In this tutorial I go over how to create a game camera in OpenGL using LWJGL3. I cover what a projection matrix is, what a view matrix is, and how they tie together to create a unified game camera. I also go over the mathematical process of transforming the world space coordinates to normalized device coordinates using these matrices. And lastly, I briefly describe what shader uniforms are, and how we can use them to upload our camera data to the GPU and then draw our world in world coordinates instead of normalized device coordinates.
