Reference shader implementations of the Slug algorithm for rendering vector fonts directly on the GPU using quadratic Bézier curve evaluation. The code is written in HLSL and accompanies a 2017 JCGT paper, with the associated patent dedicated to the public domain.

Use cases

• render text with GPU-accelerated font rasterization
• draw anti-aliased vector glyphs in a game engine
• implement high-quality font rendering in a custom graphics pipeline
• render scalable vector graphics on the GPU
• avoid CPU-based glyph atlas rasterization
• study GPU font rendering algorithms

When to choose

• you need high-quality, resolution-independent text rendering on the GPU
• you are building a custom rendering engine and want to avoid SDF or CPU rasterization artifacts
• you want a public-domain font rendering algorithm without patent risk

When to avoid

• you need a drop-in text rendering solution with font hinting support
• your target platform lacks programmable GPU shader support
• you need a complete font library with layout, shaping, and fallback handling
