Modern rendering culling techniques🌲 The best work is the work that never gets executed April 16, 2026 · 16 min read Saints Row: The Third Remastered - my first shipped title. Steelport is a dense open-world city, but the game also has tight indoor corridors, jets, cars, and parachute sequences. Getting culling right across all of that was a real challenge. Shoutout to Timur Gagiev - absolute leg
ASCII characters are not pixels: a deep dive into ASCII rendering Recently, I’ve been spending my time building an image-to-ASCII renderer. Below is the result — try dragging it around, the demo is interactive! One thing I spent a lot of effort on is getting edges looking sharp. Take a look at this rotating cube example: Try opening the “split” view. Notice how well the characters follow the conto
Opening this PNG in Chrome shows a different image than in Safari or any desktop app Check this beautiful painting, Pleading, an artwork by Sir Lawrence Alma-Tadema: If you are using Firefox or a Chromium browser (for me Google Chrome 143.0.7499.170), it's very likely that you are seeing a very foggy version of the painting, however, if you download the image and open it with your default image vi

いきなりですが、2つ質問です。今まさにあなたが読んでいる文字がどうやってレンダリングされているか説明できますか？私はできませんでした。それではあるモノの仕組みを理解するために最も効率の良い方法は何でしょうか？そう、自作することです！それではフォントのパーサーとレンダラーをゼロから作っていきましょう！ 目的 小さなTrueTypeレンダラーを自作し、フォントがレンダリングされるまで流れを理解することが目的です。具体的には、Unicodeのフォントを読み込んで、任意の文字列をレンダリングしpngファイルとして書き出すまでを目標とします。実装はほぼプレーンなC++で、ベクトル演算用にglm、png書き出し用にstb_image_writeを使います。コード全体は以下から確認できます。 TrueTypeとは TrueTypeとはAppleが1990年に開発したフォントのフォーマットです。その後Mi
#Introduction Apple introduced the Liquid Glass effect during WWDC 2025 in June—a stunning UI effect that makes interface elements appear to be made of curved, refractive glass. This article is a hands‑on exploration of how to recreate a similar effect on the web using CSS, SVG displacement maps, and physics-based refraction calculations. Instead of chasing pixel‑perfect parity, we’ll approximate
Blurs are the basic building block for many video game post-processing effects and essential for sleek and modern GUIs. Video game Depth of Field and Bloom or frosted panels in modern user interfaces - used subtly or obviously - they’re everywhere. Even your browser can do it, just tap this sentence! Effect of "Bloom", one of many use-cases for blur algorithmsConceptually, “Make thing go blurry” i
Physically based rendering from first principles In this interactive article, we will explore the physical phenomena that create light and the fundamental laws governing its interaction with matter. We will learn how our human eyes capture light and how our brains interpret it as visual information. We will then model approximations of these physical interactions and learn how to create physically
This animation of Rick was made with 240 lines of code. No libraries, no images. I’m going to show you how to use GPU shaders and signed distance fields to make animations like it for videos, video games, or just for fun! I even built a live coding editor into the page so you can see the examples running and tinker with them. vec2 rotateAt(vec2 p, float angle, vec2 origin) { float s = sin(angle),
This is an introduction to a series on creating psychedelic-looking visuals, especially for animation and games. It assumes no prior knowledge to working with graphics nor programming, although having exposure to trigonometry and programming will help. By the end, I hope you will have some understanding of the basics of the psychedelic graphics that I put in my videos. While the majority of those
Look at these two consoles: Side-by-side comparison of the NetBSD console right after boot vs. the EndBASIC console.Same colors, (almost) same font, same… everything? Other than for the actual text they display, they look identical, don’t they? But the one on the right can do things that the one on the left cannot. Witness this: A square? OK, meh, we had those in the DOS days with box-drawing char
Introduction Fidget is a library for representing, compiling, and evaluating large-scale math expressions, i.e. hundreds or thousands of arithmetic clauses. It's mainly designed as a backend for implicit surfaces, but the library is flexible enough for many different uses! Try the demo What are implicit surfaces? Implicit surfaces are expressions of the form $f(x, y, z) \rightarrow d$ returning a
