OpenCSG is a library that does image-based CSG rendering using OpenGL

CSG is short for Constructive Solid Geometry and denotes an approach to model complex 3D-shapes using simpler ones, i.e., two shapes can be combined by taking the union of them, by intersecting them, or by subtracting one shape of the other. The most basic shapes, which are not results of such CSG operations, are called primitives. Primitives must be solid, i.e., they must have a clearly defined interior and exterior. By construction, a CSG shape is also solid then.

To install OpenCSG, run the following command in macOS terminal (Applications->Utilities->Terminal)

sudo port install OpenCSG

To see what files were installed by OpenCSG, run:

port contents OpenCSG

To later upgrade OpenCSG, run:

sudo port selfupdate && sudo port upgrade OpenCSG
