Finished something huge today, a positionable/modifiable camera! Each image can now have a unique position for the camera, as well as a rotated camera. I also added FOV which makes the camera zoom in or out. (Default set to 90). One big thing I had to deal with was the cross products. The cross product of two vectors returns one vector perpendicular to both original vectors, which was required to calculate the direction the camera was facing. The order of calculation matters a lot because incorrect cross products flipped the image upside down, inversed rotation and position, etc.
