While active 3D technology is the most common type, movie theater glasses will work in your home if you have a passive system. Also read: How to watch 3D movies at home. As part of that level of immersion, movie theaters use the most cutting-edge technology. I doubt it comes as a surprise to anyone that much of the technology we enjoy at home was made for theaters.
This is definitely true of 3D technology, and particularly 3D projectors. Movie theaters use passive technology, which is much more expensive. However, this makes the glasses cheaper, which is a more suitable business model for movie theaters. Typically they use RealD 3D glasses source , which are marketed as cinema level technology. These are polarized 3D glasses. The real deciding factor is the type of TV or monitor you own. If you want to use movie theater 3D glasses at home, then make sure your 3D TV or projector supports passive 3D technology.
When it comes to whether you should use movie theater 3D glasses at home, well I guess this would depend on your budget. As I mentioned earlier, there are 2 kinds of 3D technology: active and passive. This terminology refers to the glasses, but obviously also impacts the way the image is produced. But what do these terms mean, and which is better? The RealD 3D glasses used in movie theaters are passive polarized glasses, which is typically used in movie theaters.
These basically use the same kind of technology as the red and blue 3D glasses you probably had as a child. Essentially, they filter the image so that each eye only sees half of it. Passive 3D technology is much more readily available and is generally cheaper. The price for the 3D technology comes from the projectors or TVs.
Most of the work is done by the projector, which means this kind of system is ideal for movie theaters, but is less common in home settings. Active 3D technology, on the other hand, uses more complicated glasses. As with other home theater technologies, active refers to the fact that they have a power source.
In this case, the power source is a battery contained in the glasses. Rather than polarizing the image so that each eye only sees half, active glasses have a shutter built into them. They alternate between each eye at a very rapid speed, which again tricks your brain into thinking that the image is 3D. Also, this allows you to see a full image, rather than only half.
Ultimately, this means that the projectors and TVs that produce active 3D images are actually much cheaper, and so are more accessible to a home market. When it comes to the main differences between active and passive 3D glasses, the most obvious one is price. Imax Digital 3D: This is a similar format that also uses polarizing glasses. Imax Digital 3D is an evolutionary improvement of analog Imax 3D theaters that have been around since Its long history is evident even in the much newer Imax Digital 3D theaters since they still utilize the linear polarizing technology of its analog predecessors.
Unlike RealD, Imax 3D movies are less tolerant of head movements. Viewers have to avoid tilting their heads, though some turning—probably unavoidable due to the massive Imax screen format—is possible. Note: We will not be discussing analog Imax 3D theaters for this article since it is meant to contrast the two dominant digital 3D formats currently available in cinemas. Theater audiences are paying more for Imax 3D movies for a few possible reasons. The first being the much larger screen such cinemas are known for that could contribute to a more immersive 3D experience.
Other reasons include better sound and a potentially brighter image. Imax Digital 3D theaters, on the other hand, use Christie 2K dual-projector systems which give the same resolution as full-HD. News Stories. An overview: RealD 3D vs. Imax Digital 3D.
