Notes
The Throw ratio for a particular lens
is fixed, but assumes that the image
fills the width of the DMD.
For images that do not fill the width
of the DMD, the throw ratio is
effectively increased. To correct for
this in these calculations, a throw
ratio factor is used.
Throw distance calculations are
based on the distance from the outer
end of the lens, which will vary from
lens to lens.
