Exploring ways to mipmap alpha-tested textures
(lisyarus.github.io)
In my village building game I'm using alpha-tested transparency for foliage — trees, bushes, grass, etc. This works simply by discarding (i.e. not drawing) any pixels having an alpha value of less than 0.5, and keeping the others. This is much cheaper than proper transparency, which requires sorting objects or pixels by distance to camera.

Portals and Quake

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.

Modern Generic SVGA driver for Windows 3.1
(github.com/PluMGMK)
This is a rewrite of the Windows 3.1 SVGA driver, designed to support ALL available 8-bit, 16-bit, 24-bit or 32-bit graphic modes on any system providing the VESA BIOS Extensions (hence the VBE in the name). It is based on the Video 7 SVGA driver included in the Win16 Driver Development Kit, with most of the hardware-specific code gutted out, and with support added for multi-byte pixels.

X.org Server Development Hit a Decade High for the Number of Commits in 2024

To much surprise, the X.Org Server Git tree saw the most commits in 2024 going all the way back to 2014... While there were many more commits than in years prior, it's not a sign of resurgence for the X.Org Server with Wayland continuing to become the dominant force on the Linux desktop.

Parallel Vector Graphics Rasterization on the CPU
(gasiulis.name)
During the last couple of weeks I got some free time and as a fun programming exercise I decided to write a CPU-based, multithreaded vector graphics rasterizer. The goal was to outperform rasterizers of all publicly available vector graphics libraries. And today I’m sharing what I came up with.

How to Code a Shader Based Reveal Effect with React Three Fiber and GLSL

After coming across various types of image reveal effects on X created by some peers, I decided to give it a try and create my own. The idea was to practice R3F and shader techniques while making something that could be easily reused in other projects.
