Anywhere. It's one of the kind from me. "4D" has several meanings, but most commonly refers to four-dimensional space, a theoretical mathematical concept extending 3D space by an additional spatial direction, often visualized as time. In common language, 4D can also mean a four-door vehicle or a special 4D effect in movies that adds a physical element like wind or motion to 3D images.
In mathematics and physics:
Four-dimensional space: This is the most technical use of 4D, describing a space with four coordinates (x, y, z, w) where the fourth coordinate is a new direction not found in our familiar 3D world.
Time as the Fourth Dimension: Time itself is often considered the fourth dimension, where events are described by their location in space (x, y, z) and their occurrence at a specific time.
