Pathfinder is a GPU vector renderer developed at Mozilla, this post details some of the methods it uses.

GPU font rendering using an Loop-Blinn and algorithm reminiscent of stencil shadow volume rendering.

Loop-Blinn curve rendering for displaying vector graphics on the GPU.

One of the more advanced text rendering algorithms, by Eric Lengyel. Patented.

GLyphy represents a SDF using actual vectors submitted to the GPU. This results in very high quality rendering, though at a much higher runtime cost.

This is a utility for generating signed distance fields from vector shapes and font glyphs.
