, RASTER SCAN GRAPHICS
• The graphic software involves the conversion of the vectorial
information of the drawing into its equivalent raster format such
that the frame buffer can be filled with that information.
• This process is called rasterization.
• Two common forms of elements present are straight lines, circle
• Algorithms developed for these elements are
i. DDA Algorithm
ii. Bresenhams Algorithm
