Sc21 is a MacOS X framework for integrating the Coin high-level 3D
framework into Cocoa applications. The combination of Coin and Sc21
(pronounced "Scandium", like the element) makes it possible to create
native, high-performance 3D graphics application on MacOS X based on the
industry standard Open Inventor API. Sc21 is written in Objective-C++
and comes as a Mac framework bundle. It also includes a custom Interface
Builder palette which lets developers drag and drop the most important
components into their project.
