From one of hundreds or thousands of articles about the "problem" of converging lines when photographing many objects in the real world.
"When photographing a tall building, you'll often tilt the camera upward both in order for the building to fit into the frame and in order for you to get rid of any unwanted foreground.
This is when
the vertical lines of the building converge towards the top in the photo."

The ability to correct for "converging lines" is one reason many architectural photographers have used view cameras or tilt-shift lenses.
