Revit.DB.DirectContext Camera Class?

Hey everybody,
do you know if it is possible to “cast” a Revit.DB,View3D to a Revit.DB.DirectContext.Camera class? What even is this DirectContext namespace?

I was trying to obtain data on crop size and field of view of perspective views (View3D class), which have useful properties such as:

View3D.GetOrientation().EyePosition
View3D.GetOrientation().ForwardDirection
View3D.CropBox.Min
View3D.CropBox.Max
View3D.CropBox.Transform,OfPoint(Min)
View3D.CropBox.Transform,OfPoint(Max)

With some tinkering with dynamo geometry I am kind of able to obtain some approximations of these values:

But googling I found the Camera class which appears to have some of these properties readily available, I just do not know how to access them?
Or does this class have little to do with the 3d View and more with rendering options or what not?

Thanks
