Learning outcomes of the course unit

Obtaining a qualified overview and references on contemporary technologies of computer graphics.

Prerequisites

General knowledge of contemporary computer hardware, mathematic apparatus of analytical geometry.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

The graded course-unit credit awarding is based on then quality of presentation of search on actual state of the technology, related to given chapter of the course.

Aims

The aim of the course "Computers and Graphics" is to provide students with a complex overview of and references on current technologies of computer graphics, as needed for mechanical and IT engineers.

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

Participation in the exercises is checked by presentation of individual search on problems related to a given topic of the course.
