T-square. A T-square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. The instrument is named after its resemblance to the letter T, with a long shaft called the "blade" and a short shaft called the "stock" or "head". T-squares are available in a range of sizes, with ...
Technical drawing tool. Appearance. Drafting tools may be used for measurement and layout of drawings, or to improve the consistency and speed of creation of standard drawing elements. Tools such as pens and pencils mark the drawing medium. Other tools such as straight edges, assist the operator in drawing straight lines, or assist the operator ...
The rule of thirds is a "rule of thumb" for composing visual images such as designs, films, paintings, and photographs. [3] The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced horizontal lines and two equally spaced vertical lines, and that important compositional elements should be ...
Horizontal and vertical edges in the object are represented by horizontals and verticals in the drawing. Lines leading away into the distance appear to converge at a vanishing point. All horizontals converge to a point on the horizon, which is a horizontal line at eye level. Verticals converge to a point either above or below the horizon.
Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment.
There are different types of lines artists may use, including, actual, implied, vertical, horizontal, diagonal and contour lines, which all have different functions. [3] Lines are also situational elements, requiring the viewer to have knowledge of the physical world in order to understand their flexibility, rigidity, synthetic nature, or life. [1]
Bresenham's line algorithm. Bresenham's line algorithm is a line drawing algorithm that determines the points of an n -dimensional raster that should be selected in order to form a close approximation to a straight line between two points. It is commonly used to draw line primitives in a bitmap image (e.g. on a computer screen ), as it uses ...
In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel -based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases). Basic algorithms rasterize lines in one color. A better representation with multiple color ...
