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.

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.
