Slughorn, MIT-licensed GPU-agnostic Slug font/glyph rendering library for OpenGL/OSG/Vulkan and all GPU-driven graphics APIs
Slughorn: Applying Slug-Style GPU Curve Rendering Beyond Text On March 17th 2026, Eric Lengyel made his Slug technique completely patent-unencumbered ( https://terathon.com/blog/decade-slug.html ) . As long-time graphics programmers and open source contributors, especially around OpenSceneGraph, VulkanSceneGraph, and related visualization work, we were not going to let that sit untouched for long. On March 19th we started with a few proof-of-concept demos and began digging into the Slug algorithm in detail. Our goal was to take the core idea behind Slug’s high-quality GPU glyph rendering and see how far we could push it outside its original text-rendering use case.[…]
Eric Graham’s 1987 Amiga Juggler raytracer (Part 2): Porting to SDL
Eric Graham’s 1987 Amiga Juggler raytracer (Part 2): Porting to SDL In Part 1 of this blog series, we recovered the disk image, extracted the source files, and received permission to publish Eric Graham’s 1987 Juggler raytracer source. At that point, we have a snapshot of history that can be viewed from afar, like a[…]
Recovering Eric Graham’s 1987 Amiga Juggler raytracer source code
Recovering Eric Graham’s 1987 Juggler raytracer source code AlphaPixel often gets involved with modernizing and updating old performance and graphics code. Sometimes that means client work under NDA. But sometimes it means a fun side quest in the mystical realms of curiosity, preservation, and the practical problem of getting old data into a form that can be read and used on a current machine. Today let’s talk about Amiga Juggler ( https://en.wikipedia.org/wiki/Sculpt_3D ). The Juggler animation was ground-breaking and Earth-shattering. Even the Amiga’s creators (Commodore) didn’t believe it had been made on an Amiga. They thought the actual computation work[…]
