I am not an expert in the area, just somebody who read up on it after realizing desktop in VR does not work out for me (and usually low res is not a problem, so it is about font aliasing).
Thanks for the link! The path based approach has been of interest to me, but I wasn't aware of an implementation other than Slug, which I have been avoiding. Guess I can finally do some real research on that topic now! :D
SDF is probably still the most realistic path for now, but I guess that may depend a bit on what comes up :)
Something like https://github.com/servo/pathfinder (newer) and as you mentioned SDF (older) are the latest approaches.
