# SDF font atlas generation tool

Atlas generation tool for the [font rendering demo](https://github.com/astiopin/webgl_fonts).

The algorithm described [here](https://astiopin.github.io/2019/01/06/sdf-on-gpu.html).

Mostly for educational purposes since the algorithm is performant enough for generating font atlases at runtime.

# Dependencies

GLFW
