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.

GraphicsMagick needs some additional productive volunteers (graphicsmagick.org)
GraphicsMagick needs some additional productive volunteers. For several years now, the burden has entirely been on me (Bob Friesenhahn). I have been sheparding the project for 23 years already (and contributed to ImageMagick and GraphicsMagick combined for 29 years already). Volunteers are needed to add/improve new/existing file format support, and to assure correct operation on all targets.

Surface-Stable Fractal Dither on Playdate (aras-p.info)
Rune Skovbo Johansen has a really sweet Surface-Stable Fractal Dithering technique, where the dither dots “stick” to 3D surfaces, yet the dot density adapts to the view distance and zoom level.

Show HN: 1M+ animated GPU sprites in JavaScript (phaser.io)
Based purely on the title this may sound like another beta of Phaser v4, but under the hood this is a truly exciting release! Yes, Beta 5 mostly focuses on fixing issues that surfaced in Beta 4, but it also introduces the final piece of the Phaser Beam jigsaw: The brand new Sprite GPU Layer Game Object.

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 (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.

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.
