Two-point perspective has one set of lines parallel to the picture plane and two sets oblique to it. Parallel lines oblique to the picture plane converge to a vanishing point, which means that this set-up will require two vanishing points. Walls in 2-point perspective, converging toward two vanishing points.
Meridian convergence. True north, magnetic north and grid north. Imagine as if you were somewhere on Earth (easy to imagine I guess), and you have one world map on one hand and a compass on the other. GRID NORTH: the map you are holding has probably some horizontal and vertical lines. The direction of every vertical line indicates the grid north.
