Not sure if I understand this correctly - the transformation on this slide(translate, and rotation it mentioned) will happen to both the camera and the objects? Then why objects need to take inverse transformations in the next slide?

@peanut The camera doesn't really exist. The only thing that really exists are the coordinates that describe objects. So, to simulate a camera you apply the inverse transformation to the objects. This transformation isn't actually getting applied to a "camera" anywhere (i.e., there is no other data stored in memory that represents the camera; just data representing the objects).
