Course detail

Modern Computer Graphics

FEKT-MKC-MPGAcad. year: 2020/2021

The course deals with computer graphics and 3D modelling. The objective is to introduce computer modelling of a scene both from the theoretical and the practical sides. Topics cover a wide range, beginning with colour models, through the theory of polynomial 3D modelling, up to the implementation, including exploiting the possibilities of the GPU.

Learning outcomes of the course unit

Via the lectures, students get to know the theory of computer graphics, while exercises run on computers slead to a practical experience --- mainly implementing 2D and 3D models using the OpenGL library.

Prerequisites

The subject knowledge on the Bachelor degree level (in Teleinformatics) is required. Knowledge of signal processing is of advantage.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods include lectures and computer laboratories. The course is taking advantage of e-learning (Moodle) system. Students have to work out an individual computer graphics project during the course.

Assesment methods and criteria linked to learning outcomes

Individual project: 25 points
Tests: 12 points
Tasks in exercises: 3 points
Main exam: 60 points, minimum 20

Course curriculum

1. Colour models and colour spaces. Representation of images in the computer: number formats, memory organization, video modes.
