3D modeling is the process of creating a three-dimensional representation of an object or scene using specialized software. This digital model can be manipulated and viewed from different angles, allowing designers to visualize their ideas in a realistic way. Common applications include video games, movies, and product design. Artists and designers use various techniques to create 3D models, such as polygonal modeling, sculpting, and texturing. Once completed, these models can be used for animations, simulations, or even 3D printing, making them versatile tools in fields like architecture, engineering, and entertainment.
