vrNav2 Description

vrNav2 is an easy-to-use 3D scene navigation program for viewing 3D models in a virtual reality environment. Additionally, Collaborative VR allows two communicating vrNav2 instances, both running on the same model, to communicate and work together. vrNav2 is built on top of OpenSceneGraph (OSG) and vrJuggler. It allows you to load models in any of the data formats that OSG supports. The properties of the models and the navigation are configurable both via a model config file and by arguments to the program. Spherical (multiple viewing frustum), spherical stereo, flat plane (single viewing frustum), flat plane stereo and any size tiled display are configurable via base and display config files. A set of these config files come with vrNav2 and you can easily modify them for your particular display configuration. The scripts that come with vrNav2, and which start it up, automatically select the appropriate config files according to the way the system is set up. vrNav2 has been configured to work with both architectural models and models created as part of scientific visualizations. vrNav2 supports multiple time steps for the scientific models and multiple switches and date switches for the architectural models. The mouse and keyboard are used for navigation and control. In addition, a remote GUI, written in Java, can be run on any machine, the one running vrNav2 or another machine. This GUI can connect to a running vrNav2 in order to control it. The vrNav2 GUI provides many of the same control features as the keyboard does. It also provides controls not available via the keyboard. vrNav2 allows you to make movies on the fly by saving a numerical sequence of images that you can later paste up into a movie. It can save left and right eye image sequences when run in stereo mode. These images can later be transfered into either an active stereo movie or a red/ blue stereo movie. As you navigate around the virtual world vrNav2 can save segment(s) of your flight path or key frames along your flight path. Subsequently it can navigate through the virtual world on either the path you saved or a path it creates via spline interpolation of the key frames. In vrNav2 pre-defined flight paths are often created and then flown in conjunction with saving the frames for movie creation.
