Perspective projection

In the real world, parallel lines converge as they get farther from the viewer, like a road going to the horizon. To replicate that, we use perspective projection, where the distance and angles are not preserved, and parallel lines do not remain parallel — instead, they converge at the center of the projection. The perspective projection depends on the relative position of the eye and the view plane. This projection includes one-point, 2-point, and 3-point perspective projection types, each defined by the number of vanishing points.^[1]
