OpenCSG is a library that does image-based CSG rendering using
OpenGL. OpenCSG is written in C++ and supports most modern
graphics hardware using Microsoft Windows or the Linux operating
system. What is CSG, anyway? 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. SG is often used as fundamental modeling technique in CAD/CAM
applications. Here, image-based CSG rendering is the key to
interactively manipulate CSG shapes. Since OpenCSG renders even
complex CSG shapes fast, it can be advantageously used in such
applications. The OpenCSG library requires graphics hardware that
either supports frame buffer objects or PBuffers in OpenGL.
