An Introduction to Practical 3D Math for Programmers (stunlock.gg)
There are a lot of guides for 3D math that seem to be written by people quite good at math. If instead you're like me and better at programming than math this is the guide I wish I had when I first started learning OpenGL, Direct3D, Shaders, Unity, and Unreal.

Derivatives and Logarithms of 3D Transforms (nosferalatu.com)
Given a transform \(T\) and a point x, we can find the transformed point with \(T * x\). But what if we want to smoothly interpolate \(T\) so it moves \(x\) along the path from its initial position to its position transformed by \(T\)?

Robust Wavefront OBJ model parsing in C (nullprogram.com)
Wavefront OBJ is a line-oriented, text format for 3D geometry. It’s widely supported by modeling software, easy to parse, and trivial to emit, much like Netpbm for 2D image data. Poke around hobby 3D graphics projects and you’re likely to find a bespoke OBJ parser. While typically only loading their own model data, so robustness doesn’t much matter, they usually have hard limitations and don’t stand up to fuzz testing.

Rediscovering Quaternions (jasonfantl.com)
How do we represent a rotation in 3 dimensions? This is a surprisingly deep question, and one we can learn a lot from. Our goal will be to “rediscover” quaternions from first principles, building them up by exploring different representations and fixing the failures along the way.

Portals and Quake (30fps.net)
Ever wanted to know how exactly did Quake’s precomputed visibility work? I did, so I wrote vis.py, a reimplementation of their algorithm in Python. This guide has all the information you need to understand vis, the tool used by Quake, Half-Life and Source Engine games.

Show HN: I've made a Monte-Carlo raytracer for glTF scenes in WebGPU (github.com/lisyarus)
This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API. It expects a single glTF scene as input. It supports flat-colored and textured materials with albedo, normal, and material maps. It doesn't support refraction (yet).

Lou's Pseudo 3D Page (2013) (extentofthejam.com)
Now that every system can produce graphics consisting of a zillion polygons on the fly, why would you want to do a road the old way? Aren't polygons the exact same thing, only better? Well, no. It's true that polygons lead to less distortion, but it is the warping in these old engines that give the surreal, exhillerating sense of speed found in many pre-polygon games.

Classic 3D videogame shadow techniques (30fps.net)
Towards the end of Wim Wenders’s excellent Perfect Days, the protagonist Hirayama is drinking beer under a bridge after he has seen a Businessman courting his crush. Suddenly the Businessman joins him under the bridge. As it turns out, things aren’t actually that simple but the point is their conversation takes them to some fundamental questions:

Image Editing with Gaussian Splatting (unite.ai)
A new collaboration between researchers in Poland and the UK proposes the prospect of using Gaussian Splatting to edit images, by temporarily interpreting a selected part of the image into 3D space, allowing the user to modify and manipulate the 3D representation of the image, and then applying the transformation.
