Entry knowledge

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

Rules for evaluation and completion of the course

  • Project - 20 points.
    • The project needs to be submitted to the faculty information system and is evaluated at the end of the semester.
  • 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.

 

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

Aims

To provide an overview of the basics principles of 2D and 3D computer graphics.

  • The student will get acquainted with the basic principles of 2D and 3D computer graphics - algorithms for rasterisation and clipping of 2D graphics primitives and filling of closed regions; algorithms for 2D and 3D transformations, visibility solution, lighting, shading and texturing.
  • The student will get acquainted with different techniques of 3D objects geometry representation.
  • The student will learn the fundamentals of the photorealistic rendering of 3D scenes.
  • The student will get acquainted with sources of alias and basics of antialiasing methods.
  • The student will learn the fundamentals of using main graphical programming interfaces and will practice implementation of vector and raster based graphics algorithms.
