The view parameters (2)
The view direction
(-vd) is simply the vector from the view point previously calculated back to the surface (along the normal).
The view up (-vu)
is determined by interrogating the surfaces orientation.
The width &
height (-vh, -vv) are matched to the dimensions of the surface.
