3D Modeling

Definition

3D modeling is the process of creating a three-dimensional representation of any object or surface using specialized software. This technique allows for the visualization and manipulation of objects in a virtual space, making it an essential tool in various fields such as design, engineering, and entertainment. By converting real-world objects into digital formats, 3D modeling enhances data visualization and supports decision-making through clear, interactive representations of complex information.
