3D modeling refers to the process of creating a digital representation of a three-dimensional object or scene. 3D models are created using computer-aided design (CAD) software, which allows users to define the shape, size, texture, and other properties of an object. The resulting 3D model can be used for a variety of purposes, such as product design, animation, visual effects, and virtual reality experiences. The process of 3D modeling typically involves several steps, including defining the basic shape and structure of the object, adding details and textures, and creating animations or simulations. 3D modeling skills are in high demand in industries such as architecture, product design, film and gaming, and engineering. The goal of 3D modeling is to create a realistic and accurate representation of an object or scene that can be used for various purposes.
