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.
