Perspective (graphical) in the context of "Perpendicular"

A first-person narrative (also known as a first-person perspective, voice, point of view, etc.) is a mode of storytelling in which a storyteller recounts events from that storyteller's own personal point of view, using first-person grammar such as "I", "me", "my", and "myself" (also, in plural form, "we", "us", etc.). It must be narrated by a first-person character, such as a protagonist (or other focal character), re-teller, witness, or peripheral character. Alternatively, in a visual storytelling medium (such as video, television, or film), the first-person perspective is a graphical perspective rendered through a character's visual field, so the camera is "seeing" out of a character's eyes.

A classic example of a first-person protagonist narrator is Charlotte Brontë's Jane Eyre (1847), in which the title character is telling the story in which she herself is also the protagonist: "I could not unlove him now, merely because I found that he had ceased to notice me". Srikanta by Bengali writer Sarat Chandra Chattopadhyay is another first-person perspective novel which is often called a "masterpiece". Srikanta, the title character and protagonist of the novel, tells his own story: "What memories and thoughts crowd into my mind, as, at the threshold of the afternoon of my wandering life, I sit down to write the story of its morning hours!"

Filippo di ser Brunellesco di Lippo Lapi (1377 – 15 April 1446), commonly known as Filippo Brunelleschi (/ˌbruːnəˈlɛski/ BROO-nə-LESK-ee; Italian: [fiˈlippo brunelˈleski]) and also nicknamed Pippo by Leon Battista Alberti, was an Italian architect, designer, goldsmith, and sculptor. He is considered to be a founding father of Renaissance architecture. He is recognized as the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, and for the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. Most surviving works can be found in Florence.

De pictura (English: "On Painting") is a treatise or commentarii written by the Italian humanist and artist Leon Battista Alberti. The first version, composed in Latin in 1435, was not published until 1450. It is one of his three treatises on art; the other two are De statua and De re aedificatoria, that would form the Renaissance concept for the fine arts: painting, sculpture, and architecture.

An art movement is a tendency or style in art with a specific art philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered a new avant-garde movement. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality (figurative art). By the end of the 19th century many artists felt a need to create a new style which would encompass the fundamental changes taking place in technology, science and philosophy (abstract art).

Abstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Abstract art, non-figurative art, non-objective art, and non-representational art are all closely related terms. They have similar, but perhaps not identical, meanings.

Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th century, many artists felt a need to create a new kind of art which would encompass the fundamental changes taking place in technology, science and philosophy. The sources from which individual artists drew their theoretical arguments were diverse, and reflected the social and intellectual preoccupations in all areas of Western culture at that time.

Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed.

Technical drawing is essential for communicating ideas in industry and engineering.To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128.

In art, a study is a drawing, sketch or painting done in preparation for a finished piece, as visual notes, or as practice. Studies are often used to understand the problems involved in rendering subjects and to plan the elements to be used in finished works, such as light, color, form, perspective and composition. Studies can have more impact than more-elaborately planned work, due to the fresh insights the artist gains while exploring the subject. The excitement of discovery can give a study vitality. When layers of the work show changes the artist made as more was understood, the viewer shares more of the artist's sense of discovery. Written notes alongside visual images add to the import of the piece as they allow the viewer to share the artist's process of getting to know the subject.

Studies inspired some of the first 20th century conceptual art, where the creative process itself becomes the subject of the piece. Since the process is what is all-important in studies and conceptual art, the viewer may be left with no material object of art.

Piero della Francesca (/ˌpjɛəroʊ ˌdɛlə frænˈtʃɛskə/ PYAIR-oh DEL-ə fran-CHESK-ə, US also /- frɑːnˈ-/ -⁠ frahn-; Italian: [ˈpjɛːro della franˈtʃeska] ; né Piero di Benedetto de' Franceschi; c. 1415 – 12 October 1492) was an Italian painter, mathematician and geometer of the Early Renaissance, nowadays chiefly appreciated for his art. His painting is characterized by its serene humanism, its use of geometric forms and perspective. His most famous work is the cycle of frescoes The History of the True Cross in the Basilica of San Francesco in the Tuscan town of Arezzo.

Renaissance technology was the set of European artifacts and inventions which spread through the Renaissance period, roughly the 14th century through the 16th century. The era is marked by profound technical advancements such as the printing press, linear perspective in drawing, patent law, double shell domes and bastion fortresses. Sketchbooks from artisans of the period (Taccola and Leonardo da Vinci, for example) give a deep insight into the mechanical technology then known and applied.

Renaissance science spawned the Scientific Revolution; science and technology began a cycle of mutual advancement.
