Animations Wallpapers Biography:
The earliest graphics known to anthropologists studying prehistoric periods are cave paintings and markings on boulders, bone, ivory, and antlers, which were created during the Upper Palaeolithic period from 40,000–10,000 B.C. or earlier. Many of these were found to record astronomical, seasonal, and chronological details. Some of the earliest graphics and drawings known to the modern world, from almost 6,000 years ago, are that of engraved stone tablets and ceramic cylinder seals, marking the beginning of the historic periods and the keeping of records for accounting and inventory purposes. Records from Egypt predate these and papyrus was used by the Egyptians as a material on which to plan the building of pyramids; they also used slabs of limestone and wood. From 600–250 BC, the Greeks played a major role in geometry. They used graphics to represent their mathematical theories such as the Circle Theorem and the Pythagorean theorem.
In art, "graphics" is often used to distinguish work in a monotone and made up of lines, as opposed to painting.
[edit] Drawing
Main articles: Drawing and Technical drawing

Drawing generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface. Common tools are graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, pastels, and markers. Digital tools which simulate the effects of these are also used. The main techniques used in drawing are line drawing, hatching, crosshatching, random hatching, scribbling, stippling, blending, and shading.
Drawing is generally considered distinct from painting, in which colored pigments are suspended in a liquid medium and are usually applied with a brush. Notable great drawers include Michelangelo, Rembrandt, Raphael and Leonardo da Vinci.
Many people choose drawing as a main art style, or they may use it to make sketches for paintings, sculptures and other types of art. The other term is Engineering Graphics, preferably the language of engineers that simulates Three Dimensional capability of engineer to plan and Implement his ideas. It comprises Projection, Development, Perspective, Section, Intersection, and Isometric ideations.
[edit] Printmaking
Main article: Printmaking
Woodblock printing, including images is first seen in China after paper was invented (about A.D. 105). In the West the main techniques have been woodcut, engraving and etching, but there are many others.
[edit] Etching
Main article: Etching
Etching is an intaglio method of printmaking in which the image is incised into the surface of a metal plate using an acid. The acid eats the metal, leaving behind roughened areas, or, if the surface exposed to the acid is very thin, burning a line into the plate. The use of the process in printmaking is believed to have been invented by Daniel Hopfer (c. 1470–1536) of Augsburg, Germany, who decorated armour in this way.
Etching is also used in the manufacturing of printed circuit boards and semiconductor devices.
