Plotters draw lines on paper using a pen, or in some applications, use a knife to cut a material like vinyl or leather. In the latter case, they are sometimes known as a cutting plotter . In the past, plotters were used in applications such as computer-aided design , as they were able to produce line drawings much faster and of a higher quality ...
Another use of line in graphics is the ability to help suggest a tone or feeling in a work. Vertical lines can be used to create a sense of strength or stability. An example of this could be a row of trees in a picture creating a series of vertical lines. Horizontal lines can be used to create a feeling of calm, peace or passiveness.
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.
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.
A cutaway drawing is a technical illustration, in which part of the surface of a three-dimensional model is removed in order to show some of the model's interior in relation to its exterior. The purpose of a cutaway drawing is to "allow the viewer to have a look into an otherwise solid opaque object.
Two methods of drawing smooth curves in manual drafting are the use of French curves and flat splines (flexible curves). A French curve is a drawing aid with many different smoothly-varying radiused curves on it; the manual drafter can fit the French curve to some known reference points and draw a smooth curved line between them.
Specifically, draw a diagonal line connecting two points on the diagram so that every other point is either on or to the right and above it. There is at least one such line if the curve passes through the origin. Let the equation of the line be qα+pβ=r. Suppose the curve is approximated by y=Cx p/q near the origin.
The layout usually consists of evenly spaced horizontal lines, or feints, with vertical lines drawn to indicate margins, the middle of the page, or sections of a line. Graph paper has horizontal and vertical lines evenly spaced over the entire page to create a grid of squares and is used for drafting, drawing and plotting graphs. Often every ...
