# LowLevelDeformation.VertexSemantic

Designates the intended usage of a vertex attribute.

```
enum VertexSemantic
```

## Topics

### Identifying vertex attributes

[`case position`](/documentation/RealityKit/LowLevelDeformation/VertexSemantic/position)

The semantic for vertex position data.

[`case normal`](/documentation/RealityKit/LowLevelDeformation/VertexSemantic/normal)

The semantic for surface normal data.

[`case tangent`](/documentation/RealityKit/LowLevelDeformation/VertexSemantic/tangent)

The semantic for surface tangent vector data.

[`case bitangent`](/documentation/RealityKit/LowLevelDeformation/VertexSemantic/bitangent)

The semantic for surface bitangent vector data.

[`case uv`](/documentation/RealityKit/LowLevelDeformation/VertexSemantic/uv)

Texture coordinate (for input to renormalization).
