'''Crystal Space''' is a multi-platform 3D engine, and can be used as a framework to develop 3D applications (including games). It's written in object-oriented [C++], and currently runs on [Linux], [UNIX], [Mac OS X] and [Microsoft Windows]. It has [Swig] bindings set up for other scripting languages, which makes it a candidate for easy use from Tcl.
