Assesment methods and criteria linked to learning outcomes

  • Project - 18 points.
  • Evaluated laboratory tasks, 6 x 3 bodů - 18 points.
  • Midterm written exam - 12 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.

Exam prerequisites:
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.

Aims

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.

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