  Chris Green’s #pdf #graphics #paper on magnified rendering of line-art textures using #shaders to bilinear-filter a low-resolution "signed distance field" (#SDF) texture and then threshold it (“alpha testing”). Seems like it could be applicable to raster-to-vector conversion (e.g. potrace). (The file is rather heavy for viewing in xpdf; recommend evince or a similar prefetching PDF viewer.)
