OpenCSG is a library that does image-based CSG rendering using OpenGL.
|
|
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. 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 result of such a CSG operation, 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.
|
|
|
|
Image-based CSG rendering (also z-buffer CSG rendering) is a term that
|
|
denotes algorithms for rendering 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.
