3D Visualization is a technique that creates three-dimensional images or animations using computer software. This technology allows users to see objects from different angles and perspectives, making it easier to understand complex structures. It is widely used in fields like architecture, engineering, and medicine to present designs and concepts clearly. In architecture, for example, 3D visualization helps architects and clients visualize buildings before they are constructed. In medicine, it can be used to create detailed models of organs for better surgical planning. Overall, 3D visualization enhances communication and understanding across various industries.
