Avatar 2 was converted from 2D into 3D in post, like it says so in the Credits.

Transformers DOTM is also a 3D conversion.

Gravity is another conversion.

Judge Dredd movie from like 2012 is also a 3D conversion.

None of these movies were filmed in 3D, as mentioned in their Credits.

Transformers Age of Extinction and Avatar 1 are the only Native 3D movies you people have mention.

Also they release around 50 movies in 3D a year every year since 2010, at least here in America (United States) anyways. I saw Mission Impossible and James Bond in 3D. I can\'t wait to see Indiana Jones 5 in 3D. I wish I saw the 3D Trailer for Transformers ROTB in 3D that everyone else saw. Oh welp, I should see it when i go see Titanic or Ant-Man 3 or Super Mario or Guardians of the Galaxy 3 or Little Mermaid or Spider-Verse in 3D.

 

3D rigs are known as mirror rigs or beam splitter rigs, which is what Cameron used for Avatar 2.

So... are there any special effects that you feel while watching it?

 

As mention in the Credits of Avatar 2, only some scenes where filmed with 3D cameras while most scenes were converted from 2D into 3D, as in an Post Conversion.

 

oh we\'re STARVING huh..

 

The depth was the special effects. Felt like you were looking through a window when they were underwater
