# USDPlayer.DeformationData.SkinningData

Joint deformation data for a skinned mesh.

```
struct SkinningData
```

## Topics

### Structures

[`struct Update`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/Update)

Delta update carrying only the skinning fields that changed since the last frame.

### Instance Properties

[`let geometryBindTransform: float4x4`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/geometryBindTransform)

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

[`let influenceJointIndices: [UInt32]`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/influenceJointIndices)

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

[`let influencePerVertexCount: UInt8`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/influencePerVertexCount)

Number of joint influences per vertex.

[`let influenceWeights: [Float]`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/influenceWeights)

Influence weights (0.0–1.0) corresponding 1:1 with `influenceJointIndices`.

[`let inverseBindPoses: [float4x4]`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/inverseBindPoses)

Inverse bind-pose transformation matrix for each joint.

[`let jointTransforms: [float4x4]`](/documentation/USDKit/USDPlayer/DeformationData/SkinningData/jointTransforms)

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