# isCube

A Boolean value that indicates whether the texture is a cube textures.

## Declaration

```swift
var isCube: Bool { get set }
```

## Discussion

Discussion Cube textures are used in skybox rendering, light probes, and environment maps. If this property’s value is true, the texture object represents a cube texture. In this case, the texture’s image data (accessible with the methods in Accessing Texture Data) contains six square images arranged vertically. The images represent the +X, -X, +Y, -Y, +Z, and -Z faces of the cube (in that order), and the dimensions property reflects this arrangement (height is six times width).
