Pathfinder 3 is a fast GPU-based rasterizer for fonts and vector graphics, usable from Rust or C/C++ via a canvas-like API. It supports OpenGL 3.0+, OpenGL ES 3.0+, WebGL 2, and Metal, with compute-shader and hardware rasterization backends.

Use cases

• render vector graphics on the GPU in a Rust app
• fast font rendering with subpixel antialiasing
• render SVG efficiently at high performance
• replace CPU rasterizers with GPU-accelerated 2D rendering
• embed canvas-style 2D drawing in a C/C++ application
• render text with hinting and gamma correction on LCD screens

When to choose

• you need high-performance 2D vector or font rendering accelerated by the GPU
• you want a canvas-like API in Rust or C/C++
• you need high-quality antialiasing or advanced text rendering features
• your workload involves many overlapping vector paths or SVG content

When to avoid

• you need a fully complete, production-hardened rasterizer - the project is under heavy development and incomplete in areas
• you need Direct3D or Vulkan backends - none exist yet
• you only need simple CPU-based rendering without GPU dependencies
• you need complete C bindings - they are less mature than the Rust API
