I just ran across an interesting software tool that promises real-time visualization tools to explore development alternatives. The software imports GIS, CAD and Google Sketchup data to view design alternatives.
OrbisRT debuted at the ACADIA 2007 Conference. It’s a visualization/game engine that’s being built by the Centre for Landscape Research (University of Toronto), ICDVM (University of Waterloo), and Immersion Studios.
I’m particularly impressed that it’s designed on OpenGL and OpenSceneGraph and is planned to be released as free and Open Source software.
