To provide an overview of the basics principles of 2D and 3D computer graphics. To get acquainted with the vector-based object representation and drawing. To learn methods of 2D objects rasterisation and clipping, 2D closed areas filling, 2D and 3D transformations, visibility problem solutions, lighting, shading and texturing. To get acquainted with the basic principles of main 2D and 3D graphical interfaces. To overrule the implementation issues in real graphical applications.

Nowadays computer graphics are everywhere. We meet it daily while watching movies and playing games (3D modelling and rendering) or using graphical user interfaces of different SW applications. This is because the graphical expression is a very effective way of passing information between computer and human.
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.).

• Introduction to Programming Systems (IZP)

   - It is essential to have basic knowledge of programming in C language.

Thematically oriented individual project.

• Project - 20 points.
• Evaluated laboratory tasks, 6 x 3 bodů - 18 points.
• Midterm test - 10 point.
• Final written examination - 52 points.
• Minimum for the final written examination is 20 points.
• Minimum to pass the course according to the ECTS assessment - 50 points.

• The project needs to be submitted to the faculty information system and is evaluated at the end of the semester.
• Laboratory tasks are evaluated during them.
• Midterm and final written exams.
• In justified cases, it is possible to accomplish laboratories on another date, and the mid-term exam by extending the final exam.

The student has to get at least 20 points from the project, laboratories and the midterm exam for receiving the credit and then for entering the exam. Plagiarism will cause that involved students are not classified and disciplinary action can be initiated.
