Open Source
Beside commercial software packages there is also a number of Open Source Projects that support CityGML.
Open Source Projects
libcitygml is a small and easy to use open source C++ library for parsing CityGML files in such a way that data can be easily exploited by 3D rendering applications (geometry data are tesselated and optimized for rendering during parsing). For instance, it can be used to develop readers of CityGML files in many 3D based applications (OpenGL, OpenSceneGraph, ...) |
