This XObject lets MacroMind Director 3.0/3.1 access the SANE library functions such as sine, cosine, and so on. Normally Director does not include support of transcendental functions, and we originally thought that our project would need that capability, so I wrote this XObject. Later it turned out we didn't need access to those functions, so I pretty much forgot about the whole thing. I stumbled over this program again recently and thought that somebody out in net-land might have a use for it.
To simply use the XObject, you need only have Director 3.0 or 3.1. I recommend you copy the XObject into your Director document using ResEdit or a similar program. To edit/recompile this XObject you will need Think C 4.0 or higher (I think) and MacroMind's XObject Development kit.

If you find this of use, please drop me a note via email and let me know how they are working out for you! If there are any bugs I'd like to know about them too-- like I said, we're not using these in our project anymore so they haven't been rigorously tested.
