# isInEquirectangularProjection

A Boolean value that indicates whether the generated mask texture is in equirectangular projection space. If true, the app renderer needs to transform vertices of the mesh to equirectangular projection space to generate UVs to access the mask texture.

## Declaration

```swift
var isInEquirectangularProjection: Bool { get }
```
