The course deals with a topic of 3D modelling and its use for virtual and augmented realities. Introduces modelling of 3D objects, capturing 3D objects and visualization of 3D objects. Basic principles of virtual and augmented realities are discussed, as well. Specific camera systems for capturing 3D objects and 3D scenes are analysed, too. Special complex systems and applications for experience-based videoconferencing based on virtual teleport are presented at the end of this document.
