# MTLMapIndirectArguments

The data layout for mapping sparse texture regions when using indirect commands.

## Declaration

```swift
struct MTLMapIndirectArguments
```

## Topics

### Creating indirect mapping arguments

- [init()](metal/mtlmapindirectarguments/init().md)
- [init(regionOriginX:regionOriginY:regionOriginZ:regionSizeWidth:regionSizeHeight:regionSizeDepth:mipMapLevel:sliceId:)](metal/mtlmapindirectarguments/init(regionoriginx:regionoriginy:regionoriginz:regionsizewidth:regionsizeheight:regionsizedepth:mipmaplevel:sliceid:).md)

### Specifying region origin

- [regionOriginX](metal/mtlmapindirectarguments/regionoriginx.md)
- [regionOriginY](metal/mtlmapindirectarguments/regionoriginy.md)
- [regionOriginZ](metal/mtlmapindirectarguments/regionoriginz.md)

### Specifying region dimensions

- [regionSizeWidth](metal/mtlmapindirectarguments/regionsizewidth.md)
- [regionSizeHeight](metal/mtlmapindirectarguments/regionsizeheight.md)
- [regionSizeDepth](metal/mtlmapindirectarguments/regionsizedepth.md)

### Specifying texture location

- [mipMapLevel](metal/mtlmapindirectarguments/mipmaplevel.md)
- [sliceId](metal/mtlmapindirectarguments/sliceid.md)

## Relationships
