Aims

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.

Contribution to Programme Learning Outcomes

A1, A2, A5, B1, B2, C5, D5.

Introduction to the rendering process with OpenGL (1)


The role of OpenGL in the reference model; coordinate systems; viewing using a synthetic camera; output primitives and attributes.

Geometrical transformations (3)


3D transformations; matrix representation; homogeneous coordinates; combination of transformations.

Interaction (1)


Events and callbacks; input in GLUT

Representing 3D objects (1)


Modelling using polygons; techniques for creating representational polygonal meshes; non-polygonal representations.

Curves and Surfaces (2)


Bezier representations; quadrics and superquadrics; patches and meshes.

Images (2)


Colour in Computer graphics; RGB; CIE; Image formats and their applications: GIF, JPG, PNG.

Viewing (2)


Using the camera model for viewing 3D scenes; perspective and other types of projection; viewing in OpenGL.

A local illumination model (5)


Types of light source; reflectance models: diffuse (Lambert) and specular (Phong); Gouraud and Phong interpolation; lighting and shading in OpenGL; textures.

Application modelling (2)


Distinction between modelling and graphics; immediate mode versus retained mode; model storage strategies; the matrix stacks; OpenGL display lists: traversal; hierarchical data storage; instancing; how the concepts are realised in specific systems: OpenGL, VRML, Java3D.
