## Description

Pathfinder is a GPU vector rendering engine and 3D vector graphics rasterizer. It functions as a cross-language rendering library that utilizes GPU compute shaders to convert vector paths and typography into pixel data.

The engine projects vector paths and text into three-dimensional environments for spatial user interfaces. It includes a GPU-accelerated typography engine that employs subpixel antialiasing and gamma correction to maintain visual clarity on screens.

The project provides high-precision antialiasing through fractional area coverage and manages rendering overhead using tile-based occlusion culling. It supports vector animation playback and exposes its functionality to applications in various programming languages via stable binary bindings.
