## Topics

### Creating a strategy

[`static func screenArea([Float]) -> LevelOfDetailComponent.SelectionStrategy`](/documentation/RealityKit/LevelOfDetailComponent/SelectionStrategy/screenArea(_:))

Switch levels based on projected screen area (0.0 = invisible, 1.0 = fills screen).

[`static func cameraDistance([Float]) -> LevelOfDetailComponent.SelectionStrategy`](/documentation/RealityKit/LevelOfDetailComponent/SelectionStrategy/cameraDistance(_:))

Switch levels based on distance from the camera.

### Selecting by resolution metric

[`static func resolutionMetric(switchingResolutions: [LevelOfDetailComponent.SelectionStrategy.ResolutionMetric.DirectionalSwitchingResolutions], boundingBox: BoundingBox) -> LevelOfDetailComponent.SelectionStrategy`](/documentation/RealityKit/LevelOfDetailComponent/SelectionStrategy/resolutionMetric(switchingResolutions:boundingBox:))

Creates a resolution metric for a level of detail component to switch with.

[`struct ResolutionMetric`](/documentation/RealityKit/LevelOfDetailComponent/SelectionStrategy/ResolutionMetric)
