I'm researching text rendering techniques for 3D applications, and I'm having a hard time finding information on the topic. Do you know of any other methods of text rendering that are actually used in current games or have a historical significance?
So far I have:
- Using prerendered bitmaps of glyphs / strings as textures,
- converting the glyph vectors to triangle meshes and rendering it as such,
- signed distance fields (popularized by Valve's paper),
I haven't managed to find anything else though.
Does anyone know what large engines, such as Source, Unreal, Unity, etc. use?
Sources would also be greatly appreciated.
