Graphics as you know it is what we see on screen it is a way
of illuminating pixels of the screen with different colors that makes a
picture. When it comes to graphics there are 2 types’ vector and raster
Let’s first consider raster graphics
They are graphics that is develop by programs like Photoshop
each pixel information is saved in a file so when displayed it can be mapped to
positions of the screen this is normally fast since it is 1 to 1 mapping from image
pixel values to screen the draw is faster compare to vector but the drawback is
it will pixelate when zoomed i.e. when you enlarge it pixels also get enlarged
and begin to show them as blocks of squares
Next we have the vector graphics
They are mathematical algorithms use to draw geometrical
things like lines, curves ellipse and so on so the values of the variables are
kept in file and when need to display take the values and draw it using and
equation like an equation for line or ellipse this method is slow compare to
raster graphics since the data need to
be processed before any drawing can be made but the benefit of it is you can
zoom it to whatever the level you want,
it will use a translation, rotation or scaling functions of geometry to
calculate the end result. Resulting a smooth translation of the object software like illustrator use this to draw images. also 3D's Max and Maya like 3D animation software and most of the 2D animation software use these as models and Raster graphics as texture to them
