In our work, we propose our application of 3D graphics inside the web browser. Nowadays, internet and web browsers are not only space, where user can read information, but it is space also for collaboration and experience. Therefore we propose new ideas how should browsing a modem web page look like with use of state-of-the-art technology and possibilities. Users expect from the displayed application more interesting features, not only display of static text. Standard layout of a web page is based on list of a newspaper or a book. This layout is obsolete and does not fit modem approach in new technologies. Our method of displaying content and information inside the web browser is with full 3D, not only embedding 3D as a special feature inside a small part of web page. In this article we also include virtual Theatre as a case study for this problem and explain possibilities of information display and reasons why is 3D better than 2D in this case.
