Why is the course taught
Whether you are going to do computer graphics professionally, or you would just need to 'draw something', it's important to understand basic principles and methods of computer graphics from the perspective of the programmer.
Yes, there are many high-level graphical libraries, however, without this basic knowledge, you can not work effectively with them.
The lectures are dedicated to the theoretical aspects of 2D and 3D graphics principles and algorithms (how it works, what are the problems, how to solve them, etc.) and the laboratories together with the project are dedicated to the practical implementation of the algorithms and methods (how to do it, how to implement it in your code, etc.).
Prerequisite kwnowledge and skills
