Vector graphics

RASTOR GRAPHICS

- Use of polygons to represent images in computer graphics

-Based on vectors ( control point or nodes)

-Definite position on the X- and Y- axes

-Including such values as stroke color, shape, curve, thinckness and fill

RASTOR GRAPHICS

-a way to painting a image line by line

-Most modern computers have bit mapped displays

Vector graphics

-GIF, JPEG, and PNG, which are popular on the World Wide Web.

-employed in video games and are also used in medical imaging such as MRI scanners.

- The first uses of vector graphic displays was the US SAGE air defense system

-1999: Vector graphics systems were retired from US air traffic control

- Likely still in use in military an specialized systems

- Vector graphics were also use on the TX-2 at the MIT (Massachusetts Institute of Technology) Lincoln laboratory by computer graphics pioneer Ivan Sutherland to run his program sketchpad in 1963

VECTOR VS RASTOR

RASTOR GRAPHICS

- Engineering drawings are typically printed as bitmaps after VECTOR to RASTER conversion

-"Vector graphics" is mainly used today in the context of 2D computer graphics

-Raster display

-Text / multimedia / 3D rendering

- All modern 3D rendering is done using extension of 2D VECTOR graphics techniques

-Painter, Photoshop, Paint.NET, MS Paint, and GIMP, revolve around editing pixels,

- unlike vector-based image editors, such as Xfig, CorelDRAW, Adobe Illustrator, or Inkscape,

Vector graphics

RASTOR

VECTOR

-The World Wide Web Consortum (W3C)

-Scrable Vector Graphics (SVG)

-Scrable Vector Graphics Tinny (SVGT)

-Bitmaps/ pixel arrays

RASTOR GRAPHICS

Vector graphics

-geographic data in the pixel values as well as the pixel locations.

-72 to 130 pixels per inch (PPI),

-2400 dots per inch (DPI)

-The size of representation does not depend on the dimensions of the object

- Rastor can't be vector

Vector graphics

RASTOR GRAPHICS

Three dimensions

- Digital art is an artistic work or practice that uses digital technology as an essential part of the creative or presentation process
