Course ObjectiveCourse 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 ObjectiveCourse 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?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 GraphicsWhat 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 GraphicsWhy 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
