I have received some photo-realistic building multipatches. The aim is to create an "As-is" model of the entire city as a sort of 3D basemap, so the format should be able to handle huge datasets. I then want to serve the "3D basemap" from ArcGlobe as a GlobeService.
Question #1: Should I convert the multipatches to KML? Which 3D format handles a large number of features the best?
