Since you left this "optimize me" comment here: https://github.com/RandyGaul/cute_headers/blob/755849fc2819d... See an optimized quaternion multiplication implementation in SSE by me here: https://stackoverflow.com/questions/18542894/how-to-multiply...

I was just taking a look and couldn't help but notice the switch statement for your operator[], which likely causes a lot of unnecessary bad speculation at runtime: https://github.com/RandyGaul/cute_headers/blob/755849fc2819d... I fixed this exact problem in a highly used library in high energy physics: https://gitlab.cern.ch/CLHEP/CLHEP/-/commit/5f20daf0cae91179... Many believe the C++ compiler will magically optimize the switch away, but in some cases, like the example above for CLHEP, it doesn't happen, so you end up with bad performance.

BTW, the basic idea of keeping a texture atlas that contains a cache of the most used render elements isn't really that novel. It has already been done way before in the past by game engine devs who were trying to create 2D sprite renderers that automatically batch sprite textures to save draw calls (on runtime without any preprocessing step). Some examples I could find: - https://docs.cocos.com/creator/2.4/manual/en/advanced-topics... - https://github.com/mattdesl/gl-sprite-batch - https://github.com/RandyGaul/cute_headers/blob/master/cute_s... It's a simple and relatively straightforward approach that a sufficiently bright programmer would come up in their own while looking at the design constraints though, so overall I find it a bit meaningless to find the ultimate person for the "original idea".

The verdict for indie developers (not using Unity/Unreal) seems: just bite the bullet and license FMOD (or Wwise or any of the popular proprietary audio engies). I was actually searching for a good open-source audio library to use, and found out that my options aren't that good. SoLoud is a pain in the ass to install and integrate into an existing codebase, and OpenAL doesn't have any good implementations available (either proprietary or LGPL). I'm now just using a simple single-header audio library in cute_headers (https://github.com/RandyGaul/cute_headers/blob/master/cute_s...), but will probably switch to MiniAudio once the high-level API is finished (https://github.com/mackron/miniaudio/issues/196)

Check this: http://utf8everywhere.org/ Basically store the text as char arrays, and convert them when needed. Meanwhile, you could use this single file header: https://github.com/RandyGaul/cute_headers/blob/master/cute_u...

Another key use case for header-only libs is for games and projects where you need to do rapid prototyping. A lot of game utilities are distributed this way, e.g. https://github.com/RandyGaul/cute_headers
