3D graphic library for OS9000

I’m looking for a 3D graphic library for an application which runs on embedded system.
The operating system used for this application is OS9000. I’d like to ask whether there is an openGL libray (or other 3D graphic libraries) which can be used for my application. If not, is it possible to get source code of any openGL (or other) library and do portation for my application by myself? Thank you very much in advance!

You can take a look at mesa (http://www.mesa3d.org/) which is a open source implementations of OpenGL.

You may also check out tinygl (http://fabrice.bellard.free.fr/TinyGL/) which is targeted towards embedded systems.
