Displaying large amounts of extruded polygons on 3d tiles

3D Tiles
1

I have a visualization where I use Google’s 3D tiles and visualize about 20k polygons with extrusions on them. Currently it works fine on desktop, but specifically on iPhone it has issues. I don’t know if it’s due to a possible webgl bug I raised earlier, but on iPhone specifically it regularly crashes. I suspect memory problems, but then again on android it loads just file.

This is the site: Документи за градоустройство, строежи и ремонти

On other projects I used Mapbox with vector tiles, which was great. I understand this is not supported here. Do you have any suggestions how I can do this with the photorealistic tiles and overlay extruded polygons? I though of converting them to 3d tiles, but I don’t have experience with that. Which tool/lib can I use to do that?

Just to have the connection to the other thread: Persistent issue with webGL on iPhones : Iff the issue from this thread can be resolved, then maybe it’s not necessary to look for alternatives here.

Thanks @Marco13 for linking. I that thread I described how to get the right context in older iphones.

I do get the 3D tiles, but even on new iPhone the site reload silently (I assume it crashes) on only 20K poligons. It works file on old Android phones. So I suspect an issue with iOS rendering.
