3D design refers to the creation and manipulation of three-dimensional digital models and environments using specialized software and techniques. It involves the use of computer-generated imagery (CGI) to represent objects or spaces in a virtual three-dimensional space.

In 3D design, designers create and manipulate digital models that can be viewed and interacted with from any angle. They utilize various tools and software to shape and texture objects, define lighting conditions, and apply realistic materials and textures.

3D design finds applications in various industries, including architecture, product design, gaming, film, and visual effects. It allows designers to visualize and communicate ideas more effectively, as they can create realistic representations of objects or spaces before they are physically produced.

Designers use 3D design to explore different design options, assess scale and proportions, and simulate real-world interactions. They can experiment with different materials, textures, and lighting conditions to achieve the desired look and feel.

With the advancement of technology, 3D design has become increasingly accessible and versatile. It enables designers to create realistic animations, virtual reality experiences, and immersive simulations.

In summary, 3D design involves the creation and manipulation of three-dimensional digital models and environments. It allows designers to visualize and communicate ideas more effectively, explore design options, and simulate real-world interactions. 3D design finds applications in architecture, product design, gaming, film, and various other industries, enhancing the design process and enabling the creation of immersive experiences.
