One of the original challenge models for large-scale 3D visualization was this oil-rig. Using new Fraunhofer IGD methods and emerging standards for binary compression, its now running in your web browser!!! Use the web slider to change the time of day and shadows in the 3D model. This models and other large models are listed in the examples below.
