70090 - Computer Graphics

Learning outcomes

At the end of the course, the student will have the basic elements of computer graphics in order to use competently major commercial software to create graphical user interfaces through the use of OpenGL libraries for modeling of free-form curves and surfaces, the creation of interactive tools for the manipulation and rendering of 3D objects.
