What type of perspective is characterized by a single vanishing point?

One-point perspective is defined by the use of a single vanishing point located on the horizon line. This technique allows for a straightforward representation of space and depth, where lines converge towards that single point, creating the illusion of three-dimensionality on a two-dimensional surface. It's commonly used in artworks where the viewer is looking straight down a road, corridor, or any object that has a direct line of sight, enhancing the symmetry and depth of the composition.

In contrast, two-point perspective employs two vanishing points, which are typically placed on the horizon line, while three-point perspective adds a third vanishing point either above or below that line, allowing for further depth and more dramatic foreshortening. Isometric perspective, on the other hand, does not utilize vanishing points but instead maintains parallel lines that represent objects without the distortion of perspective, resulting in a more technical, diorama-like view. Thus, the defining feature of one-point perspective, as characterized by its use of a single vanishing point, sets it apart from these other forms of perspective.
