I really need some help here. So I am trying to create a 3d city of Culver City in CA using City Engine. I would like to have it be as realistic as possible so I want the building roof angles and slopes included in the model. I was think of using Lidar data but wasn't sure if that would be the easiest and most efficient way. Does anyone have any ideas on how I could generate that data? Any thoughts would be appreciated! Thanks!
