The logical data model of vector graphics is based on the mathematics of coordinate geometry, in which shapes are defined as a set of points in a two- or three-dimensional cartesian coordinate system, as p = ( x, y) or p = ( x, y, z).

This can lead to some confusion in disciplines in which both meanings are used. Vector graphics are based on the mathematics of analytic or coordinate geometry, and is not related to other mathematical uses of the term vector. Some application domains, such as geographic information systems (GIS) and graphic design, use both vector and raster graphics at times, depending on purpose. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D rendering, and typography, but is entirely inappropriate for applications such as photography and remote sensing, where raster is more effective and efficient.

While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. Example showing comparison of vector graphics and raster graphics upon magnification For other uses, see Vector graphics (disambiguation). See the basic examples below.This article is about computer illustration. However, vectors should be used at radical scale or for clarity of defined edges in simple shapes, such as logos and illustrations. If something requires more detail at an adequate scale, raster images are optimum. Raster images should be used for photos while vectors should be used for logos and illustrations. Because the scaling versatility, vectors are excellent for logos, illustrations, sign writing and embroidery.

SVG, EPS, PDF and AI are common file formats for vector graphics. Often containing less detail than a raster image, a vector will retain appearance regardless of size and can be scaled infinitely.Īlthough you can include gradients and shadows in a vector, a true vector graphic is comprised of line art that is filled with colour. Vector images are made up of points, lines, and curves that are based upon mathematical equations, rather than pixels.

For digital deliverables a 72dpi is sufficient whereas print requires a minimum of 300dpi.

T hey cannot be scaled without sacrificing quality. The greater the dpi and dimensions, the higher the quality, and often the file size. Quality of a raster image is often dictated by the dpi (dots per inch) and the overall dimensions of the image. JPG, GIF and PNG are all examples of different types of raster files. This means raster images are capable of rendering complex, multi-coloured visuals, such as photographs. But, what do they actually mean and how are they different? Raster imagesĪ raster image (also known as bitmap) is made up of individual pixels and each of those pixels contributes to the overall image. So, raster vs vector? You may have heard of them and just nod politely when they are mentioned.
