Web3D is a set of different technologies that allows a viewer to explore web content in three dimensions. They make it possible not only to navigate in 3D worlds, but also to interact with these worlds.

Web3D is an excellent instrument for commerce. You may show appealing, three-dimensional images of products and then sell them online. Furthermore, panorama technology is finding its way into real estate business. In data presentation, adding an extra dimension to twodimensional datagrams can contribute to a better understanding of data dynamics.

Another broad field of Web3D application is education. Web3D is ideal for education as it allows students to study realistic images of phenomena and objects and then ask questions to the teacher on line by means of multiuser worlds and 3D chats. For example, in science, visualising phenomena such as the movement of astronomical bodies may help students learn. In vocational training, 3D virtual manuals are superior as the student can see tools and objects from every angle. Other conceivable areas where Web3D can be applied are virtual manuals for education or office staff.

There are different technologies that make the vast variety of Web3D application areas possible. Some of them are proprietary, and some are open source. Depending on the business requirements and complexity of 3D content a client may chose one that suits his needs the best. Here we will present some of the open source standards as well as our demo worlds that use these technologies.
