What is Computer Graphics ?

Humans Communicate well with images

1/3 of our brain is devoted to visual processing

A picture is worth a thousand words

• WYSIWYG (What You See Is What You Get) paradigm

Definition : Picture style I/O technology involving the creation manipulation storing and display of pictures with the aid of computer

Numericaldata

Picture (Image)data
