Slughorn, Slug font/glyph render lib for OpenGL/OSG/Vulkan/GPU APIs (MIT lic))

24 days ago

Slughorn is an open-source C++20 library designed to extend the Slug GPU curve-rendering technique beyond text, focusing on vector graphics like glyphs, SVG paths, and icons.
It is MIT-licensed, requires no third-party dependencies, and supports import from sources like FreeType (for COLRv0/v1 emoji), NanoSVG, Skia, Cairo, and Blend2D, with optional features using submodules.
The library acts as an input/adapter layer, providing Slug-compatible data for integration into existing renderers (e.g., OpenGL, Vulkan, DirectX) and scene graphs, rather than being a standalone renderer.
It emphasizes high-quality, GPU-rendered curves to avoid artifacts from texture atlases or SDFs, making it suitable for 3D UI, AR/VR, HUDs, maps, and technical visualization where exact vector rendering is crucial.
