3D Model Support

[alihandemirdas]

I'm working on a 2D/3D map with Maplibre in a bare React Native project. I can display 3D buildings with elevations thanks to Maplibre's fill-extrusion feature. However, Maplibre's fill-extrusion feature can only draw straight lines; I can't create that slope for structures like sloped roofs or the sloped exteriors of stadiums.

To solve this, I'm converting my actual building model, created in Blender, to geojson structures with a script, but when I try to add it as geojson, I still can't draw the sloped areas. My goal is to display custom-modeled locations as polygons in the same scene as my Maplibre map.

Is there a way to do this? I haven't found a compatible package in bare React Native. I can't use the three package because packages like react-fiber/drei require expo, and I can't switch to expo because the project has progressed. I need to continue with bare React Native, if there's a way. I want to integrate buildings at the LOD2 LOD3 level. For example, Yandex.Maps was able to integrate this feature I wanted, but I could not find any documentation. Thanks in advance.

AFAIK MapLibre Native still has no support for 3D Models maplibre/maplibre-native#2806. So only if MapLibre Native supports 3D for Android and iOS the React Native wrapper can add it.

Thanks for your response, and I appreciate it. So, are there any other options we can use it with Maplibre? For example, libraries like deck.gl work well for the web with Maplibre, but they don't have mobile support. Thanks again.

Not that I know of. You can check out the various issues within the MapLibre Native repository or reach out to the #maplibre-native Slack channel at https://slack.openstreetmap.us/.
