I´m trying to read and construct roof-geometry from a citygml file. Converting the walls and the floors of the buildings into proper geometry is simple but I´m struggling with the roof structure which is not always planar and can be concave or convex. I´m also wondering why my approach takes some time to process. I mean the data is “just” a conversion of points?!
I`m looking for a fast and robust way to convert all the geometry in (closed) breps. Thanks!
Note: I´m using jSwan-Plugin to convert the xml to json first and then navigating to the data. Other methods/plugins are welcome as well. The data is quiet large so it might take few seconds to read it.
I´m looking for a “grasshopper-approach”. Therefore approaches using AntFarm or FZK-Viewer are not what I`m looking for. Thanks in advance!
