# ClippingComponent A component that clips entities and their children to a customizable bounding box volume with feathered edges. ``` struct ClippingComponent ``` ## Overview The `ClippingComponent` provides a powerful and performant way to clip content in RealityKit. It’s particularly useful for: - Creating soft-edge effects with feathered boundaries instead of hard cuts - Creating polished spatial experiences with hierarchical clipping control Add a `ClippingComponent` to an entity by passing it to an entity’s `Entity/ComponentSet/set()` method. ```swift let windowEntity = Entity() let bounds = BoundingBox(min: SIMD3(-10, -10, -10), max: SIMD3(10, 10, 10)) var clipping = ClippingComponent(bounds: bounds) clipping.featheredEdge.falloff = .linear clipping.featheredEdge.positiveEdgeInset = [2, 2, 0.0] // 2-unit feather zone on +X & +Y edges clipping.featheredEdge.negativeEdgeInset = [0.0, 0.0, 0.0] // no feathering on negative edges clipping.shouldClipSelf = true clipping.shouldClipChildren = true windowEntity.components.set(clipping) ``` ## Topics ### Creating a clipping component [`init(bounds:)`](/documentation/RealityKit/ClippingComponent/init(bounds:)) ### Configuring clipping behavior [`shouldClipChildren`](/documentation/RealityKit/ClippingComponent/shouldClipChildren) Controls whether child entities are clipped by this component’s bounds. [`shouldClipSelf`](/documentation/RealityKit/ClippingComponent/shouldClipSelf) Controls whether the entity itself is clipped by this component’s bounds. ### Feathering clipped edges [`featheredEdge`](/documentation/RealityKit/ClippingComponent/featheredEdge-swift.property) The feathering configuration for the clipping boundaries. [`ClippingComponent.FeatheredEdge`](/documentation/RealityKit/ClippingComponent/FeatheredEdge-swift.struct) Configuration for feathering the clipping boundaries. --- Copyright © 2026 Apple Inc.
