Unique Paper Code: Update Awaited

This course introduces fundamental concepts of Computer Graphics with focus on modelling, rendering and interaction aspects of computer graphics. The course emphasizes the basic principles needed to design, use and understand computer graphics system.

Learning Outcomes:

At the end of the course, students should be able to:

  • Describe Standard raster and vector scan devices as well as Graphical Input and output devices.
  • Implement algorithms for drawing basic primitives such as linecircle and ellipse.
  • Implement algorithms for line clipping and polygon clipping and filling.
  • Implement a 3D object representation scheme and carryout 2D and 3D Transformation, 3D projections.
  • Implement visible surface determination algorithms, Illumination models and surface rendering methods, color models.
  • Implement a simple computer animation algorithm.
