4D Visualization is a technique that adds a time dimension to traditional 3D Visualization. While 3D visualization allows us to see objects in three dimensions—length, width, and height—4D visualization incorporates the element of time, enabling users to observe changes and movements over a period. This is particularly useful in fields like architecture, engineering, and medical imaging. In practice, 4D visualization can be used to simulate how a building will look as it is constructed or how a patient’s anatomy changes over time. By integrating time into the visual experience, it provides a more dynamic and comprehensive understanding of complex data and processes.
