Course Description

Computer graphics and visualisation applications range from art and entertainment to science and engineering, biology, and medicine. This course prepares students for work in complex modelling and application development fields. It covers the fundamental principles, concepts, and algorithms of computer graphics and visualisation. Students will learn mathematical and computational techniques for modelling, representing, and displaying geometric objects, as well as how to use these techniques for data visualisation. 

Course Objectives 

To introduce the use of a graphics system and become familiar with building approach of graphics system components and algorithms related with them. Also covers the basic principles of 2D and 3D graphics. And an understanding of how to scan convert the basic geometrical primitives, how to transform the shapes to fit them as per the picture definition.
