For 3-D Modeling we use a program called FormZ. You can check out their web site at www.formz.com. It is specifically designed as a modeler, which is a program that builds objects and settings in the 3-D digital world. It also has a built-in renderer, which allows us to control lighting and reflections. You can see some of our models on the samples page here.
One of the features of FormZ is the ability to create panoramic views, fly-throughs or Quicktime VR movies. Here are some samples of our work with 3-D modeling and massing:
Wireframe fly-by of homes located behind a hill
VR of a water tank stealth cell site
Walk-through of a conceptual pedestrian bridge for the American River
