A 3D City Model is a 3D representation of a major Australian and New Zealand CBD’s. Each model is painstakingly constructed to a set level of detail using 3D Studio Max and a specialised authorware that produces 3D models from stereo pair data and aerial photography captured using helicopters or light wing aircraft. The resulting 3D model is to real world scale and orientation and each is available in a variety of 3D formats.
