When visually viewing a 4D object, there is added depth in the shadows and how we view the light on the object. When light hits a 4D object, the shadow cast is the one that makes the 3D object appear to have more sides. Another example is in the case of 4D cubes. If you only see that outline, when the light source hits the cube from above, a shadow is then cast from one 3D cube inside another 3D cube all over the 4D outer cube. This perception of added depth comes from an additional dimension.
4D Animated Film
It’s not much different from the 3D format, it’s just that the effects of this 4D film are not only the images that come out, but there are vibrations or real effects that are produced. For example, animated films with the theme of natural life, when the scene is in water, then there is water splashed on our faces, or water vapor drips. Then when there is an earthquake, the chair we are sitting on will vibrate too, it is unique and exciting but the audience will definitely not focus on the film but only on the effect. Films in this format do not only refer to cinema screens, but also several media applications, such as a chair mover that produces vibrations, water vapor, and several other effects, including an air conditioner that can suddenly turn very cold during a snow scene, and a heater that can turn cold. heats up during the desert scene.

In mathematics, four-dimensional space (“4D”) is a geometric space with four dimensions. It typically is more specifically four-dimensional Euclidean space, generalizing the rules of three-dimensional Euclidean space. It has been studied by mathematicians and philosophers for over two centuries, both for its own interest and for the insights it offered into mathematics and related fields.
Algebraically, it is generated by applying the rules of vectors and coordinate geometry to a space with four dimensions. In particular a vector with four elements (a 4-tuple) can be used to represent a position in four-dimensional space. The space is a Euclidean space, so has a metric and norm, and so all directions are treated as the same: the additional dimension is indistinguishable from the other three.
In modern physics, space and time are unified in a four-dimensional Minkowski continuum called spacetime, whose metric treats the time dimension differently from the three spatial dimensions (see below for the definition of the Minkowski metric/pairing). Spacetime is not a Euclidean space.
