Code COMPGV10 (Also taught as: COMP3080 Computer Graphics)
Year MSc
Prerequisites
Term 1
Taught By Tobias Ritschel (66%) and Anthony Steed (33%)
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).
