Computer Graphics Lecture 01 Fasih ur Rehman

About Instructor MSc in Electronics and MSc in Systems Engineering in 1994 and 1996 respectively from Quaid-e-Azam University and currently pursuing PhD from CIIT Worked for Software Industry (developing engineering application) for 5+ years in Pakistan and abroad as well. Joined CIIT Wah Campus in 2003 as Assistant Professor and worked at various academic and administrative positions since then Research Interests Mathematical Modeling, Computational Electromagnetics

Today’s Agenda Introduction to the Course

Course Contents Overview of Computer Graphics; Uses of Computer Graphics in various fields. Drawing Elementary Figures. Two dimensional Geometric Transformations and viewing; Three dimensional Transformations and modeling. Graphical User Interfaces (GUI)

Recommended Books Introduction to COMPUTER GRAPHICS by Anirban Mukhopadhyay, Arup Chattopadhyay Fundamentals of Computer Graphics Third Edition by Peter Shirley and Steve Marschner

Learning Outcome After successful completion a student should be able to – identify various application areas of the graphics – define basic terminology of computer graphics – differentiate various graphic areas – characterize output and input devices for their effective use in the area – understand and use various transformations – construct elementary shapes on computer – generate 3-D models on computer

A phrase “A picture is worth a thousand words” “A picture paints a thousand words” Chinese version is “One picture is worth ten thousand words”

What are Computer Graphics The study of using computers to create and manipulate images is called Computer Graphics In true sense the subject requires rigorous background in Linear Algebra especially Matrices.

AREAS

Graphics Areas The area of Computer graphics that deals with the mathematical specification of shape and appearance properties in a way that can be stored on the computer is called Modeling. The creation of shaded images from 3D computer models is called Rendering. Modeling of interaction of light with matter is called Illumination. The technique to create an illusion of motion through sequences of images is referred to as Animation.

Why Computer Graphics With emergence of usage of computers in almost every wake of life, the area of Computer Graphics has earned huge importance because of its utility and simplicity.
