GL2PS: an OpenGL to PostScript printing library. GL2PS is a C library providing high quality vector output for any OpenGL application. The main difference between GL2PS and other similar libraries (see section 7) is the use of sorting algorithms capable of handling intersecting and stretched polygons, as well as non manifold objects. GL2PS provides advanced smooth shading and text rendering, culling of invisible primitives, mixed vector/bitmap output, and much more...
