Course detail

Computers and Graphics

FSI-VPG-AAcad. year: 2019/2020

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.
