# rWrapMode

The coordinate wrapping mode for texture r-coordinates.

## Declaration

```swift
var rWrapMode: MDLMaterialTextureWrapMode { get set }
```

## Discussion

Discussion Texture coordinates canonically range from 0.0 to 1.0; wrap mode determines the behavior for samples from outside that range. For details, see MDLMaterialTextureWrapMode. The r-coordinate is the third value in a set of texture coordinates, used only with three-dimensional textures.
