Anotation:

Various applications use graphical libraries for the rendering of three-dimensional scenes. The main goal of this course is to introduce students to the Application Programming Interface (API) for 3D graphics and teach them how to program simple interactive OpenGL-based 3D graphical applications. Naturally, the course describes the fundamentals of computer graphics, such as rendering pipeline, geometric transformations, texturing, scene modeling, shading and illumination models, etc. Lectures also cover advanced modeling techniques (parametric curves and surfaces) and selected topics related to scientific visualization. Practices focus on the work on assigned tasks and individual projects to provide students with practical experience with the OpenGL graphics library.

Study targets:

You will know how to program a simple interactive 3D graphical application like a computer game or scientific visualization. You will learn to design the scene, add textures imitating geometric details and materials (like wall surface, wood, sky), and set up the lighting. At the same time, you will understand the fundamental principles and terms used in computer graphics, such as graphical pipeline, geometric transformations, lighting model, etc. You will gain knowledge that allows orientation in the field of computer graphics and represents solid fundamentals for your professional development, e.g., for GPU programming and animations.

Course outlines:
