Sci3D is an interactive graphics program to display and manipulate 3-dimensional models. In spite of the Sci (for science) in the name, it can be used to display many types of objects. The Sci3D project contains several utilities that produce 3-dimensional objects from files of chemical information. such as molecular structure files. The graphics engine is Gramps, not to be confused with the genealogical programs gramps also here on sourceforge. Gramps was originally written in the early 1980's for use with the Evans and Sutherland Multi-Picture-System. It was written in Fortran and the current version retains much of that original code, but is updated to use OpenGL. It runs under linux, windows and osx. For linux and osx, it requires downloading some fortran libraries. This can be easy or not, depending on your linux distribution (I use Ubuntu or CentOS). It is so far rather difficult under osx. It works as is under windows with .dll files included in the distribtion.
