  Project mention: Trouble calculating projection matrix | /r/GraphicsProgramming | 2023-06-20

  If you don't like using heavy libraries such as glm, I recommend looking at HandmadeMath. It is a single file c/c++ math library for graphics programming. You can just drop it into your project. It's lightweight and will save you a lot of time implementing the math yourself. In a lot of cases, it actually uses optimized solutions to save computation time (same with the glm).
