Hi All,

What is the major difference between 4D VS 3D?

4D film or 4-D film is a marketing term for an entertainment presentation system combining a 3D film with physical effects that occur in the theatre in synchronization with the film. (Note that 4D films are not actually four-dimensional in the geometric sense of the word.) Because physical effects can be expensive to install, 4D films are most often presented in custom-built theatres at special venues such as theme parks and amusement parks. However, some movie theatres have the ability to present 4D versions of wide-release 3D films. The films Journey to the Center of the Earth (2008), and Avatar (2009) are among the films that have received a 4D treatment in certain theatres.[1]

Effects simulated in a 4D film may include rain, wind, strobe lights, and vibration. Seats in 4D venues may vibrate or move a few inches during the presentation. Other common chair effects include air jets, water sprays, and leg and back ticklers. Hall effects may include smoke, rain, lightning, air bubbles, and special smells (for example, fireworks smells at the London Eye's Experience, and gassy smells when a stinkbug sprays it in It's Tough to Be a Bug).

4D films have occasionally been marketed as 5D, 6D, or 7D films in order to emphasize the variety or uniqueness of their theatre effects. However, there is no consistent standard among films for the application of these marketing labels

 I remember being at the tree of life years ago with my grandkids and they had a bee 3D presentation and when the bee comes at you the seat would give a buzz with asmall prog in your back to scare you. The grandkids were screaming their heads off.

I think the answer is not about stereoscopic movies. Cinema 4D is simply called 4D instead of 3D because it adds a 4th "dimension": animation, on top of rendering 3D still images.

A marketing term I agree, since any serious 3D program can do animation too.

Yep, the "4D" in the name refers to animation (historical PS: the first version of CINEMA 4D was released in 1993; it was called FastRay before that).

Thanks for your responses.

Is IRON MAN 3 is 4D film?

CINEMA 4D was used in Iron Man 3, yes.

Cool..
