Course detail

Modern Computer Graphics

FEKT-MKC-MPGAcad. year: 2023/2024

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. The 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.

Aims

Students learn about 3D modelling, from the very definition of objects to the implementation at graphic processors. Students utilize the OpenGL to model and process 3D scenes.
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.
