Computer graphics images defined by points, lines and curves

Vector graphics, equally a grade of estimator graphics, is the set of mechanisms for creating visual images directly from geometric shapes defined on a Cartesian plane, such every bit points, lines, curves, and polygons. These mechanisms may include vector display and printing hardware, vector data models and file formats, and software based on these data models (specially graphic design software, estimator-aided design, and geographic information systems). Vector graphics is an alternative to raster graphics, each having advantages and disadvantages in general and in specific situations.^[1]

While vector hardware has largely disappeared in favor of raster-based monitors and printers,^[2] vector information and software continues to be widely used, especially when a high caste of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering science, architecture, surveying, 3D rendering, and typography, simply is entirely inappropriate for applications such equally photography and remote sensing, where raster is more effective and efficient. Some application domains, such every bit geographic data systems (GIS) and graphic design, use both vector and raster graphics at times, depending on purpose.

Vector graphics are based on the mathematics of analytic or coordinate geometry, and is not related to other mathematical uses of the term vector, including vector fields and vector calculus. This tin can lead to some confusion in disciplines in which both meanings are used.

Data model [edit]

The logical data model of vector graphics is based on the mathematics of coordinate geometry, in which shapes are defined as a set up of points in a ii- or iii-dimensional cartesian coordinate system, as p = (x, y) or p = (x, y, z). Because almost all shapes consist of an space number of points, the vector model defines a limited set of geometric primitives that tin be specified using a finite sample of salient points chosen vertices. For case, a foursquare tin can be unambiguously defined past the locations of three of its four corners, from which the software can interpolate the connecting boundary lines and the interior space. Because it is a regular shape, a square could also be defined past the location of one corner, a size (width=top), and a rotation angle.

The cardinal geometric primitives are:

A single signal
A Line segment, divers past 2 finish points, assuasive for a uncomplicated linear interpolation of the intervening line.
A Polygonal concatenation or polyline, a connected set of line segments, defined by an ordered list of points
A Polygon, representing a region of space, defined by its purlieus, a polyline with ancillary starting and ending vertices.

A variety of more than complex shapes may be supported:

Parametric curves, in which polylines or polygons are augmented with parameters to define a non-linear interpolation between vertices, including round arcs, cubic splines, Catmull–Rom splines, Bézier curves and bezigons
Standard parametric shapes in two or three dimensions, such every bit Circles, ellipses, squares, superellipses, spheres, tetrahedrons, superellipsoids, etc.
Irregular three-dimensional surfaces and solids, ordinarily defined as a connected set of polygons (e.g., a Polygon mesh) or as parametric surfaces (due east.thou., NURBS)
Fractals, often defined equally an iterated function arrangement

In many vector datasets, each shape can be combined with a fix of properties. The nearly mutual are visual characteristics, such equally color, line weight, or dash pattern. In systems in which shapes represent existent-world features, such as GIS and BIM, a variety of attributes of each represented feature tin can be stored, such as proper name, historic period, size, and so on.^[3]

In some Vector data, specially in GIS, information most topological relationships between objects may be represented in the information model, such as tracking the connections between route segments in a transport network.^[four]

If a dataset stored in one vector file format is converted to another file format that supports all the primitive objects used in that particular image, and then the conversion can be lossless.

Vector brandish hardware [edit]

Vector-based devices, such as the vector CRT and the pen plotter, direct control a cartoon mechanism to produce geometric shapes. Since vector display devices can define a line by dealing with just ii points (that is, the coordinates of each end of the line), the device can reduce the total amount of data information technology must deal with past organizing the image in terms of pairs of points.^[five]

Vector graphic displays were first used in 1958 by the United states of america SAGE air defense force system.^[half-dozen] Vector graphics systems were retired from the U.Southward. en route air traffic control in 1999.^{[ citation needed ]} Vector graphics were also used on the TX-ii at the MIT Lincoln Laboratory by computer graphics pioneer Ivan Sutherland to run his programme Sketchpad in 1963.^[vii]

Subsequent vector graphics systems, most of which iterated through dynamically modifiable stored lists of drawing instructions, include the IBM 2250, Imlac PDS-1, and December GT40. There was a video game panel that used vector graphics called Vectrex too as various arcade games like Asteroids, Infinite Wars, and many cinematronics titles such equally Rip-Off, and Tail Gunner using vector monitors.^[8] Storage scope displays, such as the Tektronix 4014, could display vector images but not modify them without first erasing the brandish. Nonetheless, these were never as widely used as the raster-based scanning displays used for television, and had largely disappeared by the mid-1980s except for specialized applications.

Plotters used in technical drawing still draw vectors straight to paper past moving a pen as directed through the two-dimensional infinite of the paper. Still, as with monitors, these have largely been replaced by the Wide-format printer that prints a raster image (which may be rendered from vector information).

Software [edit]

Because this model is useful in a variety of application domains, many different software programs have been created for drawing, manipulating, and visualizing vector graphics. While these are all based on the same bones vector data model, they can interpret and structure shapes very differently, using very different file formats.

Graphic pattern and illustration, using a Vector graphics editor or Graphic fine art software such every bit Adobe Illustrator. See Comparison of vector graphics editors for capabilities.
Geographic information systems (GIS), which tin can stand for a geographic characteristic past a combination of a vector shape and a set up of attributes.^[9] GIS includes vector editing, mapping, and vector spatial analysis capabilities.
Computer-aided design (CAD), used in applied science, architecture, and surveying. Building information modeling (BIM) models add together attributes to each shapes, similar to a GIS.
3D computer graphics software, including Computer animation.

File formats [edit]

This vector-based (SVG format) prototype of a round four-color swirl displays several unique features of vector graphics versus raster graphics: at that place is no aliasing forth the rounded edge (which would result in digital artifacts in a raster graphic), the color gradients are all smooth, and the user can resize the image infinitely without losing any quality.

Vector graphics are ordinarily plant today in the SVG, WMF, EPS, PDF, CDR or AI types of graphic file formats, and are intrinsically dissimilar from the more common raster graphics file formats such as JPEG, PNG, APNG, GIF, WebP, BMP and MPEG4.

The World wide web Consortium (W3C) standard for vector graphics is Scalable Vector Graphics (SVG). The standard is complex and has been relatively irksome to be established at to the lowest degree in part owing to commercial interests. Many web browsers now accept some support for rendering SVG information but full implementations of the standard are still insufficiently rare.

In recent years, SVG has become a significant format that is completely independent of the resolution of the rendering device, typically a printer or display monitor. SVG files are essentially printable text that describes both straight and curved paths, besides equally other attributes. Wikipedia prefers SVG for images such as simple maps, line illustrations, coats of arms, and flags, which generally are not like photographs or other continuous-tone images. Rendering SVG requires conversion to a raster format at a resolution appropriate for the electric current task. SVG is besides a format for animated graphics.

There is as well a version of SVG for mobile phones. In item, the specific format for mobile phones is called SVGT (SVG Tiny version). These images can count links and besides exploit anti-aliasing. They tin also be displayed as wallpaper.

CAD software uses its own vector data formats, unremarkably proprietary formats created by the software vendors, such as Autodesk'south DWG and public substitution formats such equally DXF. Hundreds of singled-out vector file formats have been created for GIS data over its history, including proprietary formats similar the Esri file geodatabase, proprietary but public formats like the Shapefile and the original KML, open source formats similar GeoJSON, and formats created by standards bodies like Elementary Features and GML from the Open Geospatial Consortium.

Conversion [edit]

The list of epitome file formats covers proprietary and public vector formats.

Detail can be added to or removed from vector art.

To raster [edit]

Modern displays and printers are raster devices; vector formats accept to be converted to a raster format (bitmaps – pixel arrays) earlier they tin be rendered (displayed or printed).^[10] The size of the bitmap/raster-format file generated by the conversion will depend on the resolution required, but the size of the vector file generating the bitmap/raster file will always remain the aforementioned. Thus, information technology is like shooting fish in a barrel to catechumen from a vector file to a range of bitmap/raster file formats but it is much more hard to go in the opposite direction, especially if subsequent editing of the vector motion picture is required. It might be an advantage to save an image created from a vector source file as a bitmap/raster format, considering different systems have dissimilar (and incompatible) vector formats, and some might non support vector graphics at all. All the same, one time a file is converted from the vector format, it is likely to be bigger, and information technology loses the advantage of scalability without loss of resolution. It will as well no longer be possible to edit individual parts of the image as discrete objects. The file size of a vector graphic epitome depends on the number of graphic elements it contains; it is a list of descriptions.

From raster [edit]

Printing [edit]

Vector art is platonic for printing since the fine art is made from a series of mathematical curves; it will print very crisply even when resized.^[11] For instance, i can print a vector logo on a small canvas of copy paper, so overstate the same vector logo to billboard size and go on the same well-baked quality. A low-resolution raster graphic would blur or pixelate excessively if it were enlarged from business organization card size to billboard size. (The precise resolution of a raster graphic necessary for high-quality results depends on the viewing distance; eastward.thou., a billboard may still appear to be of loftier quality even at low resolution if the viewing altitude is great enough.)^[12]

If nosotros regard typographic characters equally images, then the same considerations that we have made for graphics apply fifty-fifty to the composition of written text for printing (typesetting). Older character sets were stored as bitmaps. Therefore, to achieve maximum print quality they had to be used at a given resolution only; these font formats are said to exist not-scalable. High-quality typography is nowadays based on graphic symbol drawings (fonts) which are typically stored as vector graphics, and as such are scalable to any size. Examples of these vector formats for characters are Postscript fonts and TrueType fonts.

Functioning [edit]

Advantages to this style of drawing over raster graphics:

Because vector graphics consist of coordinates with lines/curves between them, the size of representation does not depend on the dimensions of the object. This minimal amount of information translates to a much smaller^{[ citation needed ]} file size compared to large raster images which are defined pixel by pixel. This said, a vector graphic with a small file size is oftentimes said to lack item compared with a existent world photograph.
Correspondingly, one can infinitely zoom in on e.m., a circle arc, and information technology remains smooth. On the other hand, a polygon representing a bend will reveal existence not actually curved.
On zooming in, lines and curves demand not get wider proportionally. Often the width is either not increased or less than proportional. On the other hand, irregular curves represented past uncomplicated geometric shapes may be made proportionally wider when zooming in, to keep them looking smooth and not like these geometric shapes.
The parameters of objects are stored and tin be afterwards modified. This ways that moving, scaling, rotating, filling etc. doesn't dethrone the quality of a drawing. Moreover, it is usual to specify the dimensions in device-independent units, which results in the best possible rasterization on raster devices.
From a three-D perspective, rendering shadows is also much more than realistic with vector graphics, as shadows can exist bathetic into the rays of light from which they are formed. This allows for photorealistic images and renderings.

For instance, consider a circumvolve of radius r.^[13] The principal pieces of information a plan needs in society to draw this circle are

an indication that what is to be drawn is a circle
the radius r
the location of the middle point of the circle
stroke line style and colour (possibly transparent)
fill style and colour (possibly transparent)

Vector formats are not ever appropriate in graphics work and also have numerous disadvantages.^[xiv] For instance, devices such as cameras and scanners produce essentially continuous-tone raster graphics that are impractical to convert into vectors, and so for this blazon of work, an paradigm editor will operate on the pixels rather than on drawing objects divers by mathematical expressions. Comprehensive graphics tools will combine images from vector and raster sources, and may provide editing tools for both, since some parts of an paradigm could come from a photographic camera source, and others could have been fatigued using vector tools.

Some authors have criticized the term vector graphics as being confusing.^[15] ^[16] In item, vector graphics does not only refer to graphics described by Euclidean vectors.^[17] Some authors accept proposed to use object-oriented graphics instead.^[15] ^[eighteen] ^[nineteen] However this term can also be confusing as it can be read as whatsoever kind of graphics implemented using object-oriented programming.^[15]

Vector operations [edit]

Vector graphics editors typically allow translation, rotation, mirroring, stretching, skewing, affine transformations, changing of z-order (loosely, what's in forepart of what) and combination of primitives into more circuitous objects.^{[ citation needed ]} More sophisticated transformations include set operations on closed shapes (union, difference, intersection, etc.).^[20]

Vector graphics are ideal for uncomplicated or composite drawings that need to be device-contained,^[21] or exercise not demand to achieve photograph-realism. For case, the PostScript and PDF folio clarification languages use a vector graphics model.
