As a result, the model has depth and it is easier to interpret the physical events and mechanical interactions. Using a hand-held wand, a researcher can rotate, translate, and zoom the model interactively in real time. The researcher has now entered into semi-immersive virtual reality. Other observers, also wearing goggles, can watch as the three-dimensional model is manipulated. The display can be interactive or, if desired, a sequence can be captured and replayed as an animation.
Researchers can use an interactive wand to zoom in for closeups of their models.
This fan interaction simulation shows the dramatic results of a blade loss. Glenn's physics-based computer simulations were successfully demonstrated on the ImmersaDesk for a large group of visiting representatives from those industry partners. In addition to being useful onsite for such collaborations, the ImmersaDesk is portable and can be shipped offsite for use at conferences and expositions so that NASA visualizations can be presented to a wider audience. This fan interaction model can be viewed in stereo from all angles on the ImmersaDesk while cycling through the time steps of the traumatic blade out event.
