In one-point perspective, where is the vanishing point located?

In one-point perspective, the vanishing point is located on the horizon line. This technique creates the illusion of depth and space in a drawing by allowing parallel lines to converge at a single point on the horizon. The horizon line represents the viewer's eye level, and placing the vanishing point here ensures that objects recede into the distance accurately, maintaining the perspective that objects appear smaller as they move away from the viewer.

When the vanishing point is on the horizon line, all lines parallel to the viewer's line of sight will recede towards this point. This is crucial for representing environments, roads, and buildings in a realistic manner from a particular viewpoint.

The other options suggest that the vanishing point is placed above or below the horizon line or at the edge of the drawing, which would distort the perspective and not provide a true representation of depth.
