This course focuses on 2D and 3D interactive and non-interactive graphics. This course studies the principles underlying the generation and display of 2D and 3D computer graphics. In this course topics include geometric modeling, 3D viewing and projection, lighting and shading, color, and the use of one or more technologies and packages such as OpenGL, and Blender. Course requirements usually include exam and several programming or written homework assignments.


  1. To provide a comprehensive introduction to computer graphics leading to the ability to understand contemporary terminology, progress, issues, and trends.
  2. To understand computer graphics techniques (2-D/3-D), focusing on 3D modelling, image synthesis, and rendering.
  3. Introduce geometric transformations, geometric algorithms, software systems (OpenGL), 3D object models (surface, volume and implicit), visible surface algorithms, image synthesis, shading and mapping, ray tracing,  radiosity,  global illumination, photon mapping, and anti-aliasing.
  4. To explore the interdisciplinary nature of computer graphics which is emphasized in the wide variety of examples and applications.


  1. To develop a facility with the relevant mathematics of computer graphics, e.g., 3D rotations using both vector algebra, geometrical transformations and projections using homogeneous co-ordinations.
  2. Apply principles and techniques of computer graphics, e.g., the graphics pipeline, and Bresenham algorithm for speedy line and circle generation.
  3. Apply computer graphics concepts in the development of computer games, information visualization, and business applications.
