COMP3080 - Computer Graphics

Note: Whilst every effort is made to keep the syllabus and assessment records correct, the precise details must be checked with the lecturer(s).

Code COMP3080 (Also taught as: COMPGV10)
Year 3
Prerequisites Successful completion of year 1 and 2 of the Computer Science programme
Term 1
Taught By Anthony Steed (100%)
Aims To introduce the fundamental concepts of 3D computer graphics and give the students all the knowledge needed for creating an image of a virtual world from first principles.
Learning Outcomes The students will be able to define a virtual world and create images of it. They will know how to write a basic ray tracer, and use a graphics library such as OpenGl (or equivalent).

Creating an image using ray tracing

Ray casting using a simple camera

Local illumination

Global illumination with recursive ray tracing

Specifying a general camera

World / image coordinates

Creation of an arbitrary camera

Ray tracing with an arbitrary camera

Constructing a scene

Method of Instruction:

Lecture presentations and lab classes.There are 2 courseworks, equally weighted.


The course has the following assessment components:

  • Written Examination (2.5 hours, 75%)
  • Coursework Section (2 pieces, 25%)

To pass this course, students must:

  • Obtain an overall pass mark of 40% for all sections combined
