# USDPlayer.DeformationData.RenormalizationData

Triangle adjacency data for post-deformation normal renormalization.

```
struct RenormalizationData
```

## Topics

### Structures

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

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

### Instance Properties

[`let vertexAdjacencies: [UInt32]`](/documentation/USDKit/USDPlayer/DeformationData/RenormalizationData/vertexAdjacencies)

Flattened list of triangle face indices adjacent to each vertex.

[`let vertexAdjacencyEndIndices: [UInt32]`](/documentation/USDKit/USDPlayer/DeformationData/RenormalizationData/vertexAdjacencyEndIndices)

Cumulative end indices into `vertexAdjacencies`, one per vertex.

[`let vertexIndicesPerTriangle: [UInt32]`](/documentation/USDKit/USDPlayer/DeformationData/RenormalizationData/vertexIndicesPerTriangle)

Vertex indices for each triangle, stored as three consecutive indices per triangle.
