## ### 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` | `true` | 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.
Inferred from parent source only if the layer is a direct child to it. | | 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 | ### styles * visibility

___ #### visibility Name: `visibility` #### Description Whether this layer is displayed. #### Type `enum` #### Default Value `visible` #### Supported Values **visible** - The layer is shown.
**none** - The layer is not shown.
___ #### fillExtrusionOpacity 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` #### Default Value `1` #### Minimum `0` #### Maximum `1` #### Expression Parameters: `zoom` ___ #### Name `fillExtrusionOpacityTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionOpacity propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionColor 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` #### Expression Parameters: `zoom, feature, feature-state` ___ #### Name `fillExtrusionColorTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionColor propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionTranslate Name: `fillExtrusionTranslate` #### Description The geometry's offset. Values are [x, y] where negatives indicate left and up (on the flat plane), respectively. #### Type `array` #### Default Value `[0,0]` #### Units `pixels` #### Expression Parameters: `zoom` ___ #### Name `fillExtrusionTranslateTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionTranslate propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionTranslateAnchor 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.
**viewport** - The fill extrusion is translated relative to the viewport.
#### Requires `fillExtrusionTranslate` #### Expression Parameters: `zoom` ___ #### fillExtrusionPattern 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). Note that zoomDependent expressions will be evaluated only at integer zoom levels. #### Type `resolvedImage` #### Expression Parameters: `zoom, feature` ___ #### Name `fillExtrusionPatternTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionPattern propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionHeight Name: `fillExtrusionHeight` #### Description The height with which to extrude this layer. #### Type `number` #### Default Value `0` #### Units `meters` #### Minimum `0` #### Expression Parameters: `zoom, feature, feature-state` ___ #### Name `fillExtrusionHeightTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionHeight propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionBase Name: `fillExtrusionBase` #### Description The height with which to extrude the base of this layer. Must be less than or equal to `fillExtrusionHeight`. #### Type `number` #### Default Value `0` #### Units `meters` #### Minimum `0` #### Requires `fillExtrusionHeight` #### Expression Parameters: `zoom, feature, feature-state` ___ #### Name `fillExtrusionBaseTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionBase propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionVerticalGradient Name: `fillExtrusionVerticalGradient` #### Description Whether to apply a vertical gradient to the sides of a fillExtrusion layer. If true, sides will be shaded slightly darker farther down. #### Type `boolean` #### Default Value `true` #### Expression Parameters: `zoom` ___ #### fillExtrusionAmbientOcclusionIntensity Name: `fillExtrusionAmbientOcclusionIntensity` #### Description Controls the intensity of ambient occlusion (AO) shading. Current AO implementation is a lowCost bestEffort approach that shades area near ground and concave angles between walls. Default value 0.0 disables ambient occlusion and values around 0.3 provide the most plausible results for buildings. #### Type `number` #### Default Value `0` #### Minimum `0` #### Maximum `1` #### Expression Parameters: `zoom` ___ #### Name `fillExtrusionAmbientOcclusionIntensityTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionAmbientOcclusionIntensity propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### fillExtrusionAmbientOcclusionRadius Name: `fillExtrusionAmbientOcclusionRadius` #### Description The radius of ambient occlusion (AO) shading, in meters. Current AO implementation is a lowCost bestEffort approach that shades area near ground and concave angles between walls where the radius defines only vertical impact. Default value 3.0 corresponds to hight of one floor and brings the most plausible results for buildings. #### Type `number` #### Default Value `3` #### Minimum `0` #### Expression Parameters: `zoom` ___ #### Name `fillExtrusionAmbientOcclusionRadiusTransition` #### Description The transition affecting any changes to this layer’s fillExtrusionAmbientOcclusionRadius propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}`
