A simple 3D viewer to visualize the results generated by ePLU building generator Dependencies: boost_system,boost_filesystem,OpenSceneGraph The viewer provide two functions: 1) visualize final results of multiple experiments which are stored in folder .../bldgs_final Please make sure the parcel data named "parcelle.shp" is also in the same directory 2) visualize evolution (intermediate results) of one experiment which is stored in a txt file, e.g. .../bldgs/bldgs_exp9.txt Please make sure the parcel data named "parcelle.shp" is also in the same directory Manipulation: use left mouse button to translate and rotate the scene use right mouse button or mouse scroll to zoom in/out use up and down arrow keys to navigate different building layouts Acknowledgments This research is supported by the French National Mapping Agency (IGN) It is partially funded by the FUI TerraMagna project and by Île-de-France Région in the context of e-PLU projet
