#### Brief description

This course provides students with an understanding of the theoretical foundations of computer graphics, with an emphasis on analytical skills for graphical object representations.

#### Aims

This module, building on prior learning obtained through the study of module CS32110, will address the topics needed to understand the theoretical foundation of computer graphics, and in particular, the graphical representation of objects. Students are introduced to topics that include:

• The underlying mathematics of 2- and 3-dimensional graphics display techniques
• 2- and 3-dimensional geometric coordinate transforms
• Projection representations
• Solid Modeling
• Representation through curves and surfaces
• Motion capture techniques
