Version 1.4.0-1 of
gl2ps (source only)
have been uploaded for cygwin.
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...
