Main Point (Perspective)
Introduction
The conic perspective is a graphic representation system based on the projection of a three-dimensional body on a plane "Plane (geometry)"), using projecting lines that pass through a point; place from which the observer is supposed to look. The final result is a representation in the realistic vision plane obtained when the eye is at said point, a place from which the sensation of being inside the represented image increases.
Filippo Brunelleschi in the Quattrocento was the first to formulate the laws of conical perspective in his drawings of buildings in plan and elevation, indicating the lines that lead to the vanishing point.
Applications
Used in architecture, civil engineering and interior design to represent buildings, views of structures and volumes. It is the one that most closely approximates real vision, and is equivalent to the image we observe when looking at an object with only one eye. It allows us to perceive spatial depth similar to stereoscopic vision.
The computer programs "Program (computing)") perform graphic simulations by generating flat images using geometric algorithms. It is common to combine the rendering of surfaces and textures at the same time "Texture (computer graphics)"), giving the final image a photorealistic appearance.
It is frequently used in posters of real estate complexes and buildings that are under construction, since it shows in a realistic way what the new work will be like.
Geometric construction
Contenido
En la construcción geométrica de las perspectivas cónicas[1] se pueden encontrar dos métodos. El primero, que podría denominarse “método proyectivo”, se basa en un sistema de proyección cónica, inspirado en el sistema óptico visual. El segundo, es el “método directo”. En este caso se trabaja directamente sobre la imagen atendiendo a diferentes condiciones geométricas que se denominan “leyes perspectivas”. Este método, emparentado con la observación del natural, también debe cumplir condiciones geométricas de trazado, si se quiere realizar una expresión coherente y exacta del espacio representado.[2].
