or equivalent (authorised by the Director of Studies) Aims: The primary aims are to understand the ways of representing, rendering and displaying pictures of three-dimensional objects (in particular). In order to achieve this it will be necessary to understand the underlying mathematics and computer techniques.
Learning Outcomes:
1. To be able to distinguish modelling from rendering.
2. To be able to describe the relevant components of Euclidean and projective geometry and their relationships to matrix algebra formulations.
3. To know the difference between solid and surface-modelling and be able to describe typical computer representations of each.
4. To be able to explain in detail rendering for raster displays, including lighting models and non-photorealistic rendering.
Application of Number (T).
Classical Modelling: Mesh models and their representation. Constructive solid geometry (CSG) and its representation. Classical Rendering: Raster images; Illumination models; scan line rendering or mesh models an hidden surface removal; ray trace rendering of CSG models; radiosity rendering. Geometry: Projective geometry and homogenous transformations. Colour: colour spaces, limits of the human eye and of display devices; trade-off techniques for screen display and for printing. Modern techniques: Non-photorealistic rendering; image-based rendering; tone mapping; Applications: Animation; parallel rendering; virtual reality and games.
