Description:

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.

Contents:

1. Introduction to computer graphics. Writing shaders in OpenGL I ? fundamentals.
2. Writing shaders in OpenGL II ? data & buffers. Introduction to GLUT.
3. Transformations I (coordinate systems, model, view).
4. Transformations II (projection, viewport, gimbal lock).
5. Light and color, illumination and shading models, light and materials in OpenGL.
6. Textures and texturing (texture mapping and filtering).
