Font Rendering: Freetype vs Signed Distance Field

[Dark_Photon]

@sckorpio

My doubts are that i am very confused with using Freetype and SDF:

Feel free to websearch for it. Start with some of what’s already out there for this:

• Freetype: create Signed Distance Field based font
• Freetype GL - A C OpenGL Freetype engine
  (for example, see: distance-field*.{h,c} and edtaa3func : Distance field computation)
• makeglfont - A small utility that creates a signed distance field PNG from a TrueType or an OpenType font file.
• Anti-aliased Euclidean distance transform
• Font Rendering is Getting Interesting
