Computer Graphics and Animation

Course code: AT70.09
Credits: 3(3–0)
This course is elective

Course objectives

To introduce computer graphics as a practical discipline. The underlying theory of computer graphics, as well as implementation algorithms, will be presented in the context of a modern industry-standard graphics programming language and interface. Instruction shall be in a laboratory setting with continuous hands-on implementation of concepts and emphasis on creating animated and interactive scenes.

Learning outcome

Introduction to Computer Graphics. OpenGL Application Programmer Interface. Curve and Surface Modeling. Animation. Interaction. Viewing and Projection Transformations. Color. Illumination and Shading. Texturing. Rendering Algorithms: Scan Conversion, Clipping and Hidden-Surface Removal.


Basic knowledge of two- and three-dimensional co-ordinate geometry and trigonometry and C/C++.
