIR-V™.

GPU Debug Scopes

Rendering APIs these days tend to capture their gpu workloads into a serialized form such as a command-buffer or command-list to be dispatched at a later time into a work-queue.
