Isn't one of the inherent advantages of the torus that it evens out the light fall-off for the outside positions on the screen? If you do optimize for all seats, than this is taken care of implicitly, no? Perhaps I am not getting exactly what you are trying to say (wouldn't be the first time ;-).
Not quite so simple as that. I believe it is mathematically impossible to have perfect uniformity for *every* seat in the house, one can optimize one seat completely, but not all of them. When you account for the gain curve you will find that you will get less uniformity in the corners because one edge of the screen is at an smaller angle to the viewer than the other edge (i.e. different parts of the gain curve). It them becomes an exercise in minimizing non-uniformity at the extremes of the seating area while still maintaining it in the primary seating areas. Probably possible with iterative calculations, but perhaps faster if with user intervention and a GUI to position the "light cone" for different parts of the screen.
Of course, the question is still: how much non-uniformity is too much? (10%, 20%, more, less?)
