Which of the following modelling methods uses Boolean operations?

Explanation:

• Boolean operation is an important way in geometry modeling.
• It is the main way to build a complex model from simple models, and it is widely used in computer-aided geometry design and computer graphics.
• Traditional Boolean operation is mainly used in solid modeling to build a complex solid from primary solid e.g. cube, column, cone, sphere, etc.
• With the development of computer applications, there are many ways to represent digital models, such as parametric surface, meshes, point model, etc.
• Models become more and more complex, and features on models such as on statutary artworks are more detailed.
