# LowLevelRenderer.Camera The view and projection parameters for a single camera. ``` struct Camera ``` ## Topics ### Creating a camera [`init(position: SIMD3, rotation: simd_quatf, projection: LowLevelRenderer.Camera.Projection, viewportArrayIndex: Int, renderTargetArrayIndex: Int)`](/documentation/RealityKit/LowLevelRenderer/Camera/init(position:rotation:projection:viewportArrayIndex:renderTargetArrayIndex:)) Creates a camera with the given position, rotation, projection, and viewport/render-target indices. ### Configuring the projection [`var projection: LowLevelRenderer.Camera.Projection`](/documentation/RealityKit/LowLevelRenderer/Camera/projection-swift.property) The projection transform for this camera. [`struct Projection`](/documentation/RealityKit/LowLevelRenderer/Camera/Projection-swift.struct) A projection transform that maps from view space to clip space. ### Specifying render targets [`var renderTargetArrayIndex: Int`](/documentation/RealityKit/LowLevelRenderer/Camera/renderTargetArrayIndex) The index into the render target texture array slice for this camera. [`var viewportArrayIndex: Int`](/documentation/RealityKit/LowLevelRenderer/Camera/viewportArrayIndex) The index into the output viewports and scissor rects arrays for this camera. ### Computing culling planes [`func computeCullingPlanes() -> [LowLevelRenderer.CullConfiguration.Plane]`](/documentation/RealityKit/LowLevelRenderer/Camera/computeCullingPlanes()) Computes and returns the culling planes for this camera’s view volume. [`func computeCullingPlanes(inout OutputSpan)`](/documentation/RealityKit/LowLevelRenderer/Camera/computeCullingPlanes(_:)) Computes the culling planes for this camera’s view volume, writing them to an output span. ### Instance Properties [`var position: SIMD3`](/documentation/RealityKit/LowLevelRenderer/Camera/position) The position of the camera in world space. [`var rotation: simd_quatf`](/documentation/RealityKit/LowLevelRenderer/Camera/rotation) The orientation of the camera, expressed as a unit quaternion. --- Copyright © 2026 Apple Inc.
