Aims

Basic aTo 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.

Specification of controlled education, way of implementation and compensation for absences

  • 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.
  • Injustified cases, it is possible to accomplish laboratories on another date, and the mid-term exam by extending the final exam.
