I validate your points theoretically. However Based on my TORUS experiences, I assure you that a 2.8 custom designed pearlescent STEWART surface exhibited a gain of 3.2 to 3.5. Could it be Collimation of light , concentrated in that center? Mike may be a millionaire after all . What can be said is that in sizes from 7 wide to 16 wide, no gain change/ratio
has been observed. And I seldom have installed flat screens.
A properly designed Curved screen with a pearlescent coating( I have done 20 in 54" x 96" )on Barco 700's enhanced the color dynamics and apparent resolution where in many ways it beat a 9 inch Barco 1200 hd costing 4 times more.
The reason that curved screen was not promoted was Joe Kane and Joel Silver who know a lot of theory that in reality ignores that the eye/brain
can be the most perspicas instrument.
So yes the Silver curved screens are horrendous. But there was a company Beiner that went out of Business, that did not exhibit rgb color shift reflections.
Let's call an ace , an ace. Did you see Lethal Weapon 4. Well?
To paraphrase: Joe & Joel "F*CK*D" most of "you,they really realy F*CK*D you". In fact, most of you, projecting pcrt's unto flat fixed screens without masking or perforations,following the ISF guidelines,and those not projecting on a curved screen, where a curved screen could have been used -that excludes those that needed a rolloup situation.) make all the prostitutes in the Amsterdam red light district, on any given night, seem like a theater full of girls scouts, no more like a nun convention at the vatican.
Speaking of the POPE. Since FOR A LIMITED TIME ONLY (Y2K), he will forgive all sinners that repent. Maybe if you sell your flat screen and buy a PROPER curved one this year; then and only then, maybe,after coming to terms with yourself, your self esteem, by having undertaken the correct path of: refraining cult-following the industry's "FORNICATING VIDEO-EVANGELISTS",will grow to unimaginable levels, rewarded by the lord with EYE CANDY.
My custom comissioned 2.8 that behaved like a 3.2 torus screen exhibited, on 11' wide on a Barco HD 1200, which I installed in 1993, looks like those double stacked Vidikrons except with a picture area much much larger.
Back to the original topic:
Seems to me that Don Stewart in consultation with Gerald Nash are the only ones that can answer those two questions.
Will Kam fung please post links on his original post on the TORUS. Where we first "met", in that same thread he gave us the patent . I need both links , asap. Please ,please
