GL2PS is a C library providing high quality vector output for any OpenGL
 application. The main difference between GL2PS and other similar libraries
 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...
 .
 GL2PS can currently create PostScript (PS), Encapsulated PostScript (EPS),
 Portable Document Format (PDF) and Scalable Vector Graphics (SVG) files,
 as well as LATEX files for the text fragments. GL2PS also provides limited,
 experimental support for Portable LaTeX Graphics (PGF). Adding new vector
 output formats should be relatively easy; you can also use the excellent
 pstoedit program to transform the PostScript files generated by GL2PS into
 many other vector formats such as xfig, cgm, wmf, etc.
