3D design is the process of creating three-dimensional objects using specialized software. This technology allows designers to visualize and manipulate shapes in a virtual space, making it easier to develop products, characters, or environments. Common applications include video games, movies, and product prototypes. In 3D design, artists can create models that can be viewed from any angle, providing a realistic representation of the final product. Tools like Blender, AutoCAD, and SketchUp are popular among designers for their ability to render detailed and accurate 3D visuals. This design method enhances creativity and efficiency in various industries.
