Is it possible to create multiple roof types, or detect complex roof shapes using 3Dbag data? #34

What I mean is that it's ok to generate buildings with flat or non flat roofs (simple roof shape) using a mean height.

But what about if the roof type is gable and other types, what do you think would be the best way to do that? What I mean essentially is how to generate a 3d model as close to reality as possible?

Greetings!

No, and that's a research field on its own. This bag3d tool itself doesn't do any 3d reconstruction, but manages the instructions for running 3dfier. If you have an executable that can create more complex roof types, then its possible to replace 3dfier. However if the requirements/input of such an executable are very different from 3dfier's, then you'll likely end up building a new software.

Thank you for your reply. That's what I'm figuring out. Did you see the new Microsoft flight simulator technology? Seems quiet interesting..

I can't tell much about what I'm doing but I can say that the 3Dbag services are really good for us. I think that 3dfier does a great job, so there's no point to try to replace it. But thanks to the raw nature of json data there are other purposes possible.

That's the strength of the wfs geoservice from 3dbag, that people can do what they want with the data. it would not be the same with 3dfier.
