Computer Graphics

Course Objectives

At the end of the course, students will

• have a good understanding of the role and importance of 2-D graphics in computer systems,
• understand the mathematics underlying objects transformations and clipping operations,
• be familiar to 3-D graphic concepts,
• be familiar to surface rendering and aware of the techniques which can be used,
• be able to produce photo-realistic rendering,
• be able to draw simple objects using C/C++, and to model more complex objects using simple primitives, and
• create simple animations.

Course Description

Introduction (applications of computer graphics, Graphical User Interfaces, graphical input devices, graphical display devices, software standards, Open GL, GKS, PHIGS); simple drawing algorithms (line drawing and attributes, polygon drawing, circle drawing, ellipse drawing, character generation and attributes); transformations and clipping (basic transformations, translation, scaling, rotation, clipping algorithms); Windows and Viewports (co-ordinates representation, Viewing Pipeline, Window to Viewport transformation, zooming and panning effects with windows and viewports); 3-D Graphics (3-D Geometry, 3-D transformation, display methods, parallel projection, perspective projection, depth cueing, 3-D object representation, The Virtual Camera, modeling concepts); surface rendering.
