Summary A library that does image-based ConstructiveSG rendering using OpenGL
Description OpenCSG is written in C++ and supports most modern graphics hardware. CSG is short for Constructive Solid Geometry and denotes an approach to model complex 3D-shapes using simpler ones. Image-based CSG rendering (also z-buffer CSG rendering) is a term for algorithms that render CSG shapes without an explicit calculation of the geometric boundary of a CSG shape. Such algorithms use frame-buffer settings of the graphics hardware, e.g., the depth and stencil buffer, to compose CSG shapes. OpenCSG implements a variety of those algorithms, namely the Goldfeather algorithm and the SCS algorithm, both of them in several variants.
