3DLDF is a package for 3D graphics with MetaPost output. It is written in C++ using CWEB and includes a User and Reference Manual in Texinfo format. 3DLDF currently doesn't include an input routine, so user code must be written in C++, compiled, and linked with the rest of the program. Please don't be put off by this! Updates and news will be made available at http://wwwuser.gwdg.de/~lfinsto1. This package was implemented by Laurence Finston.
