How to adjust the resolution of a SceneView?

IgnisDev

Hello!

I am using the ArcGIS SDK for Swift to display a 3D scene like this:

 

struct MySceneView: View {
    @StateObject private var vm = MySceneViewModel()

    var body: some View {
        SceneView(scene: vm.scene)
    }
}

@MainActor
final class MySceneViewModel: ObservableObject {
    @Published var scene = Scene(basemapStyle: .arcGISTopographic)

    init() {
        let camera = Camera(
            latitude: 37.752,
            longitude: -122.431,
            altitude: 800,
            heading: 0,
            pitch: 0,
            roll: 0
        )

        scene.initialViewpoint = .init(
            boundingGeometry: camera.location,
            rotation: 0,
            camera: camera
        )
    }
}

 

While the scene itself renders correctly, the font sizes of the labels on the base map are too small, making them difficult to read. This issue also occurs when I add a vector layer to the scene; both the labels and icons appear undersized.

I suspect that the problem is happening because the SceneView is rendering the base map at a 1x scale. On Retina displays, where the pixel density is 2x or 3x, this results in smaller visual elements. Is there a way to adjust the scale or resolution of the SceneView so that the elements become more readable on high-density displays?

Thank you!

Thanks for reporting this issue.

The root cause is that the labels base layer in our scene is rasterized, not kept as vector as in a map (like in other competitor 3D maps). I've passed this feedback to our team and will let you know what we're gonna do to fix this.
