In this video I describe the Camera/View space and provide a full overview of all the coordinate system transitions that are involved in 3D rendering. For the camera I use a well known model called the UVN camera and I describe the steps for creating the camera/view transformation matrix based on that model.

🔥 I'm using the following books as background information for my tutorials and I highly recommend them for learning more about OpenGL and Vulkan.
