The goal of Virtual Terrain Project is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form. This includes a suite of cross-platform, open-source software for all stages of geospatial visualization, integrating GIS and Vis-sim.
VTBuilder: A 2D geoprocessing tool; much like a conventional GIS but with higher-level knowledge for datatypes like transportation networks. It prepares data for visualization.
Enviro: A 3D runtime environment, with the aim to support visualizing any amount of data interactively.
