The teaching subject is a composition of the basic virtual studio and virtual reality techniques, which are based on computer graphics or tracking.
A virtual studio serves the tools to produce multimedia contents for any kind of field of applications, that base on video engineering, e.g. TV, movies and webcastings. Picture components from records are extracted to be pasted into computer designed scenes - this happens by estimating the scene parameters to the pasted objects.
Virtual reality (artificial created reality) is a computer-only production-method.
Computer-generated objecs can be persons and objects, hybrids of both or complex designed backgrounds. This objects are placed into an so called virtual environment.
Virtual reality is realized via perceptions in virtual environments. Those environment are computer-supported systems, that benefit from the visual, acoustic, haptic and olfactory senses of the human nature to convey the user experience.
