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. The amount of pages that have been written about this topic in specialized graphics books and technical conference papers is considerable. A book of this size, therefore, cannot expect to give all of the details for the simulation of all the possible natural phenomena that can be included in an image. Rather, the intent of this book is to introduce those concepts that are critical components of realistic image generation or are the foundation on which current efforts are built.

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
