# ClothPoseResource A resource that defines a set of vertex positions for a cloth body. ``` final class ClothPoseResource ``` ## Overview A pose resource provides an alternate set of positions for the vertices of a [`ClothMeshResource`](/documentation/RealityKit/ClothMeshResource); the topology is still determined by the mesh resource. One common use is to specify an already-draped starting configuration via [`initialMeshDraping`](/documentation/RealityKit/ClothBodyComponent/initialMeshDraping). ## Topics ### Creating a pose resource [`convenience init(positions: [SIMD3]) throws`](/documentation/RealityKit/ClothPoseResource/init(positions:)) Creates a cloth pose resource with the given vertex positions. ### Accessing pose positions [`func withPositions((Span>) -> Result) -> Result`](/documentation/RealityKit/ClothPoseResource/withPositions(_:)) Provides access to the positions of all the vertices within a callback. [`func position(at: UInt32) -> SIMD3`](/documentation/RealityKit/ClothPoseResource/position(at:)) Returns the position of the vertex at the given index. [`var vertexCount: Int`](/documentation/RealityKit/ClothPoseResource/vertexCount) The number of vertices in the pose resource. ## Relationships ### Conforms To [`Resource`](/documentation/RealityKit/Resource) [`Sendable`](/documentation/Swift/Sendable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
