A comprehensive comparison of GPU text rendering techniques including SDF, MSDF, Slug, Texture Atlas, and Rive. The article highlights Slug's approach of rendering glyphs directly from vector outlines in the fragment shader without texture atlases, made freely available after Eric Lengyel dedicated his 2019 patent to the public domain in March 2026.
Background
GPU 文本渲染在游戏引擎和 UI 框架中一直是性能瓶颈。传统方案通过预烘焙字形纹理（texture atlas）解决，但牺牲了质量和灵活性。Slug 算法代表了一种无需预烘焙的原生 GPU 渲染方案。
