Course Objective
 This course provides an introduction the basic concepts of
computer graphics.
 While graphics has become widespread, few people understand the
internal workings of applications like video games, Adobe
Photoshop, etc.
Course Objective
 Computer Graphics IT300 is designed to provide students with an
introduction to the fundamental algorithms of computer graphics
through detailed coverage of the mathematics and implementation
of 2D and 3D line, curve and surface drawing.
 The goals of this course will be to:
 Introduce JAVA 2D/3D API, a common graphics programming API
 Discuss a number of important, low level implementation details
hidden by APIs like JAVA 2D/3D
 To understand the basic structures of 2D and 3D graphics systems
 Identify computer graphics related fields.
 To learn problem solving skills.
 Through the course study you will learn a set of powerful
mathematical and computational tools.
What you will NOT learn?
 Software packages
 CAD-CAM
 Photoshop and other painting tools
 Artistic skills
 Game design
 Graphics API
 Although you will be exposed to JAVA 2D/3D
What is Computer Graphics
 In general sense, computer graphics is the process of producing a picture
or Image using computer.
 This includes applications that start form drawing simple graphs or
line drawings
 And ends with programs that involve complex mathematics and
physics in the production of highly accurate images.
 Added to this is the capability to create a series of images that result in
an animation.
 The purpose of this Course is to explore some of the basic ideas of realistic
image generation.
 The goal then is the creation of an image by writing a program instead of
taking a picture with a camera.
Why Computer Graphics
 There is virtually no area in which graphical displays cannot be
used to some advantage and so it is not surprising to find the use of
computer graphics so widespread.
 Today, we find computer graphics used routinely in such diverse
areas as science, engineering, medicine, business, industry,
government, art, entertainment, advertising, education, and
training
