Generates multi-channel signed distance fields (MSDFs) from vector shapes and fonts for sharp, efficient real-time graphics rendering.
MSDFgen is a C++ library and command-line utility that generates signed distance fields (SDFs) from vector shapes and font glyphs. It specializes in multi-channel SDFs, a technique that uses multiple color channels to preserve sharp corners and edges, solving a common limitation of traditional monochrome SDFs. This enables high-quality, efficient rendering of vector graphics and text in real-time applications like video games and graphical user interfaces.
Graphics programmers, game developers, and UI engineers who need to render crisp vector shapes and text in real-time applications. It's particularly valuable for projects requiring high-quality font rendering or scalable vector graphics with minimal performance overhead.
Developers choose MSDFgen for its superior multi-channel SDF algorithm, which produces sharper corners and more accurate shapes than conventional SDF methods. It offers a robust, dependency-light core library, flexible input/output options, and is widely adopted as the standard tool for generating high-quality distance fields in the graphics community.

Implements a novel multi-channel SDF method that perfectly preserves sharp corners, as demonstrated in comparison images and detailed in the author's Master's thesis.
Supports font glyphs via FreeType, SVG files, and custom shape descriptions, allowing generation from diverse vector art without conversion.
Provides both a comprehensive command-line tool for quick batch processing and a C++ library for integration into custom graphics pipelines.
Includes test rendering utilities to preview generated distance fields, ensuring accuracy before deployment in real-time applications.
Requires external libraries like FreeType, TinyXML2, and libpng, which can complicate build processes, especially in cross-platform or embedded environments.
Only processes the last vector path in SVG files, as noted in the README, making it unsuitable for SVGs with multiple layered elements.
Users must write custom GLSL or HLSL shaders to sample and render MSDFs, adding development overhead compared to drop-in rendering solutions.
