Constructive solid geometry refers to the process of creating a three-dimensional object by combining or subtracting primitive shapes such as cubes, spheres, cylinders, and cones. Another synonym for constructive solid geometry is "Boolean modeling" which is based on the mathematical concepts of Boolean logic. Other similar terms include 3D modeling, Computer-Aided Design (CAD), and geometric modeling. Constructive solid geometry has applications in many fields, including engineering, architecture, and entertainment industry for creating realistic props, characters, and environments for movies, games, and simulations. It enables designers and engineers to visualize their ideas and designs before constructing them physically, thus saving time and resources.
