iWalkthru is a technology for virtual walkthroughs of large 3D environments. It contains a preprocessing
utility that reduces a whole scene and creates an octree based scene database. This database
can be accessed by a normal http server, since all scene information is contained in the database itself.
A viewer application (and a corresponding web browser plugin) reads the scene database (via http) and
renders the scene on the screen.
Only visible parts of the scene have to be transferred to, and stored on, the client, which makes iWalkthru
suitable for applications with restricted network speeds and client memory.
In combination these tools reduce a lot of the issues of delivering complex 3D environments online.
Typical applications that will gain most from using iWalkthru are reconstructions of real-world environments, like:
