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.

Actually drawing some ovals – that are not ellipses (2017) (medium.com)
In the last part I hopefully made it clear why you wouldn’t want to use an actual ellipse when making a real object, curves constructed from multiple fixed radius arcs are much more useful and look just the same.

When Gaussian Splatting Meets 19th Century 3D Images (shkspr.mobi)
Depending on which side of the English Channel / La Manche you sit on, photography was invented either by Englishman Henry Fox Talbot in 1835 or Frenchman Louis Daguerre in 1839.

The Early History of Deferred Shading and Lighting (sites.google.com)
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.

Mountains, Cliffs, and Caves: A Guide to Using Perlin Noise for Procedural Gen (jdhwilkins.com)
Procedural generation is everywhere—you’ve probably encountered it without even realising. It’s what gives in-game worlds their rolling hills, jagged cliffs, and winding cave systems. And at the heart of it all is Perlin noise: a special kind of randomness that isn’t entirely random at all. It’s smooth where it needs to be, rough when we want it to be, and endlessly customizable.

Animate Anyone 2: High-Fidelity Character Image Animation (humanaigc.github.io)
Recent character image animation methods based on diffusion models, such as Animate Anyone, have made significant progress in generating consistent and generalizable character animations. However, these approaches fail to produce reasonable associations between characters and their environments.

How Are Images Stored? A Deep Dive into GIF, PNG, and JPEG (cefboud.com)
This post is me indulging in a rabbit hole. I somehow found myself thinking about images, probably after my recent exploration of some compression schemes. It’s common knowledge that images are either grayscale or RGB, that mixing red, green, and blue creates new colors. But there’s certainly more to storing an image than just aligning three-byte RGB values.
