I understand you are not happy about having to put your had in your pocket to fix your projector, and I'm sorry to be so blunt, but its seems you are a little out of touch with the reality of running a "business".
A guy who mows laws for a living charges around $100 per hour and doesnt have to pay rent on premises, pay staff including sick pay, long service leave and superannuation. Pay accountants to do GST returns, company tax returns, weekly staff payroll etc. Pay for insurance on premises and public liability. Cover the cost of warranty on your own work etc, etc, etc, and MAKE A PROFIT because its a "business" not a charity. PLUS, after all that hand over about one third of what profit you do make to the government.
Still reckon you are in the "wrong line of business"? I hope you never have to call a plumber.
My understanding is that the system works by taking the original Left and Right stereoscopic views, synthesizing intermediate stereoscopic views, and then projecting this range of separate views across each seating position.
Here's my own quick diagram illustrating the general approach:-
ADULT VIEWER SEATED IN DEAD CENTRE OF CHAIR
Full right ==>
Outer right ==> ( RIGHT EYE
Inner right ==>
Central ==> < NOSE
Inner left ==>
Outer left ==> ( LEFT EYE
Full left ==>
Ive always put this conundrum down to persistence of vision with the brain melding the 2 images Mark but that is a simplistic view possibly
You will be heartened by the work being done by Douglas Trumble who has the means now ; 4k and digital cinema frame rates to revolutionise cinema viewing
So back to projection, the link doesn't really shed light on how the system might work. 3D is made up of two 2D perspective images. How does the brain separate these left and right images? With the current 3D, if you take the glasses off, you see both the left and right eye perspective at the same time, even though both images are being displayed L R L R L R. The images are being refreshed way too fast for our eyes to see a difference, so we see a blurred double image. It is the shutters of the glasses that allow us to see the two images independently.
