Perspective drawing is a technique used in art and design to create the illusion of depth and space on a flat surface. By using a vanishing point, artists can depict how objects appear smaller as they recede into the distance, mimicking how the human eye perceives the world. This method involves drawing lines that converge at the vanishing point, which is typically located on the horizon line. One-point perspective and two-point perspective are common types, each offering different ways to represent three-dimensional objects realistically. This technique is essential in fields like architecture and illustration.
