Define "3D modeling" in the context of multimedia.

3D modeling refers to the process of creating three-dimensional representations of objects or scenes using specialized software. This process involves building a digital structure that can be viewed, manipulated, and rendered from different angles, providing a realistic representation of volume, depth, and surface texture. In multimedia, 3D modeling is essential for applications such as video games, animations, simulations, and virtual reality environments, where a realistic three-dimensional experience is crucial.

This process often includes defining the object's geometry, adding textures, colors, and lighting effects to enhance realism. The end result can be used for various purposes, including visual effects in films, architectural visualization, product prototypes, and more, making it a versatile and foundational skill in many areas of multimedia.
