Computers and Graphics
FSI-VPGAcad. year: 2020/2021
The course is intended as an introduction to the history of computer graphics, 2D and 3D graphics methods, problematics of colours and colour systems, imaging and image processing, classification of display devices. It gives an overview of text and graphics user interfaces, introduction to desktop publishing, and an overview of print methods and technologies.
Learning outcomes of the course unit
Obtaining a qualified overview and references on contemporary technologies of computer graphics.
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.
Language of instruction
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.
