3D is going through a cycle of popularity, and it is not
last, but this time there seems to be a lot of technicalinnovation which
has resulted in acceptable presentation to groups. Buteach method has
problems. So far the best method for home presentationseems to be using
circular polarization to separate right and left images,but it has problems
as all the methods do. So can anyone come up with someideas for fixing
some of the problems. Here is a list of current methods:
My last trip to Costco included a demo 3-D. I viewed thru
the glasses grazing reflection from a nearby slickly covered
box. Rotating the glasses caused partial extinction
(oxymoron, I know) of the reflection. So I concluded linear
polarizers. *** this is how my projector works. I't been >

UCSC, so I may be all wet.

confused -- I could google instead of posting.
The FPR method is currently cheapest, and is fairly satisfactory
except when you want to mix 2D and 3D. It makes 2D small
fonts hard to
read.
There goes closed captioning.
