## <MapboxGL.FillExtrusionLayer />
### FillExtrusionLayer is a style layer that renders one or more 3D extruded polygons on the map.

### props
| Prop | Type | Default | Required | Description |
| ---- | :--: | :-----: | :------: | :----------: |
| id | `string` | `none` | `false` | A string that uniquely identifies the source in the style to which it is added. |
| sourceID | `string` | `MapboxGL.StyleSource.DefaultSourceID` | `false` | The source from which to obtain the data to style. If the source has not yet been added to the current style, the behavior is undefined. |
| sourceLayerID | `string` | `none` | `false` | Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style. |
| aboveLayerID | `string` | `none` | `false` | Inserts a layer above aboveLayerID. |
| belowLayerID | `string` | `none` | `false` | Inserts a layer below belowLayerID |
| layerIndex | `number` | `none` | `false` | Inserts a layer at a specified index |
| filter | `array` | `none` | `false` | Filter only the features in the source layer that satisfy a condition that you define |
| minZoomLevel | `number` | `none` | `false` | The minimum zoom level at which the layer gets parsed and appears. |
| maxZoomLevel | `number` | `none` | `false` | The maximum zoom level at which the layer gets parsed and appears. |
| style | `union` | `none` | `false` | Customizable style attributes |

___

#### Name
`visibility`

#### Description
Whether this layer is displayed.

#### Type

#### Supported Values
**visible** - The layer is shown.<br />
**none** - The layer is not shown.<br />



___

#### Name
`fillExtrusionOpacity`

#### Description
The opacity of the entire fill extrusion layer. This is rendered on a perLayer, not perFeature, basis, and dataDriven styling is not available.

#### Type
`number`

`1`

#### Supported Style Functions
`camera`

___

#### Name
`fillExtrusionColor`

#### Description
The base color of the extruded fill. The extrusion's surfaces will be shaded differently based on this color in combination with the root `light` settings. If this color is specified as `rgba` with an alpha component, the alpha component will be ignored; use `fillExtrusionOpacity` to set layer opacity.

#### Type
`color`
#### Default Value
`#000000`


#### Disabled By
`fillExtrusionPattern`

#### Supported Style Functions
`camera, source, composite`

___

#### Name
`fillExtrusionTranslate`

#### Description
The geometry's offset. Values are [x, y] where negatives indicate left and up (on the flat plane), respectively.

#### Type
`array<number>`
#### Default Value
`[0,0]`

#### Units
`pixels`


#### Supported Style Functions
`camera`

___

#### Name
`fillExtrusionTranslateAnchor`

#### Description
Controls the frame of reference for `fillExtrusionTranslate`.

#### Type
`enum`
#### Default Value
`map`

#### Supported Values
**map** - The fill extrusion is translated relative to the map.<br />
**viewport** - The fill extrusion is translated relative to the viewport.<br />


#### Requires
`fillExtrusionTranslate`

#### Supported Style Functions
`camera`

___

#### Name
`fillExtrusionPattern`

#### Description
Name of image in sprite to use for drawing images on extruded fills. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512).

#### Type
`string`


#### Supported Style Functions
`camera`

___

#### Name
`fillExtrusionHeight`

#### Description
The height with which to extrude this layer.

#### Type
`number`
#### Default Value
`0`

#### Units
`meters`

#### Minimum
`0`


#### Supported Style Functions
