Field Of View (FOV) in tangent of the angle units. As an example, for a standard 90 degree vertical FOV, we would have:
```
 { UpTan = tan(90 degrees / 2), DownTan = tan(90 degrees / 2) }
```
Member documentation
- UpTan – tangent of the angle between the viewing vector and top edge of the FOV
- DownTan – tangent of the angle between the viewing vector and bottom edge of the FOV
