perspektiiviprojektsioon

Perspektiiviprojektsioon, also known as perspective projection or vanishing point projection, is a method used in geometry and computer graphics to represent three-dimensional objects on a two-dimensional plane, mimicking how the human eye perceives depth and distance. Unlike parallel projection, where parallel lines remain parallel in the projection, perspective projection causes parallel lines to converge at a vanishing point. This creates a more realistic visual effect by diminishing the apparent size of objects as they recede into the distance.

There are different types of perspective projection based on the number of vanishing points. One-point perspective has a single vanishing point, typically used when viewing an object directly face-on, such as a road stretching into the distance. Two-point perspective involves two vanishing points, used when viewing an object at an angle, like a building corner. Three-point perspective incorporates a third vanishing point, often used for extreme viewpoints, such as looking up at a tall skyscraper or down from a great height, and it introduces a sense of extreme foreshortening. The principles of perspektiiviprojektsioon are fundamental to drawing, painting, architectural renderings, and the creation of realistic virtual environments in video games and simulations.
