Learning Outcomes

On successful completion of this module students should be able to:

Select and deploy appropriate algorithms, programming languages and libraries behind 3D computer graphics and games.

Describe and apply the main concepts behind 3 dimensional graphics and games software libraries.

Demonstrate an awareness of the variety of hardware and software technologies that allow the creation of graphics and games applications.

Use vectors and matrices to perform 3-D transformations, including perspective and orthographic projections.

Describe and critique different lighting models and rendering techniques.

Describe and critique alogrithms for modeling a variety of objects/visial phenomena.

Describe and critique the main elements of a 3D games engine, including collisions, physics states and AI.

Aims

This module provides the basis for programming 3D computer graphics and games. Theoretical concepts are introduced and how they are translated into real-time, interactive applications.

Brief description

This module provides students with an understanding of the theoretical foundations of computer graphics, game development concepts and practical 3D graphics and games programming skills.
