Which perspective uses a single vanishing point on a horizon line?

• A. One-Point Perspective
• B. Two-Point Linear Perspective
• C. Three-Point Perspective
• D. Isometric Projection

Answer: (A)

One-point perspective is defined by a single vanishing point on the horizon line. When you look straight at a scene, all lines that recede away from you and are parallel to each other converge toward that one point, which sits on the horizon—your eye level. This setup makes depth read clearly: objects get smaller as they move toward the vanishing point, and the space inside a room or along a straight road typically collapses toward that central point. It’s a common choice for viewing straight-on scenes like corridors or the interior of a room.

Two-point perspective, in contrast, uses two vanishing points on the horizon to depict a corner view where two sets of parallel lines recede at different angles. Three-point perspective adds a third vanishing point for the vertical dimension when looking up or down. Isometric projection avoids vanishing points altogether, keeping all three axes parallel and equally foreshortened, so depth isn’t conveyed through converging lines.
