Sciography
Sciography
Sciography (pronounced: /saɪˈɒɡrəfi/), also known as shadow casting or shadow drawing, is a branch of science that deals with the study of shadows. The term is derived from the Greek words "skia" meaning shadow, and "graphein" meaning to write or draw.
Sciography is primarily used in the fields of architecture, art, and design to depict the depth and solid appearance of objects in a two-dimensional representation. It is a crucial aspect of perspective drawing, where it helps in creating a realistic representation of light and shadow.
History
The concept of sciography has been in existence since ancient times, with early civilizations using it to create sundials and track the movement of celestial bodies. However, the term "sciography" itself was coined in the 19th century.
Application
In architecture, sciography is used to depict how shadows will fall on a building or structure at different times of the day and year. This helps architects design buildings that make optimal use of natural light. In art and design, sciography is used to create a sense of depth and three-dimensionality in two-dimensional drawings and paintings.
