In 2006, a mysterious 900x700m solid terrain model with military facilities was discovered by a German Google Earth user next to the Chinese town of Huangyangtan. It was quickly identified as a 1:500 replica of a disputed area in Tibet between China and India 2400km away, with perfectly matching orientation. Chinese authorities claimed the model was built 7-8 years earlier as a tank training facility. It is unclear […]
A real case study involving the use of a physical 3D trajectory visualization on top of a 3D terrain model to analyze the causes of a plane crash. This case study is interesting in terms of cost-benefit analysis, since these models appear to be extremely time-consuming to build. The case study includes an informal comparison with animations: "The mock jurors later related that the physical model […]
The XenoVision Mark III Dynamic Sand Table by the company Xenotran is a self-reconfigurable solid terrain model with military applications. There is little information on this device but it seems well ahead of its time. Michael Schmitz and coauthors explain how this high-resolution shape display with 7000 actuators was originally inspired by a scene from the X-Men movie (see our entry 2000 – A Shape […]
The PARM system is part of an ongoing research project at the University of Nottingham. A static physical relief model is augmented with top projection to display landscape details and to overlay with additional data visualizations. Sources: James Goulding's project page.
