High Quality Content by WIKIPEDIA articles! CityEngine, is a 3D modeling application specialized in the generation of three dimensional urban environments. With the procedural modeling approach, CityEngine enables the efficient creation of detailed large-scale 3D city models with merely a few clicks of the mouse instead of the time exhaustive work intensive method of object creation manual placement. CityEngine works with architectural object placement arrangement in the same manner that VUE manages terrain, ecosystems atmosphere mapping is equally as diverse in its ability of object manipulation environmantal conformity/harmony as its VUE counterpart. CityEngine can in fact even be used inside of the e-on software VUE program to complete the ultimate in real world CGI/3D generated scenes effects... at a surprisingly affordable price in comparison to many of the top/leading 3D programs on the current market.
