Types of Computer Graphics

Have you ever thought how image is represented in your computer? They are done by Computer Graphics.Computer graphics are graphics created using computers and used in the the representation of image data.Because of Computer Graphics only, you can see videos,play computer games.Computer Graphics is all about displaying images to the user.
Computer Graphics is of two types :
1)Vector Graphics
2)Raster Graphics
Vector Graphics : Vector graphics use mathematical relationships between points, lines, curves, and shapes or polygons to represent images in computer graphics.Vectors are composed of paths.
When zoomed they continue having their aspects because image is based on mathematical formula that govern it's shape.

Any particular vector file format supports only some kinds of primitive objects. Nearly all vector file formats support simple and fast-rendering primitive objects:

Lines, polylines, polygons,Bézier curves, bezigons, Circles and ellipses

Vector file formats:

1)CGM
2)Gerber format (RS-274X)
3)SVG
4)Other 2D vector formats like AI (Adobe Illustrator), CDR (CorelDRAW), DrawingML, GEM metafiles (interpreted and written by the Graphical Environment Manager VDI subsystem), Graphics Layout Engine 5)3D vector formats like AMF - Additive Manufacturing File Format, Asymptote - A language that lifts TeX to 3D., .blend-Blender, COLLADA, .dwf, .dwg, .dxf, .flt - OpenFlight
Raster Graphics: Rater Graphics are made of small rectangular shaped pixels,more the pixels more is clearity of picture.These are also known as Bitmap images.Each pixel contains one or more bits of information, depending on the degree of detail in the image.When zoomed,ttheir resolution decreases.
Black-and-White image: contains only one bit per pixel (a binary bit can be in one of two states; thus, a single bit can represent white or black)
Coloured and shaded picture: commonly contains 24 bits of information per pixel.Thus, an array of pixels of various colors, which together form an image
Images produced from optical scanners,digital cameras,phones are raster graphics and images on the Internet. Modern computer-monitors typically display about 72 to 130 pixels per inch (PPI), and some modern consumer printers can resolve 2400 dots per inch (DPI) or more; determining the most appropriate image resolution for a given printer-resolution can pose difficulties.
Raster file formats are :
3.1 Raster file formats
JPEG/JFIF
JPEG 2000
Exif
TIFF
RAW
GIF
BMP
PNG
PPM, PGM, PBM, and PNM
WEBP
