This Course Unit introduces students to the theory and practice of Interactive Computer Graphics. Its principal aim is to teach the fundamental principles of two- and three-dimensional Interactive Computer Graphics. OpenGL is used as the platform for practical C programming exercises, and as an example of a system which incorporates many of the fundamental ideas and algorithms of modern computer graphics.

Learning Outcomes

A student completing this course unit should:

Have a knowledge and understanding of the structure of an interactive computer graphics system, and the separation of system components. (A)
Have a knowledge and understanding of geometrical transformations and 3D viewing. (A)
Be able to create interactive graphics applications. (B)
To use OpenGL to perform item (3), above. (C)
Have a knowledge and understanding of techniques for representing 3D geometrical objects. (A)
Have a knowledge and understanding of interaction techniques. (A)
Have a knowledge and understanding of the fundamental principles of local and global illumination models. (A)

Assessment of Learning outcomes

Outcomes 5 and 7 are assessed by examination. Outcomes 1, 2, and 6 are assessed by examination and in the laboratory. Outcomes 3 and 4 are assessed in the laboratory.
