Pointillism. Pointillism ( / ˈpwæ̃tɪlɪzəm /, also US: / ˈpwɑːn - ˌ ˈpɔɪn -/) [1] is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism.
The vanishing point theorem is the principal theorem in the science of perspective. It says that the image in a picture plane π of a line L in space, not parallel to the picture, is determined by its intersection with π and its vanishing point. Some authors have used the phrase, "the image of a line includes its vanishing point".
The dew point of a given body of air is the temperature to which it must be cooled to become saturated with water vapor. This temperature depends on the pressure and water content of the air. When the air is cooled below the dew point, its moisture capacity is reduced and airborne water vapor will condense to form liquid water known as dew. [ 1]
Richard Rorty was a prominent interpreter of Derrida's philosophy. His definition of deconstruction is that, "the term 'deconstruction' refers in the first instance to the way in which the 'accidental' features of a text can be seen as betraying, subverting, its purportedly 'essential' message."
Perspective (graphical) Linear or point-projection perspective (from Latin perspicere 'to see through') is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection. [citation needed][dubious – discuss] Linear perspective is an approximate representation, generally on a flat surface, of an ...
The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (also known as gasoline ), and combustible fuels, such as diesel . It is also used to characterize the fire hazards of fuels. Fuels which have a flash point less than 37.8 °C (100.0 °F) are called flammable, whereas fuels having ...
Nadir also refers to the downward-facing viewing geometry of an orbiting satellite, [2] such as is employed during remote sensing of the atmosphere, as well as when an astronaut faces the Earth while performing a spacewalk. A nadir image is a satellite image or aerial photo of the Earth taken vertically. A satellite ground track represents its ...
Intaglio ( / ɪnˈtælioʊ, - ˈtɑː -/ in-TAL-ee-oh, -TAH-; [ 1] Italian: [inˈtaʎʎo]) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. [ 2] It is the direct opposite of a relief print where the parts of the matrix that make the image ...
