I know there are a multitude of C++ math libraries out there, but my current project is C-only (C11).

So far I've made due with writing my own matrix/vector functions, but now I need to do the more complex operations like matrix rotation and quaternion multiplication... and I'd really rather focus on the project than painstakingly building a whole math library.

Does anyone know of any fast (game-usable, not academic) C-only stand-alone math libraries out there? I've done numerous searches, and haven't found much.

  • \$\begingroup\$ Yep, closing for "what technology to use". Unfortunately, question asking what technology to use are off-topic here. \$\endgroup\$ – Alexandre Vaillancourt May 31 '18 at 1:59
