One-Point Perspective

One-point perspective is the trick that makes a flat drawing look deep. The whole system hangs on a single dot: the vanishing point, usually on the horizon line at eye level. The rule is simple. Anything flat and facing you (the front of a building, a poster) stays drawn true, with horizontal and vertical edges. But anything running away from you into the distance (the sides of a road, the tops and bottoms of walls) is drawn as a line aiming straight at the vanishing point. Parallel rails in real life appear to converge at that dot, just like train tracks seeming to meet far away. Things also get smaller and closer together as they approach the point. Master that one dot and a street, a room, or a hallway snaps into believable 3D on a 2D page.

Same topic, fresh practice—does not count as an adaptation.

Practice building on this note. If you publish, it can show “Based on” and add an adaptation.

Explain how you'd draw a straight road with lamp posts receding into the distance using one vanishing point.

Doesn't mention when you'd need two- or three-point perspective instead.
Could clarify the role of the horizon line as eye level.
