# [name]

Creates an texture 2D array based on data in compressed form, for example from a [link:https://en.wikipedia.org/wiki/DirectDraw_Surface DDS] file.
For use with the [page:CompressedTextureLoader CompressedTextureLoader].

## Constructor

### [name]( [param:Array mipmaps], [param:Number width], [param:Number height], [param:Constant format], [param:Constant type] )

[page:Array mipmaps] -- The mipmaps array should contain objects with data, width and height. The mipmaps should be of the correct format and type.
[page:Number width] -- The width of the biggest mipmap.
[page:Number height] -- The height of the biggest mipmap.
[page:Number depth] -- The number of layers of the 2D array texture.
[page:Constant format] -- The format used in the mipmaps. See [page:Textures ST3C Compressed Texture Formats], [page:Textures PVRTC Compressed Texture Formats] and [page:Textures ETC Compressed Texture Format] for other choices.
[page:Constant type] -- Default is [page:Textures THREE.UnsignedByteType]. See [page:Textures type constants] for other choices.

## Properties

See the base [page:CompressedTexture CompressedTexture] class for common properties.

### [property:number wrapR]

This defines how the texture is wrapped in the depth direction.
The default is [page:Textures THREE.ClampToEdgeWrapping], where the edge is clamped to the outer edge texels. The other two choices are [page:Textures THREE.RepeatWrapping] and [page:Textures THREE.MirroredRepeatWrapping]. See the [page:Textures texture constants] page for details.

### [property:Object image]

Overridden with a object containing width, height, and depth.

### [property:Set layerUpdates]

A set of all layers which need to be updated in the texture. See [Page:CompressedTextureArray.addLayerUpdate addLayerUpdate].

### [property:Boolean isCompressedArrayTexture]

Read-only flag to check if a given object is of type [name].

## Methods

### [method:addLayerUpdate addLayerUpdate]( layerIndex )

Describes that a specific layer of the texture needs to be updated. Normally when [page:Texture.needsUpdate needsUpdate] is set to true, the entire compressed texture array is sent to the GPU. Marking specific layers will only transmit subsets of all mipmaps associated with a specific depth in the array which is often much more performant.

### [method:clearLayerUpdates clearLayerUpdates]()

Resets the layer updates registry. See [Page:CompressedTextureArray.addLayerUpdate addLayerUpdate].

See the base [page:CompressedTexture CompressedTexture] class for common methods.
