What is 4d: Definition and 127 Discussions

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. Effects simulated in a 4D film may include rain, mist, bubbles, fog or smoke, wind, temperature changes, strobe lights, scent, vibration and motion. Seats in 4D venues may vibrate or move a few centimeters during the presentations. Other common chair effects include air jets, water sprays, and leg and back ticklers. Auditorium effects may include smoke, rain, lightning, bubbles, and smell.
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, amusement parks and zoos. 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. There are also mobile 4D theaters, which are mounted inside vehicles such as enclosed trailers, buses and trucks.
4D films are distinct from four-dimensional space. Notable historical formats for providing different aspects of a "fourth dimension" to films include Sensurround, and Smell-O-Vision. As of June 2015, about 530 screens worldwide have installed some 4D technology.

    How would your body change if you were in a 4D space?

    I don't believe this question will interest anyone else, but remains worthy of notice because the solution is a formula that depends on the 36th root of a number. You unexpectedly find yourself in a space with four Euclidean dimensions. Fortunately your molecules have been rearrange into a four...

    A 4D HyperEarth: 1000x More Space for Real Estate

    Let’s dubiously assume that these 4D atoms would have the same radius as 3D atoms. Let’s further dubiously assume that a 4D HyperEarth has the same number of atoms as 3D Earth. Then the diameter of HyperEarth would be less than a kilometer. Four dimensional Earth is much more compact. Wouldn’t...

    I 4d integration/differentiation notation and the total derivative

    This is probably a stupid question but, ## \frac{d\partial_p}{d\partial_c}=\delta^p_c ## For the notation of a 4D integral it is ##d^4x=dx^{\nu}##, so if I consider a total derivative: ##\int\limits^{x_f}_{x_i} \partial_{\mu} (\phi) d^4 x = \phi \mid^{x_f}_{x_i} ## why is there no...

    Equator of a Planet with Four Spatial Dimensions is a 4D Torus

    A 4D planet has no axis of rotation. Nothing special about planets, all freely rotating 4D bodies have two perpendicular planes of rigid rotation. (Clifford proved this in the 19th century.) Now there is nothing stopping us from thinking of planes of rotation here in 3D Universe. It's the...

    Suppose I have two intersecting planes in a four dimensional space. It seems to me that there are two angles between these planes. If the two planes intersect in a line then one of those angles is zero. If the two angles are non-zero then the planes intersect in a point. If one plane is the...
