# MeshDeformer

An interface for all deformation types in a deformation definition, both built-in and custom. The users overrides all functions to implement a custom MeshDeformer, and can in general ignore all but the constructors for built-in deformers.

## Declaration

```swift
protocol MeshDeformer : Decodable, Encodable, Equatable, Sendable
```

## Topics

### Identifying the deformer

- [type](realitykit/meshdeformer/type-swift.type.property.md)
- [type](realitykit/meshdeformer/type-nxsx.md)

### Configuring deformation options

- [options](realitykit/meshdeformer/options.md)

### Deforming the mesh
