Brief description

This course provides students with an understanding of the theoretical foundations of computer graphics and practical 3D graphics programming skills

Aims

This module provides the basis for computer graphics, allowing students to start work in the area of computer graphics. Students are introduced to topics that include:
  • The underlying mathematics of 3-dimensional graphics modeling and display techniques
  • 3-dimensional geometric coordinate transformations.
  • Lighting models including local and global illumination techniques
  • Interactive graphics programming
