COMP3214 Principles and Practice of Computer Graphics

Module Overview

The manipulation and display of geometric information is at the heart of many computer applications and graphical output plays an important part of modern Human - Computer interactions. The aim of this course is to show how to generate, manipulate and display synthetic scenes. The module concentrates on the generation of 3D images in a Computer Games context. The module covers the underlying theory and algorithms, as well as providing opportunity to practice the use of these techniques in an OpenGL Environment. Maths up to basics calculus, matrices and vectors. Programming in C++, using an Object Oriented interface but not necessarily generating them. The module is not about human computer interfaces, windowing systems, specific API's or 3D content creation tools like Blender or Maya 3D.
