Text Rendering Notes

Significant Repos

fontstash
Supported by sokol: sokol/util/sokol_fontstash.h
There are several forks for fonstash... Going to elabroate on them in a separate file

ColleagueRiley/RFont
Claims to target better perforamnce than fontstash. Decided to directly intergrate stb_truetype.h instead of keeping it separate (There is an option to define RFONT_EXTERNAL_STB).

jtsiomb/libdrawtext

kevinmkchin/vertext

hypernewbie/VEFontCache
(Also looks very good..., but it uses c++, easy to port however since its 1691 lines...)

• Ed94/VEFontCache-Odin: Ended up porting & overhauled this to Odin-lang

fontdue
(Self-proclaimed "fastest rasterizer")

Industry standard (free if you negotiate use on a free purpose, porting interface to X-Lang is problably non-trivial)

Original Notes Header

The goal here was to find some solution that was small and preferrably interopped well with odin-lang. So, everything that was either not written in C or was not going to be an easy port, was ignored.

Now I just keep this in sync with anything I find while working on my fork of VEFontCache.

Interesting...
