## Declaration

```swift
init(leftTangent: Float, rightTangent: Float, topTangent: Float, bottomTangent: Float, nearZ: Float, farZ: Float, reverseZ: Bool)
```

## Parameters

- `leftTangent`: The left tangent.
- `rightTangent`: The right tangent.
- `topTangent`: The top tangent.
- `bottomTangent`: Bottom left tangent.
- `nearZ`: The near @p z .
- `farZ`: The far @p z .
- `reverseZ`: A Boolean value that specifies whether the matrix should use reverse z.

## Return Value

Return Value A projective transform from tangents for each side of its frustum.
