Constructive solid geometry (CSG) is a technique used in solid modeling.
Constructive solid geometry allows a modeler to create complex surfaces or objects by using Boolean operators.
Typically, the used Boolean operations on sets are: union, intersection and difference.
The attached example shows the result of applying Boolean operations on spheres: union (green), intersection(red) and difference (yellow).
