IndoorGML2LCC

Processing IndoorGML as a Linear Cell Complex (LCC) class of CGAL

This project contains C++ code that generates a plugin dedicated to the Linear Cell Complex (LCC) demo of CGAL. allows to import an IndoorGML files, convert its goemetry and topology into LCC (CellSpace elements becomes 3-cells, connected 3-cells are 3-sewn through their shared faces, etc). Furthermore, it can generate a simple Node Relation Graph (NRG), as described in the IndoorGML standard and export IndoorGML files that include the newly generated NRG layers. The plugin is directly connected to the viewer of the LCC demo so that the IndoorGML can be visualized.

2. Get the Linear Cell Complex demo from this repository (not yet in the official repository of CGAL).
3. Put all the files of this project in the folder (e.g. IndoorGML2LCC) and put that folder in the Plugins folder of the demo.
4. Compile the CMakeLists.txt of the demo
5. That's it. You should find the IndoorGML2LCC plugin button on the GUI of the LCC demo.
