One way to provide representations for documentation purposes is the generation of digital 3D models. These models provide an intuitive means for scientists not present at the site to examine the model. By using an interactive viewer the user is not restricted to the photographer’s point of view, but can freely navigate in the scene. In addition to that, the models may provide a comprehensive overview of the complete scene. Finally, models that have absolute scale allow distance measuring even after the scene has been destroyed or changed. Other fields of application may be presentations, for example in museums.
