Computer
graphics is a very appealing
field of study. You learn to write programs that create pictures, rather than
streams of text or numbers. Humans respond readily to pictorial information,
and are able to absorb much more information from pictures than from a
collection of numbers. Our eye-brain systems are highly attuned to recognizing visual
patterns. Reading text is of course one form of pattern recognition: we
instantly recognize character shapes, form them into words, and interpret their
meaning. But we are even more acute when glancing at a picture. What might be
an inscrutable blather of numbers when presented as text becomes an instantly
recognizable shape or pattern when presented graphically. The amount of
information in a picture can be enormous. We not only recognize what’s “in it”,
but also glean a world of information from its subtle details and texture.
As Compare to earlier editions (1st and
2nd) the authors made some additions in third edition. They add some new
advance concepts and new exercise materials also. This books helps you to learn
basics as well as advance concepts of Computer Graphics using 2D and 3D
methods. The most cool thing in this book is the case studies which are
included at the end of each chapter. I am going to mention its contents right
here that will definitely helps you before reading this book.
