Texture (painting)

Texture in painting is the look and feel of the canvas. It is based on the paint, and its application, or the addition of materials such as ribbon, metal, wood, lace, leather and sand. The concept of 'painterliness' also has bearing on texture. The texture stimulates two different senses; sight and touch. There are four types of texture in art: actual texture, simulated texture, abstract texture, and invented texture.

Actual texture

This is a combination of how the painting looks, and how it feels to the touch. It is associated both with the heavy buildup of paint, such as an impasto effect, or the addition of materials.

Simulated texture

Creating the visual effect of texture without actually adding texture. For instance, a texture created to look like something other than paint on a flat surface. An example is Cataract 3, painted in 1967 by Bridget Riley, which creates the illusion of ripples in the paper through the repetition of lines.

Implied texture

Texture that does not directly represent the object it is connected with but the concept of the object is translated in textural patterns.

Texture mapping

Texture mapping is a method for adding detail, surface texture (a bitmap or raster image), or color to a computer-generated graphic or 3D model. Its application to 3D graphics was pioneered by Edwin Catmull in 1974.

Originally a method that simply wrapped and mapped pixels from a texture to a 3D surface - now more technically called diffuse mapping to distinguish it from more complex mappings - in recent decades the advent of multi-pass rendering and complex mapping such as height mapping, bump mapping, normal mapping, displacement mapping, reflection mapping, mipmaps, occlusion mapping, and many other complex variations on the technique have made it possible to simulate near-photorealism in real time, by vastly reducing the number of polygons and lighting calculations needed to construct a realistic and functional 3D scene.

STAR (interbank network)

STAR is an interbank network and EFTPOS network in the United States. It is the largest American interbank network, with 2 millionATMs, 134 million cardholders and over 5,700 participating financial institutions. The STAR Network began in 1984 and was acquired by First Data Corporation in 2003. The network is owned and operated by STAR Networks, a subsidiary company of First Data.

Mergers

The network has existed since the 1980s, and has since included several other networks, mostly in the 2000s:

Alert (sternwheeler 1865)

Alert was a sternwheeler steamboat which operated on the Willamette River, in Oregon, United States, from 1865 to 1875. Originally built for and owned by the Willamette Steam Navigation Co., it was soon acquired by the People's Transportation Company, a steamboat line which held a near-monopoly on Willamette River transportation. This vessel was rebuilt in 1871, and ran until 1875, when it was dismantled.

Construction and dimensions

Alert was built at Oswego, Oregon, in 1865 by the firm of Paquet & Brown, and launched on December 8, 1865.Alert was 135 ft (41.1 m) long, exclusive of the extension of the main deck over the stern, called the "fantail" on which the stern-wheel was mounted.Alert had a beam (width) of 25 ft (7.6 m) and depth of hold of 5 ft (1.5 m).

Alert measured out at 340.83 tons according to the official merchant vessel registry. The official merchant vessel registry number was 1233.

Alert was driven by two single-cylinder steam engines, horizontally mounted, each with a cylinder bore of 16.5 inches and a piston stroke of 60 inches. In 1874, the steam engines of Alert developed 74 horsepower.
