Vectors and Rasters

Vector Graphics (geometric modeling, Object-oriented graphics)

vector images are similar to jpegs and bitmaps but they are different and much more useufull because vector images can be streched and twisted and the stays the same. vector images can also be edited alot more for example. the detail of the images can be removed to make an images for a leaflet or sign.

vector images are different to raster images because they record points on all of the picture just like star constellations and this means that the images can be remembered. they are remembered because of lots of mathematical equations

Raster Images

Raster images are usualy made a very a large group of rectangles called pixels each of these pixels have a colour this makes up the picture and how the picture is colored and looks.

Unlike vector images when raster images are stretched the squares become bigger and because further squares are not added the images becomes very very blocky giving the picture less definition therefore ruinening the picture.

On the other hand raster images are very small in size compaired to vectors so you sacrifice quality for quantity. As you can store more raster images then vectorsthis means raster images are more practical in everyday use than vectors but vectors have better quality overall.

So in summary raster images should be used for everyday purpose and vector images should be used for the specalist jobs like graphic design for websites or concept art for games.
