The biggest obstacle has been the missing of a commonly accepted standards with contemporary technology which also has an adequate distribution. Through the establishment of WebGL in HTML5, a non-proprietary 3D standard is introduced that can be used without any plugins in any modern browser.

With the liberalization of their license conditions and the integration of WebGL/html5 Unity3D was becoming a very interesting tool. Unity is actually a game engine, a development environment for games. Through it´s possibilities two write own code and scripts and then export the application for different devices (PC, Mac, web, consoles, mobile) the possibilities are virtually unlimited. Also Unity is not a web service, therefore you have full control over the created application.

This is a simple example of the possibilities of interactivity 3D Models.
