I didn’t really know where to put this so i put in in the most general topic.
I just came back from the movies and kept the 3D glasses thinking it might be possible to do something in blender.
Is it possible to use the glasses to view your animations in 3D? Any tutorials anywhere?
Btw its not the red and blue paper ones, its the black polarized ones used when watching avatar or any of the new movies
Unfortunately you can’t use the polarized glasses at home to view something in 3D (unless you have two beamers, two polarisation filters and a silver screen or some modern high-end monitor that is capable of showing 3D content).
With the red/blue-ones the situation would be different. These can also be used with a normal monitor (you just have to render two versions of a scene and then combine the two renders to one stereoscopic picture).
I don’t have those. Heck, not even cheap blue-red glasses.
in any case, generating the images is the same, you always render 2 frames. Joining them in an image editor is different: you just put side by side left image to the right and vice-versa for no-glasses, cross-eyes view and for glasses you put right image to the right and left image to the left, superimposed over right image, just a bit to the side. With glasses you gotta make color filtering in the colored glasses case and I have no clue what should be needed for polarized glasses…
You can use those same “Real D” glasses, but you’d need some hardware. First you’d need two LCD or DLP projectors. For each of them you’d need “circular polarizing” filters. It is the circular part that makes Real D work so well. You can tilt your head without screwing up the affect. You can purchase the filters ($175-290 US) here:
You can’t use your wall or a cheap screen for this though, or the polarization will be lost and the effect gone. The biggest manufacturer is DaLite and they will sell you fabric. One is called “3D Virtual Grey”. Their website is here:
Our local theater usually has pre-recorded announcements before the movie and before 3D movies state that taking the glasses home is against theater policy, in other words they require you to return the glasses.
You may have violated the policy of your theater by taking the glasses home and should return them soon.
You mean the glasses that use the new technology, you can’t return them!?
That’s nuts. our theater re-uses all of the glasses that were worn after the movie’s over and they are returned, they have the ability to wipe and clean the glasses so they are usable again.
Also, our locally based theater chain is upgrading to a better 3D technology (the X-span 3D technology), things will get even sweeter with a significant sound system upgrade and a new imax screen at the theater less than a mile from our house. (according to recent news from our main media outlets and current plans, it will be even bigger than the average imax screen at 6 stories high and 90 feet wide, one of the biggest screens in the world)
Don’t worry i didn’t steal them, you pay 3 dollars for them and then there is a sign that says to be environmentally friendly and to please recycle them, then there is a cardboard box where people put em in. So even if i had a 3D tv or projector, i wouldn’t be able to do it with the glasses the tv came with? that sucks
@JoOngle. Your idea of using glasses for filters would probably not be worth the trouble, especially since it is only saving $200 when you are using $2000 worth of projectors.
With the projectors I have on hand, the lenses on the glasses are too small if mounted externally to filter the entire image. The curvature of them also causes issues. Those filters I linked to are large, square, flat, and easily mountable at a small distance from the projector (you need a gap or the heat will do damage).
