TypeScript

get jointTransforms(): Array<SDKHandle>

Swift declaration

let jointTransforms: [float4x4]

Current transformation matrices for each joint in the skeleton hierarchy, in joint order.

get · iOS 27.0+

TypeScript

get influenceWeights(): Array<number>

Swift declaration

let influenceWeights: [Float]

Influence weights (0.0–1.0) corresponding 1:1 with `influenceJointIndices`. Weights for each vertex sum to 1.0.

TypeScript

get inverseBindPoses(): Array<SDKHandle>

Swift declaration

let inverseBindPoses: [float4x4]

Inverse bind-pose transformation matrix for each joint.

TypeScript

get geometryBindTransform(): SDKHandle

Swift declaration

let geometryBindTransform: float4x4

Transform from world space into bind space of the skinned mesh.

get · iOS 27.0+

TypeScript

get influenceJointIndices(): Array<number>

Swift declaration

let influenceJointIndices: [UInt32]

Joint indices for each vertex-influence slot, with `influencePerVertexCount` consecutive entries per vertex.

get · iOS 27.0+

TypeScript

get influencePerVertexCount(): number

Swift declaration

let influencePerVertexCount: UInt8

Number of joint influences per vertex. Uniform across all vertices.
