We are glad you are looking at iTowns for geospatial visualization!
A nice use case with Montréal 3D textured models would surely be great to add in our future demos page :)
Concerning your questions on vector tiles, we didn't start working on it in iTowns2 yet. For the moment we just played with vectors coming out of kml files or gpx. The branch for that, not yet integrated (but very close to), is WFS2_rebased.
For vector tiles it might not be that easy to implement as we would need unified data structures and services designed to progressively erase the boundary between vector and raster approaches but we try to provide generic model and graphic generalization patterns to be adaptable to a wide set of geographical objects.
Clearly it would be a nice feature to handle vector tiles in itowns2, if we look at mapbox for example, results are pretty good so any code/advices to work on that in iTowns2 are welcome :)

We are eagerly waiting for the release of itowns v2. Il will be really
useful to have access to a great open source library to display 3D
geospatial data at a very fine level of granularity.
The city of Montréal released a high quality dataset of textured 3D
building. We would like to contribute a public use case for itowns2 with
Some recent work with vector tiles shows us that we could get really
interesting results with this technology. We think that this could be
really useful to display vector data using vector tiles in itowns. In our
use case, we would use vector data as background instead of WM(T)S .
Is there a Provider that can be used to display vector tiles in itowns2?
If there is no direct support for vector tiles, which options are available
to display vector data in other format?
I see that there is KML Provider, but I'm not sure in which branch it is
