BSc Computer Science (Human Computer Interaction) with Industrial Experience

Year of entry: 2021

Course unit details:
Advanced Computer Graphics

Unit code COMP37111
Credit rating 10
Unit level Level 3
Teaching period(s) Semester 1
Offered by Department of Computer Science
Available as a free choice unit? Yes


This course follows on from COMP27112, the 2nd year course "Computer Graphics, and Image Processing", and looks at more advanced topics in Computer Graphics, such as large-scale polygonal modelling techniques, capturing geometry from scanners and cameras, procedural modelling, and sophisticated global and real-time rendering techniques. The course is supported by a 10-week laboratory project in OpenGL.


Unit title Unit code Requirement type Description
Introduction to Visual Computing COMP27112 Pre-Requisite Compulsory
Students who are not from the School of Computer Science must have permission from both Computer Science and their home School to enrol.


This Course Unit covers the principles of modern techniques for Computer Graphics modelling and image synthesis, on the assumption that students have already completed the introductory Computer Graphics course (COMP27112). Its principal aim is to introduce students to the ever-expanding repertoire of techniques for defining and rendering images of 3D model data. Particular attention is focussed on the increasing requirements for complex rendering and interaction to occur in real-time.

Learning outcomes

  • be able to analyse requirements of 3D modelling problems and select appropriate combinations of modelling techniques

  • be able to describe and compare CAD, Generative and Captured approaches to creating 3D models with respect to their fidelity and time/space constraints

  • be able to describe how the rendering equation acts as a mathematical representation of illumination in the real world

  • be able to compare different computational approximations to the rendering equation with respect to their visual fidelity and computational complexity

  • be able to analyse rendering problems to create novel solutions by combining or modifying existing computational approximations
